#geowebchat transcript, 16 September 2014: Hand-drawn maps part 2


@mappingmashups Sep 15, 10:41am Tomorrow on #geowebchat is hand-drawn-maps part 2: show & tell & critique. Bring examples of hand-made cartography! Tue, Sep 16, 12pm PDT.

@mappingmashups Sep 16, 12:01pm Hey everybody, welcome to another #geowebchat! We are resuming last week’s discussion about hand-drawn maps: mappingmashups.net/2014/09/02/geo…

@mappingmashups Sep 16, 12:02pm Today’s #geowebchat will go into depth w/ a few examples of hand-drawn maps in the digital age. Let’s show-and-tell some of your favorites!

@mappingmashups Sep 16, 12:03pm As always w/ #geowebchat, make sure to include the hashtag in all your tweets. Tools like this help you follow along tweetchat.com/room/geowebchat

@mappingmashups Sep 16, 12:05pm Here’s a RT from last night via @mvexel for #geowebchat “@punkish: enough of this computer shit… old school punkish.org/Hand-Drawn-Maps

@mappingmashups Sep 16, 12:06pm Another for #geowebchat… does hand-drawn make more room for imagination? RT @re_sieber: Imaginary hand drawn maps pic.twitter.com/4BkFMo1lhZ

@erictheise Sep 16, 12:10pm hey all, i returned quite exhausted from @foss4g, but here are a few examples that popped to mind last time. #geowebchat

@mappingmashups Sep 16, 12:15pm …it’s either very quiet for today’s #geowebchat, or my internet connection is failing me (which might be the case today).

@re_sieber Sep 16, 12:16pm Unfortunately, I teach right in the middle of #geowebchat so I can’t easily contribute this Fall

@mappingmashups Sep 16, 12:17pm I’m very much enjoying the latest Pencil style by @aj_ashton in @Mapbox Studio: a.tiles.mapbox.com/v4/examples.a4… #geowebchat

@erictheise Sep 16, 12:17pm my examples are from fine arts; etchings by #EdRuscha of LA & SF street intersections crownpoint.com/artists/ruscha #geowebchat

@re_sieber Sep 16, 12:18pm Some resources “You are Here”, “Dictionary of Imaginary Places”, “Else/Where” #geowebchat (on break from class)

@mappingmashups Sep 16, 12:18pm RT @erictheise: in ’69 book club of calif published ‘designs on the land’ hand drawn maps from ranchers google.com/search?q=Desig… #geowebchat

@geodosu Sep 16, 12:18pm @mappingmashups @aj_ashton @Mapbox That is very nice #geowebchat

@erictheise Sep 16, 12:19pm some of his work with #mixografia, handmade paper/relief: mixographia.com/artist.php?bas… #geowebchat

@ebrelsford Sep 16, 12:21pm is today’s #geowebchat about anything particular within the umbrella of handdrawn maps?

@mappingmashups Sep 16, 12:21pm .@erictheise Those hand-drawn maps by ranchers are interesting in that the hand-drawnness helps communicate a connection w/ land #geowebchat

@SpatialProphet Sep 16, 12:21pm @mappingmashups #geowebchat I’ve a great “folk”map from Culebra PR.. in storage. Zzz #Dilapidated&DrunkRentalCarMerchantMakesForGoodMemories

@erictheise Sep 16, 12:23pm the color and line work in #EdRuscha LA/SF soft ground etchings pleases, size fits in hand, imagining impossible intersections. #geowebchat

@mappingmashups Sep 16, 12:23pm @ebrelsford Last time on #geowebchat we talked abt the role of hand-drawn maps in the digital age. Today we’re hoping to dive into examples

@mappingmashups Sep 16, 12:23pm .@ebrelsford …so, which of these maps resonates w/ us for deeper inspection? What can we learn from it vis-a-vis the digital? #geowebchat

@jonahadkins Sep 16, 12:24pm @mappingmashups At The #VirginiaGIS Conference, One Of My Fave Hand Drawn Web Maps Is …ssine-moi-une-ville.makina-corpus.net/#14/43.5934/1…. #geowebchat

@ebrelsford Sep 16, 12:24pm i always come back to the maps by the surveillance camera players eg notbored.org/LES-2011.jpg #geowebchat

@erictheise Sep 16, 12:25pm yes, @mappingmashups, maps appear naive, but show deep familiarity w/landmarks & features. think ranchers all lost land anyway. #geowebchat

@vtcraghead Sep 16, 12:25pm .@mappingmashups I’ll just point out that the CartoCSS “line-smooth” parameter is fake-hand-drawing-gold. farm8.staticflickr.com/7358/875612372… #geowebchat

@mappingmashups Sep 16, 12:25pm .@ebrelsford Great example. So what does a hand-made map of surveillance do different from this: appliedautonomy.com/isee.html ? #geowebchat

@jonahadkins Sep 16, 12:26pm @mappingmashups Also Tons Of Cool Ones At comiccartography.tumblr.com #geowebchat

@mappingmashups Sep 16, 12:27pm @erictheise Contrast w/ of the recurring themes in PPGIS: that professional-looking maps help disadvantaged groups get heard. #geowebchat

@ebrelsford Sep 16, 12:28pm @mappingmashups good point, I think the data is related, actually! or at least that the players collected data for iSee #geowebchat

@erictheise Sep 16, 12:28pm naive or pro, odds pretty stacked against ranchers in california land grabs, @mappingmashups #geowebchat

@erictheise Sep 16, 12:29pm some of the 92 maps that structure #PeterGreenaway’s #aWalkThroughH
google.com/search?q=peter… #geowebchat

@mappingmashups Sep 16, 12:29pm .@ebrelsford Interesting. But emphasizing the data is hand-collected reclaims a sense of humanity and individuality, perhaps. #geowebchat

@ebrelsford Sep 16, 12:30pm @mappingmashups here being hand-drawn exposes the methodology, too. “oh, i could have done that.” #geowebchat

@mappingmashups Sep 16, 12:30pm .@ebrelsford Even tho that particular map (notbored.org/LES-2011.jpg) probably was made after the fact, not during data collection #geowebchat

@mappingmashups Sep 16, 12:33pm @erictheise So do hand-made maps communicate narrative differently, Eric? (Not having seen A Walk Through H yet) #geowebchat

@mappingmashups Sep 16, 12:35pm .@erictheise I’m wondering if hand-made maps communicate the time it took to make the map, while digital maps seem instantaneous #geowebchat

@erictheise Sep 16, 12:35pm #PeterGreenaway modifies his maps as the film progresses. the subtitle of the film is ‘the reincarnation of an ornithologist’
#geowebchat

@spara Sep 16, 12:36pm Revealing my deepest nerd, I spent lot of time drawing D&D maps like this but with more detail upload.wikimedia.org/wikipedia/comm… #geowebchat

@erictheise Sep 16, 12:37pm when the deceased lingers, landmarks fade from map and endangers progression along underworld journey. #aWalkThroughH #geowebchat

@mappingmashups Sep 16, 12:37pm @spara But if you were growing up today, would you have made those maps digitally? In QGIS/TileMill/D3… or minecraft? ;) #geowebchat

@erictheise Sep 16, 12:38pm when he over-accelerates, he gets stuck in a territory with no exit yet available and has to cycle aimlessly. #aWalkThroughH #geowebchat

@spara Sep 16, 12:39pm @mappingmashups There are probably specific map generators for turn based games today. #geowebchat

@spara Sep 16, 12:42pm I used to Traveler and now there’s a map server for it travellermap.com/?x=6.295&y=-28… #geowebchat

@billdollins Sep 16, 12:43pm @spara Same here. Spent hours on them. #geowebchat

@mappingmashups Sep 16, 12:43pm So how about we take the last 15 minutes to look at the details of some of the artificial hand-drawn maps? #geowebchat

@mappingmashups Sep 16, 12:45pm I’m admiring the similarities and differences between …ssine-moi-une-ville.makina-corpus.net/#15/43.5901/1…. and a.tiles.mapbox.com/v4/examples.a4… #geowebchat

@spara Sep 16, 12:47pm Way back when, Mapblast would generate driveline/beeline maps that looked a lot like what a person would draw #geowebchat

@mappingmashups Sep 16, 12:48pm I love how the @makinacorpus map uses post-its for labels, for extra realism: …ssine-moi-une-ville.makina-corpus.net/#15/43.5962/1…. #geowebchat pic.twitter.com/pmOlKqzIJ8

@mappingmashups Sep 16, 12:51pm You can see @makinacorpus using smthg like line-smooth as @vtcraghead mentioned …ssine-moi-une-ville.makina-corpus.net/#19/43.59922/1… #geowebchat pic.twitter.com/6eURNxCsIr

@spara Sep 16, 12:51pm An example strip maps buildinghistory.org/images/Ogilby1… AAA used to generate them when you asked for one. #geowebchat

@vtcraghead Sep 16, 12:54pm .@mappingmashups @makinacorpus HOT LEGEND. Off-topic, but that’s a great example of a novel implementation in an interactive. #geowebchat

@spara Sep 16, 12:58pm I’ve always liked the AAA Triptiks google.com/search?q=aaa+s… #geowebchat

@mappingmashups Sep 16, 12:59pm Well, we are reaching the end of another #geowebchat. Thanks for all the links, everybody! Transcript here soon: mappingmashups.net/geowebchat

@mappingmashups Sep 16, 1:00pm Next #geowebchat is in 3 weeks, on Oct 7. The topic will be “Cartography and Time”, since that’s the theme of #NACIS which starts that week.

@mappingmashups Sep 16, 1:23pm RT @punkish: re Hand Drawn Maps (punkish.org/Hand-Drawn-Maps), search sucks but the battery life is infinite #geowebchat

#geowebchat transcript, 2 September 2014: Hand-drawn maps


@danielledai Sep 02, 9:33am Hand-drawn maps #geowebchat w/@mappingmashups today, 12 PST. github.com/ddai/hand-draw… yay! #maps #cartography #drawing

@mappingmashups Sep 02, 11:17am Starting at noon today PDT: #geowebchat about hand-drawn #cartography in the digital age, with @danielledai! Join us in just a few minutes!

@mappingmashups Sep 02, 12:01pm Welcome everyone to today’s #geowebchat about hand-drawn cartography. Thanks @danielledai for helping lead the discussion today!

@mappingmashups Sep 02, 12:02pm Today’s #geowebchat is a spin-off from a recent @MaptimeSF meetup we had about hand-drawn maps. Did anyone joining us today also go to that?

@danielledai Sep 02, 12:03pm Thanks @mappingmashups! We hosted a @MaptimeSF on hand-drawn maps recently, resources/inspiration here: github.com/ddai/hand-draw… #geowebchat

@mappingmashups Sep 02, 12:04pm As with any #geowebchat, make sure you include the hashtag in all your tweets so everyone can follow along.

@danielledai Sep 02, 12:06pm Question raised: what is the role of hand-drawn maps in the digital age? #geowebchat

@mappingmashups Sep 02, 12:06pm So, who attending our #geowebchat today has made any hand-drawn maps lately? For fun or for work (or anything else)?

@mappingmashups Sep 02, 12:09pm .@danielledai Do we think there’s been a resurgence in interest in hand-drawn maps because digital maps are so ubiquitous? #geowebchat

@erictheise Sep 02, 12:10pm i used to always start my class at @SFCB by having people draw a map of how they got there that day, then to share w/neighbor. #geowebchat

@erictheise Sep 02, 12:11pm by doing that, people became aware of inherent choices in mapmaking, what to exclude, scale, labeling, success in communication #geowebchat

@bdon Sep 02, 12:12pm @danielledai @mappingmashups #geowebchat see LineDrive by @magrawala ; hand-drawn generalizations for wayfinding graphics.stanford.edu/papers/routema…

@jonahadkins Sep 02, 12:12pm @mappingmashups Hand drawn exercise to help kids understand “layers”, without ever saying “layers” #geowebchat pic.twitter.com/8HTIchHfbf

@mappingmashups Sep 02, 12:12pm .@erictheise That’s also an exercise in mental mapping. Is there an inherent overlap between mental maps and hand-drawn maps? #geowebchat

@danielledai Sep 02, 12:14pm .@bdon @mappingmashups @magrawala Neat! This reminds me of @conveyal’s transitive.js work for line maps conveyal.com/blog/2014/04/2… #geowebchat

@MapHugger Sep 02, 12:14pm .@mappingmashups @danielledai Yes, exactly! To note: 1/3rd of maps in the upcoming @NACIS_Atlas include hand-drawn elements #geowebchat

@danielledai Sep 02, 12:16pm @MapHugger Neat! Do you have examples online of these maps @NACIS_Atlas? @mappingmashups #geowebchat

@mappingmashups Sep 02, 12:18pm .@jonahadkins your example (& @erictheise’s) suggests that hand-making maps is a way to teach concretely about how maps are made #geowebchat

@mappingmashups Sep 02, 12:19pm .@jonahadkins @erictheise …so, construction of maps as a parallel to deconstructing maps. #geowebchat

@MapHugger Sep 02, 12:19pm .@mappingmashups @erictheise Mental maps feel better hand-drawn vs digital. Makes the subjective nature of the map obvious #geowebchat

@danielledai Sep 02, 12:20pm .@mappingmashups @erictheise Mental maps as a first version of hand-drawn maps? Check this out: nytimes.com/2012/02/05/opi… #geowebchat

@mappingmashups Sep 02, 12:20pm .@MapHugger @erictheise But it makes me wonder, is it just that digital maps are (still) so bad at rendering the subjective? #geowebchat

@MapHugger Sep 02, 12:21pm @danielledai We haven’t revealed the full lineup, but there’s a peek at the table of contents here: atlasofdesign.org/purchase/ #geowebchat

@golandmark Sep 02, 12:21pm Hand-drawn maps when giving directions is much easier than explaining it only using words and road names #geowebchat

@MapHugger Sep 02, 12:23pm .@mappingmashups @erictheise Digital can render subjectivity. But the soft/minimalist look most digital maps have don’t cut it #geowebchat

@erictheise Sep 02, 12:24pm digital maps can certainly render some subjectivities, but i think it’s expressiveness, & speed at expressiveness, they lack. #geowebchat

@mappingmashups Sep 02, 12:26pm @MapHugger @erictheise That brings up another thing I’d like to talk about: digital maps that try to mirror hand-drawn styles #geowebchat

@geothinkca Sep 02, 12:26pm .@MapHugger @mappingmashups @erictheise Digital maps require some expertise/training/tools -inherently biasing the sample #geowebchat

@danielledai Sep 02, 12:27pm @mappingmashups @MapHugger @erictheise Yes. @stamen’s watercolor tiles & @Mapbox’s pencil tiles are quite delightful #geowebchat

@vtcraghead Sep 02, 12:30pm @mappingmashups Because the only thing cooling than hand-drawing a map is pretending you did. flickr.com/photos/vtcragh… #geowebchat

@MapHugger Sep 02, 12:30pm @mappingmashups I like ‘em. The digital-but-looks-traditional trend is also big in illustration and graphic design too. #geowebchat

@mappingmashups Sep 02, 12:30pm .@danielledai Yeah, and I’m also thinking of projectlinework.org, or @mapmeld’s recent Vincent van Gogh style map #geowebchat

@danielledai Sep 02, 12:30pm Do digital maps with this styling replace hand-drawn maps? Are hand-drawn maps viewed more as art? #geowebchat @mappingmashups @erictheise

@mappingmashups Sep 02, 12:32pm .@danielledai And why do we all love these digitally-generated “hand-drawn” maps? Are they ever better than the real thing? #geowebchat

@vtcraghead Sep 02, 12:33pm .@danielledai Lending credence to the idea of it as art, I always have trouble using stamen-watercolor with data. #geowebchat

@erictheise Sep 02, 12:33pm i think hand drawn maps are considered art or fetish items, @danielledai. technically, woodcut, engraved, litho, all not unique. #geowebchat

@mappingmashups Sep 02, 12:34pm Here’s @mapmeld’s van Gogh map: mapmeld.github.io/van-gogh-map/#… made with @Mapbox GL #geowebchat

@erictheise Sep 02, 12:34pm in that way, digital is very much a logical next step in mass production, @danielledai, after classic printing techniques. #geowebchat

@mappingmashups Sep 02, 12:35pm .@vtcraghead @danielledai Interestingly, lots of other people don’t have problems using Watercolor with data. It’s surprising! #geowebchat

@erictheise Sep 02, 12:36pm and though we admire 19th cent engraved coast & geodetic maps and earlier woodcuts, @danielledai, they were about distribution. #geowebchat

@vtcraghead Sep 02, 12:36pm @mappingmashups @danielledai I’d love to see examples of it meshing. The effort hurdle is in matching the level of stylization. #geowebchat

@mappingmashups Sep 02, 12:36pm @vtcraghead @danielledai Although @Elijah_Meeks claims that Watercolor gives his map data viz “humanities street cred” :) #geowebchat

@MapHugger Sep 02, 12:37pm @mappingmashups @danielledai They’re often easier to make/publish than an actual hand-drawn map, if nothing else. #geowebchat

@danielledai Sep 02, 12:38pm @mappingmashups @mapmeld @Mapbox Wow, neat! How about pointalism following Seurat… or ABSTRACT? I wonder how that’d look. #geowebchat

@mappingmashups Sep 02, 12:38pm @erictheise @danielledai Well, I suppose that physical maps (whether hand-drawn or mass-produced) are all becoming fetish items #geowebchat

@mappingmashups Sep 02, 12:39pm RT @mapmeld: @danielledai also check out an older experiment in this handdrawn map mimic space crayonmap.herokuapp.com #geowebchat

@danielledai Sep 02, 12:40pm @erictheise we’re having that discussion @sfmta_muni – making print maps v better digital ones for production/consumption #geowebchat

@danielledai Sep 02, 12:42pm Another pt: hand-drawn maps are considered art, but not everybody considers themselves an artist @mappingmashups @erictheise #geowebchat

@vtcraghead Sep 02, 12:42pm .@mappingmashups #geowebchat Even w/ compositing there’s so much eye-catch & contrast in the watercolor: pic.twitter.com/8ZUygCEl2t

@danielledai Sep 02, 12:44pm @mappingmashups @erictheise I encouraged tracing @MaptimeSF. Stylized hand-drawn digital maps, tracing, helps overcome barrier? #geowebchat

@danielledai Sep 02, 12:46pm Slight #geowebchat tangent: This @xkcdComic on map projections is awesome: xkcd.com/977/

@erictheise Sep 02, 12:47pm barrier of not self-identifying as artist @danielledai? seems most handmade maps, if not Art, serve particular, practical ends. #geowebchat

@danielledai Sep 02, 12:48pm MT @golandmark I enjoyed hand-drawn tourist maps while I traveled behance.net/gallery/139000… #geowebchat

@mappingmashups Sep 02, 12:49pm @danielledai @xkcdComic Yeah, arguably @xkcd is the world’s most famous hand-drawn cartographer #geowebchat

@mappingmashups Sep 02, 12:51pm RT @colemanm: @jonahadkins @mappingmashups That’s fantastic – love the interstate highway shields! #geowebchat

@mappingmashups Sep 02, 12:54pm @danielledai @erictheise @MaptimeSF …and I suppose @xkcd is also the most famous hand-drawn map tracer, too. #geowebchat

@erictheise Sep 02, 12:55pm i wonder how different it is, the “but i can’t draw!” reaction to a) draw my portrait & b) draw me a map of how to get to store. #geowebchat

@danielledai Sep 02, 12:56pm @erictheise Yes, fair. I’ve also been thinking about this creative confidence business in making maps creativeconfidence.com #geowebchat

@MapHugger Sep 02, 12:56pm @mappingmashups @danielledai Randall manages to make maps loose/sketchy but also data-driven/trustworthy what-if.xkcd.com/53/ #geowebchat

@jonahadkins Sep 02, 12:57pm .@mappingmashups My fave hand drawn map – @cassieramone “Mew Mexico” flickr.com/photos/cassier… – I also have the shirt :) #geowebchat

@erictheise Sep 02, 12:59pm it might be nice to do a part 2, where people show/critique examples of hand drawn maps important to them, @jonahadkins. #geowebchat

@mappingmashups Sep 02, 12:59pm @erictheise The practical ends are the diff in your “but I can’t draw” tweet, Eric. Giving directions vs general purpose map. #geowebchat

@erictheise Sep 02, 1:00pm aboriginal dreamtime maps are hard to get my western head around, & i also like shaker maps, as examples. #geowebchat

@jonahadkins Sep 02, 1:01pm @erictheise In! #geowebchat cc @mappingmashups

@erictheise Sep 02, 1:01pm exactly, @mappingmashups, that’s why i question whether there’s as much of a barrier. #geowebchat

@mappingmashups Sep 02, 1:01pm Thanks @danielledai and everyone else who joined today’s #geowebchat! We’ve reached the end of our hour. Next chat is same time, Sep 16.

@mappingmashups Sep 02, 1:03pm .@jonahadkins @erictheise I like that idea, too. What about September 16 as hand-drawn-maps part 2: show & tell & critique? #geowebchat

@erictheise Sep 02, 1:05pm sounds good to me, i’ll drag out my old @SFCB notes, @mappingmashups @jonahadkins #geowebchat

@danielledai Sep 02, 1:07pm Thanks @mappingmashups for my 1st #geowebchat. Excited to look in depth at today’s links. Def in for part 2 @erictheise @jonahadkins

@mappingmashups Sep 02, 2:19pm RT @magrawala: Looks cool! transitive.js conveyal.com/blog/2014/04/2… More hand-drawn maps vis.berkeley.edu/papers/dmaps/ #geowebchat

@mappingmashups Sep 02, 2:20pm RT @jonahadkins: Bookmarking: comiccartography.tumblr.com , flickr.com/photos/cassier… , & Scans From :’The Map As Art’ #geowebchat

@mappingmashups Sep 02, 2:20pm RT @Elijah_Meeks: The visual aesthetic of trad. base maps can be an implicit claim to precision of overlaid data. #geowebchat

@mappingmashups Sep 02, 2:20pm RT @mxfh: @visionscarto says in certain cases the fuzziness of the data favors a hand drawn style mapdesign.icaci.org/2014/08/mapcar… #geowebchat

@mappingmashups Sep 02, 3:10pm RT @visionscarto: Actually my maps are not digitally-generated but really hand drawn Only text and background digitaly-assembled #geowebchat

@visionscarto Sep 02, 3:13pm @mappingmashups #geowebchat There is more of these on visionscarto.net freely accessible in HD so that you can have a close look

#geowebchat transcript, 19 August 2014: Maps and abstraction


@mappingmashups Aug 19, 9:42am Today on #geowebchat: Maps and abstraction. When is a map no longer a map? Join the chat at 12pm PDT 3pm EDT 8pm BST. Please RT!

@erictheise Aug 19, 11:58am rippin’ circular breathing sax piece on @revsnakeens’ #NewEdge on @wmbr, #geowebchat at noon re: maps & abstraction

@mappingmashups Aug 19, 11:59am Starting in a few moments: #geowebchat about maps & abstraction. Does a “map” have to be geographic? When is realism a disadvantage w/ maps?

@mappingmashups Aug 19, 12:00pm As always with #geowebchat, make sure you include the hashtag in all your tweets. Follow along with us here: tweetchat.com/room/geowebchat

@mappingmashups Aug 19, 12:00pm If you want to ignore #geowebchat, see if your twitter client can mute the hashtag. We’ll be chatting for the next hour.

@mappingmashups Aug 19, 12:04pm For today’s #geowebchat, let’s begin by sharing your favorite map-that’s-not-a-map. What are the boundaries of “mapping” to you?

@erictheise Aug 19, 12:04pm are we starting with 4′ 33″ today? #geowebchat

@tinyswirl Aug 19, 12:05pm @mappingmashups maps don’t have to be geographic but a “true” map has a spatial element eg: a map of the human body #geowebchat

@mappingmashups Aug 19, 12:05pm @erictheise Hah! Well, let’s take that literally: could we think of absence or whitespace on maps as a form of abstraction? #geowebchat

@erictheise Aug 19, 12:06pm i consider graphic music scores as mappings, some geo, most not. blog.wfmu.org/freeform/2007/… #geowebchat

@mappingmashups Aug 19, 12:07pm In fact, at @stamen yesterday we met with @erinreiss who made this map using whitespace and abstraction: seethroughmaps.wordpress.com/2013/10/27/rei… #geowebchat

@mappingmashups Aug 19, 12:08pm @tinyswirl So a “true” map is somehow constrained by real-world spatial orientation of objects? #geowebchat

@mapperz Aug 19, 12:09pm #geowebchat Open Fiction Map opengeofiction.net/#map=6/59.210/… non-real geographic

@RobKitchin Aug 19, 12:09pm need to make distinction btwn spatialisation and maps. One adds spatial refs to non-spatial data & vizs, other vizs spatial data #geowebchat

@mappingmashups Aug 19, 12:09pm @tinyswirl Reminds me of the distinction between #dataviz (spatial orientation undefined) and #sciviz (layout defined) #geowebchat

@mappingmashups Aug 19, 12:10pm @tinyswirl …this leaving #geoviz in between, where two or three dimensions are fixed, but data overlays need not be. #geowebchat

@erictheise Aug 19, 12:10pm seems that there’s a certain tipping point where absence becomes abstraction, @mappingmashups, but absence can also focus. #geowebchat

@tinyswirl Aug 19, 12:11pm @mappingmashups IMO, yes. Whether it’s sketched on the back of an envelope or a cartographic masterpiece. Or memorised! #geowebchat

@erictheise Aug 19, 12:11pm “vignetting” is a type of absence, @mappingmashups, but the intent is to make you focus on cartographer’s agenda. #geowebchat

@map_ebooks Aug 19, 12:11pm Our notion of abstraction is based on predicate mapping which maps predicate symbols into abstract predicate symbols. #geowebchat

@mapperz Aug 19, 12:12pm cartogram scapetoad.choros.ch software #geowebchat #nongeo

@WxDan Aug 19, 12:12pm One of my favorites is an old XKCD “map” of IP address allocations. Is this really a map or just dataviz? xkcd.com/195/ #geowebchat

@mappingmashups Aug 19, 12:12pm Ooh, welcome to #geowebchat and to twitter, @map_ebooks!

@tinyswirl Aug 19, 12:13pm @mappingmashups I think I follow! lol new to #geowebchat

@rmcooper4 Aug 19, 12:13pm @map_ebooks “predicate mapping”? Where/Who does that idea come from? #intrigued #geowebchat

@erictheise Aug 19, 12:13pm as labels drop off of maps & geometry comes to the fore, that’s when abstract/concrete oscillates, @mappingmashups #geowebchat

@mappingmashups Aug 19, 12:14pm @mapperz Cartograms are a good example of abstraction and geo/nongeo. Raises question of what geographic position is needed for. #geowebchat

@mappingmashups Aug 19, 12:15pm @mapperz the spatial orientation on most cartograms mainly to help reader find data points (based on familiarity w/ other maps) #geowebchat

@mapperz Aug 19, 12:16pm @mappingmashups Voronoi treemap #maps via @kennethfield cartonerd.blogspot.co.uk/2014/08/vorono… #nongeo #geowebchat pic.twitter.com/WPbes9Qa8I

@tinyswirl Aug 19, 12:18pm @WxDan The equivalent of a “Mind Map” for the ‘net. Two things with a *perceived* spatial element (eg: a “train of thought”). #geowebchat

@mappingmashups Aug 19, 12:18pm @rmcooper4 @map_ebooks “predicate mapping” comes from a markov chain, no? So meta. #geowebchat

@tinyswirl Aug 19, 12:19pm @RobKitchin @WxDan Ah, that makes the term clearer for me now. Thank you #geowebchat

@mappingmashups Aug 19, 12:19pm RT @RobKitchin: @WxDan It’s a spatialisation. We put 100s in the Atlas of Cyberspace. Free PDF download: kitchin.org/atlas/contents… #geowebchat

@mappingmashups Aug 19, 12:21pm @tinyswirl @WxDan Mind Maps and Mental Maps seem to mean different things to non-geographers and geographers #geowebchat

@mappingmashups Aug 19, 12:22pm @tinyswirl @RobKitchin @WxDan & the spatialization isn’t always simply perceived or subjective. Self-organizing maps for ex #geowebchat

@map_ebooks Aug 19, 12:23pm (But by spatialisation I do not mean merely visualisation: a person who can only visualise can only take a limited view #geowebchat

@mappingmashups Aug 19, 12:25pm @map_ebooks Are you talking about 3+ dimensions? Or are you referring to non-visual (ie tactile) ways of knowing space? #geowebchat

@tinyswirl Aug 19, 12:26pm @mappingmashups @RobKitchin @WxDan Disagree. Self-organizing maps definitely have perceived spatial element. #geowebchat

@mappingmashups Aug 19, 12:27pm RT @RobKitchin: @tinyswirl @WxDan usually uses a measure such as semantic proximity that can be used to create spatial referents #geowebchat

@RobKitchin Aug 19, 12:28pm @tinyswirl @mappingmashups @WxDan after constructed but not necessarily beforehand. That’s what spatialisation creates #geowebchat

@mappingmashups Aug 19, 12:28pm @tinyswirl @RobKitchin @WxDan I mean the spatiality is not determined by the map-maker’s subjective perception. #geowebchat

@mappingmashups Aug 19, 12:32pm @RobKitchin Is each spatialization a one-off only valid for that visualization? Is “real” geog the only shared spatialization? #geowebchat

@mappingmashups Aug 19, 12:33pm What distortions of spatial locations or artificial spatializations persist and take on lives of their own? Subway maps? #geowebchat

@map_ebooks Aug 19, 12:33pm multidimensional visualizations are not well-suited for this problem bc of the volume of information and its unstructured nature #geowebchat

@tinyswirl Aug 19, 12:34pm @RobKitchin @WxDan Ah, yes I think I misunderstood what @mappingmashups was getting at. Actual spatial=map (vs created spatial)? #geowebchat

@mappingmashups Aug 19, 12:36pm RT @RobKitchin: @mappingmashups to a certain degree, but the same rule set and data should produce same/similar spatialisations #geowebchat

@mappingmashups Aug 19, 12:38pm @tinyswirl Yeah, it’s the challenge of communicating w/ the constraints of twitter. I think I wasn’t explaining well. #geowebchat

@mappingmashups Aug 19, 12:39pm MT @RobKitchin: subway maps are topological maps not spatialisations. Don’t add spatial to non-spatial data but rearrange layout #geowebchat

@tinyswirl Aug 19, 12:42pm @mappingmashups This is my first #geowebchat so I’m just being a bit slow.

@mappingmashups Aug 19, 12:42pm So when can/should spatializations (aka data visualizations) borrow from the language of cartography? When shouldn’t they? #geowebchat

@mappingmashups Aug 19, 12:44pm Usually I see data viz adopt cartographic styles for purely aesthetic reasons, like infographics using the tropes of subway maps #geowebchat

@mappingmashups Aug 19, 12:46pm @EcoAndrewTRC Good point. In the sense that all projections (& all maps) are abstractions, Mercator is like a shared mental map #geowebchat

@RobKitchin Aug 19, 12:46pm @mappingmashups when they are used as a map; Difference spatialisation & data viz per se is map-like qualities of former #geowebchat

@TheMapSmith Aug 19, 12:46pm @mappingmashups There is probably an academic distinction between carto and non-carto, but aren’t they both “design”? #geowebchat

@RobKitchin Aug 19, 12:47pm @mappingmashups we have an extensive discussion of maps vs spatialisations and cartographic theory in Mapping Cyberspace book #geowebchat

@mappingmashups Aug 19, 12:49pm @TheMapSmith Yes, design should be a part of both, & many of the same design guidelines apply to carto & non-carto. But not all? #geowebchat

@TheMapSmith Aug 19, 12:50pm Sometimes I put north arrows on infographics just for fun, does that count? #geowebchat

@tinyswirl Aug 19, 12:50pm Graphic with baby – spatialization or map? MT”@Visually: ow.ly/Av44c by @LandonDonovan81 pic.twitter.com/qfvQQQm9rs” #geowebchat

@mappingmashups Aug 19, 12:52pm @TheMapSmith Since nobody puts them on maps anymore, why not? #geowebchat

@tinyswirl Aug 19, 12:53pm @mappingmashups @TheMapSmith which ones aren’t? #geowebchat

@RobKitchin Aug 19, 12:54pm @tinyswirl @Visually @LandonDonovan81 Neither. The graphic conveys no meaningful information through its spatial arrangement #geowebchat

@mappingmashups Aug 19, 12:56pm @tinyswirl @TheMapSmith That might be a topic for another #geowebchat. :) Similar to prev chats about whether cartographers are obsolete…

@mappingmashups Aug 19, 12:57pm Well, we are nearing the end of our #geowebchat about maps and abstraction. What did we miss? Any aspects we should revisit another time?

@TheMapSmith Aug 19, 12:57pm Another major non-spatial/spatial visualization is the straight line diagram. Very important in some industries #geowebchat

@mappingmashups Aug 19, 12:57pm Whether (and how) cartographic design rules differ from non-cartographic design rules would definitely be a good future #geowebchat topic.

@mappingmashups Aug 19, 12:59pm @TheMapSmith Right. Flattening 2 or 3 dimensions into a 1 dimensional “map”. Interesting. #geowebchat.

@tinyswirl Aug 19, 12:59pm @mappingmashups sounds like a #geowebchat I can learn a lot from :)

@mappingmashups Aug 19, 1:00pm Our next #geowebchat will be tangentially related: we’ll be discussing the role of hand-drawn maps in the geoweb era. Tue Sep 2, same time.

@mappingmashups Aug 19, 1:01pm Thanks everyone for joining today’s #geowebchat. Look forward to chatting with you next time!

@tinyswirl Aug 19, 1:02pm @mappingmashups @TheMapSmith like a proximity analysis – eg: concentration of contaminants according to distance from source? #geowebchat

@MapHugger Aug 19, 1:30pm @mappingmashups Late to #geowebchat, but my two favorite unmaps: l-degrees.com thebolditalic.com/articles/3202-…

@jasondowns Aug 19, 4:13pm @mappingmashups I always miss #geowebchat because of time differences. Today’s looked awesome. I love this particular topic. Thanks.

@mappingmashups Aug 19, 5:12pm Definitely relevant to today’s #geowebchat: “Experiments in Literary Cartography” visualandcriticalstudies.com/2014/08/11/ber…

#geowebchat transcript, 15 July 2014: Mapping the geographies of sport


@mappingmashups Jul 15, 10:12am Today on #geowebchat: mapping the geographies of sport. Join us for 1 hour starting at 12pm PDT, 3pm EDT, 8pm BST.

@mappingmashups Jul 15, 10:32am What’s @nytgraphics’s most famous map? The one about baseball fans, apparently. nytimes.com/interactive/20… #geowebchat pic.twitter.com/YHvxlHh844

@erictheise Jul 15, 11:01am keeping an eye on two back-to-back webchats today: #RoadtoCicerone 11-12 PDT; #geowebchat 12-1 PDT on geography of sport.

@mappingmashups Jul 15, 12:00pm Welcome to today’s #geowebchat! We’re talking about mapping the geographies of sport. Interpret that as broadly as you like!

@mappingmashups Jul 15, 12:01pm If you want to join in with #geowebchat, just make sure to include the hashtag in all your tweets. Follow along here: tweetchat.com/room/geowebchat

@mappingmashups Jul 15, 12:01pm (And if you want to ignore #geowebchat, see if your twitter client can mute the hashtag. We’ll be at it for about one hour)

@mappingmashups Jul 15, 12:03pm For “mapping sport” that could include mapping the action in the game, the venues, the players, or broader social impacts… #geowebchat

@mappingmashups Jul 15, 12:05pm For example, here was an interesting “map” of the range of various #worldcup goalkeepers from @nytimes: nytimes.com/interactive/20… #geowebchat

@bdon Jul 15, 12:05pm #geowebchat a look at what NBA teams would look like if every player “went home” like LeBron to NE Ohio: imgur.com/a/79WvK

@mappingmashups Jul 15, 12:05pm …which reminds me of some heat maps (using hexbins!) of NBA shots: infosthetics.com/archives/2012/… #geowebchat

@bdon Jul 15, 12:05pm #geowebchat poses interesting spatial questions e.g. where to draw the line between Knicks/Nets or Lakers/Clips

@skorasaurus Jul 15, 12:05pm @kirkgoldsberry designer of some great basketball visualizations (maps?) deserves a mention. ex: grantland.com/the-triangle/t… #geowebchat

@skorasaurus Jul 15, 12:08pm much more attention to analytics in #nba in past 3yrs, & spatial is a big component of it. (shot charts, player mvment) #geowebchat

@mappingmashups Jul 15, 12:09pm .@bdon Right, and something like the #worldcup makes us think about what “home” and nationality mean: visualizing.org/visualizations… #geowebchat

@bdon Jul 15, 12:09pm Awkward geographical constructions perpetuated through sport: New England, Golden State, Anaheim, Northeast Ohio #geowebchat

@mappingmashups Jul 15, 12:10pm Yes @skorasaurus, let’s definitely use a big definition of “map” today to include dataviz like @kirkgoldsberry’s. #geowebchat

@geodosu Jul 15, 12:11pm @mappingmashups @skorasaurus @kirkgoldsberry Here’s one of player links at world cup, via clubs: is.gd/4vaa0S #geowebchat

@jqtrde Jul 15, 12:12pm A map of English Premier League stadiums that I made: a.tiles.mapbox.com/v3/jacques.h68… #geowebchat

@mapperz Jul 15, 12:12pm #geowebchat worldcup final twitter #map huffingtonpost.co.uk/2014/07/14/wor…

@bdon Jul 15, 12:12pm #geowebchat major barrier to commoditized spatial analytics in sports is proprietary data collection: news agencies, teams willing to pay $$

@mappingmashups Jul 15, 12:13pm .@bdon Some might call them awkward, but to others they are more “common sense” like this: commoncensus.org/maps.php #geowebchat

@jqtrde Jul 15, 12:13pm And another of the Bundesliga a.tiles.mapbox.com/v3/jacques.h6b… #geowebchat

@mappingmashups Jul 15, 12:14pm .@jqtrde Right, and mapping stadiums is also something that can emphasize differences in data quality: wired.com/2014/06/google… #geowebchat

@mappingmashups Jul 15, 12:15pm After #OpenStreetMap got to brag about its better Sochi maps (wired.com/2014/02/sochi-…), Google got the upper hand this time… #geowebchat

@skorasaurus Jul 15, 12:16pm #geowebchat, sport fields are relatively easy to identify in sat. imagery; & map for #osm, etc #geowebchat

@rmcooper4 Jul 15, 12:18pm On politics of stadiums: Atl Braves used maps to justify move from downtown to Cobb Co. #geowebchat goo.gl/Z9nZOL

@skorasaurus Jul 15, 12:21pm wired article reminds me that maps of stadium amenities (concession stands, etc.,) are underutilized.. #geowebchat

@mappingmashups Jul 15, 12:23pm @rmcooper4 Very interesting! A reversal to admit that the fans are in the suburbs, rather than stadium-as-redevelopment-tool #geowebchat

@skorasaurus Jul 15, 12:25pm @rmcooper4 nice find homeofthebraves.com/wp-content/upl… (locations of tix sold for braves games). Great idea/premise of map; poor execution #geowebchat

@mappingmashups Jul 15, 12:28pm Revisiting @bdon’s comment about what-if NBA players went “home” here are some maps of players by state deadspin.com/infographics-w… #geowebchat

@mappingmashups Jul 15, 12:31pm This @FiveThirtyEight piece gets into the intersection of int’l economics, & the geodemographics of fans: fivethirtyeight.com/features/why-c… #geowebchat

@rmcooper4 Jul 15, 12:38pm @mappingmashups @bdon Flip-side: what teams are “closest” to being full of native (sorry to use that term) players. #geowebchat

@mappingmashups Jul 15, 12:40pm @skorasaurus @rmcooper4 Comparing ATL map w/ NYT: a ring of fewer fans in burbs nytimes.com/interactive/20… #geowebchat pic.twitter.com/QMnJAP5QCV

@mappingmashups Jul 15, 12:45pm Also, for #geowebchat let’s not forget self-quantification that also counts as cartographies of sport: strava.com/saturday-heatm… #geowebchat

@erictheise Jul 15, 12:50pm @mappingmashups, on the #quantifiedSelf front, i was happy that gps tracking was added in latest release of @fitbit’s iphone app #geowebchat

@geodosu Jul 15, 12:52pm @mappingmashups I’m intrigued as to technologies used to track players in pro sports not GPS, I guess #geowebchat

@mappingmashups Jul 15, 12:53pm At @stamen we’re having quite a conversation about sports teams from places like Anaheim, Golden State, New England… #geowebchat

@erictheise Jul 15, 12:53pm related to #quantifiedSelf if not narrower sport topic, interesting cfp: computer.org/portal/web/com… #geowebchat

@mappingmashups Jul 15, 12:54pm For Golden State, NE, & things like the Arizona pro teams, it’s about appealing to a larger fanbase from nearby cities, no? #geowebchat

@mappingmashups Jul 15, 12:58pm We’re about to wrap up this #geowebchat about sport, but I can’t resist dropping one last #critgeog link ibtimes.com/why-rios-favel… #geowebchat

@rmcooper4 Jul 15, 12:58pm @mappingmashups Maybe sport culture in the reg too. Indy has Indiana Pacers(nba) and Indy Colts(nfl). State culture is bball #geowebchat

@mappingmashups Jul 15, 1:01pm Thanks everybody for joining today’s #geowebchat, but our time is up. Next chat is in 3 weeks on August 5. I need a guest host, any takers?

@mappingmashups Jul 15, 1:06pm RT @mpmckenna8: @mappingmashups how about ‘dem Santa Clara 49ers. Also New York Giants and Jets in NJ. #geowebchat

#geowebchat transcript, 1 July 2014: Vector cartography part 2


@mappingmashups Jul 01, 8:35am Today on #geowebchat: part 2 of our chat about vector-based web cartography mappingmashups.net/2014/06/17/geo… Join us at 12pm PDT, Tues July 1!

@mappingmashups Jul 01, 12:00pm Welcome to our #geowebchat about vector mapping! We’re continuing the chat from last time: mappingmashups.net/2014/06/17/geo… All are welcome to join.

@mappingmashups Jul 01, 12:01pm If you want to join #geowebchat, just include the hashtag in all your tweets. tweetchat.com/room/geowebchat is a handy tool, too.

@mappingmashups Jul 01, 12:01pm And if you want to ignore these #geowebchat tweets, see if your twitter client has the ability to mute hashtags.

@mappingmashups Jul 01, 12:03pm I’ve been browsing WebGL map implementations for #geowebchat: There’s the new @Mapbox GL, cool stuff from @mapzen, also @GLMapFramework

@mappingmashups Jul 01, 12:05pm At the end of the last #geowebchat, @professorlemeza post this great @mapzen demo: vector-map.mapzen.com/#mapzen,40.757… Has anyone played with it yet?

@bohuang3d Jul 01, 12:09pm @mappingmashups @professorlemeza @mapzen #geowebchat love it. What’s the vector format like

@erictheise Jul 01, 12:10pm @mappingmashups, been watching progress of @professorlemeza & @meetar’s demos, looking at learningwebgl.com when i can. #geowebchat

@mappingmashups Jul 01, 12:12pm @bohuang3d Here is the repository for the @mapzen demo @professorlemeza posted: github.com/meetar/tangram… cc @meetar #geowebchat

@mappingmashups Jul 01, 12:13pm @bohuang3d Does your SenseEarth.com site use WebGL? #geowebchat

@mappingmashups Jul 01, 12:16pm Also, in last #geowebchat we talked mainly about vector data tiles and WebGL, but arguably #d3js is another vector revolution in web maps…

@mappingmashups Jul 01, 12:16pm RT @woolie: @bohuang3d @mapzen @professorlemeza @meetar Awesome elevator animation, reminds me of :) pic.twitter.com/Pz1XrMWDTw #geowebchat

@apollolm Jul 01, 12:17pm #geowebchat Been experimenting with consuming Vector Tiles in a @LeafletJS canvas layer. Works well! Also looking at @mapzen work!

@mappingmashups Jul 01, 12:17pm I mean, @jasondavies’s and @mbostock’s demos like jasondavies.com/maps/transitio… are unimaginable with raster mapping #geowebchat

@mappingmashups Jul 01, 12:19pm @apollolm Cool! What styling language are you using for your vector data in canvas? #geowebchat

@woolie Jul 01, 12:19pm #geowebchat I’m experimenting with Mapbox vector tiles to make interactive maps from census data.

@bohuang3d Jul 01, 12:21pm @mappingmashups Adobe Flash. Hehe me outcast #geowebchat

@apollolm Jul 01, 12:23pm @mappingmashups #geowebchat Brute forcing it now using regular canvas stroke and fill properties. Will use converter from nodeTiles soon.

@apollolm Jul 01, 12:24pm @mappingmashups #geowebchat Nodetiles github project uses a CartoCSS parser to convert to canvas styling…slick.

@mappingmashups Jul 01, 12:25pm @apollolm Interesting! I’m curious if CartoCSS will be able to evolve with the vector era? I know it won’t be part of #MapboxGL #geowebchat

@bohuang3d Jul 01, 12:28pm @mappingmashups @apollolm My understanding is dom elements using Canvas is not implemented with webgl right #geowebchat

@mappingmashups Jul 01, 12:34pm @professorlemeza @apollolm Is this the nodetiles project you’re talking about? github.com/nodetiles #geowebchat

@mappingmashups Jul 01, 12:36pm So, @mapzen’s vector rendering is built on @OpenScienceMap. (opensciencemap.org) Anyone here have any experience with that? #geowebchat

@allafarce Jul 01, 12:37pm @mappingmashups @professorlemeza @apollolm Aside, that’s the fine work of @codeforamerica folks @bensheldon @Mr0grog @yuletide #geowebchat

@bohuang3d Jul 01, 12:38pm @mappingmashups @mapzen @OpenScienceMap I love how the coast lines are rendered and wonder how it’s done. #geowebchat

@apollolm Jul 01, 12:40pm @mappingmashups #geowebchat yes, that is the project. In nodetiles-core/libs there is a cartoRenderer.js file. I think the logic is there

@mappingmashups Jul 01, 12:40pm @bohuang3d @OpenScienceMap Are you talking about the coastlines in the @mapzen demo? Can you share a screenshot? #geowebchat

@professorlemeza Jul 01, 12:44pm Only on Android. Web renderer is a new WebGL project MT @mappingmashups: @mapzen’s vector rendering is built on @OpenScienceMap #geowebchat

@mappingmashups Jul 01, 12:44pm Talking about styling languages, has anyone used #MapCSS? Looks like that’s what @GLMapFramework uses. Any better for vectors? #geowebchat

@bohuang3d Jul 01, 12:44pm @mappingmashups @OpenScienceMap @mapzen Perhaps vector.io/vector-map/#ma… #geowebchat

@professorlemeza Jul 01, 12:46pm @bohuang3d @mappingmashups @mapzen we construct a polyline outline around the coastline polygons and style those separately #geowebchat

@bohuang3d Jul 01, 12:47pm @mappingmashups @OpenScienceMap @mapzen These coastline as OSM Ways would span many tiles. Perhaps some processing to split? #geowebchat

@professorlemeza Jul 01, 12:49pm @bohuang3d @mappingmashups the geometry is simplified and split into vector tiles server-side mapzen.com/vector/ #geowebchat

@bohuang3d Jul 01, 12:50pm @professorlemeza @mappingmashups @mapzen And split the east coast polyline into the millions of tiles it goes through? #geowebchat

@mappingmashups Jul 01, 12:53pm @bohuang3d Could you start with some subdivided coast polygons like these? openstreetmapdata.com/data/land-poly… #geowebchat

@professorlemeza Jul 01, 12:53pm @bohuang3d @mappingmashups @mapzen oh, the coastline polyline is added as each tile is rendered client-side #geowebchat

@professorlemeza Jul 01, 12:54pm @mappingmashups @bohuang3d that’s exactly what we do! :) see mapzen.com/vector/ for details #geowebchat

@mappingmashups Jul 01, 12:54pm RT @woolie: @professorlemeza Is there a configuration to generate the entire set and cache as mbtiles for easier deployment? #geowebchat

@tmcw Jul 01, 12:54pm @mappingmashups @apollolm moving towards JSON-encoded styles. CartoCSS was built around Mapnik’s rendering model exclusively #geowebchat

@tmcw Jul 01, 12:55pm @mappingmashups @GLMapFramework the CSS metaphor for maps doesn’t have the same ring it used to + JSON tooling is far better #geowebchat

@professorlemeza Jul 01, 12:56pm @woolie @bohuang3d @mappingmashups I’m sure it could be, we are refreshing the OSM data daily and regenerating tiles on demand #geowebchat

@mappingmashups Jul 01, 1:01pm Well, we’re at the end of another #geowebchat. Thanks for joining, and enjoy the #worldcup game everyone!

@mappingmashups Jul 01, 1:03pm Next #geowebchat will be on July 15, at the same time. Topic TBD. See you all then!

@apollolm Jul 01, 1:03pm #geowebchat how is interaction with WebgL handled? Click events? Mouse over?

@bohuang3d Jul 01, 1:03pm @mappingmashups I think I’ll depend on Brett’s product ;). SenseEarth.com is more for fun and would love any solution. #geowebchat
