Google Maps is no longer a flat map
- rm_-rf_slash 8y agoApple Maps used to do this too. They took it away a few versions ago for reasons I don’t quite understand. I really liked the “Pale Blue Dot”-like overview of the Earth when zoomed out all the way.
- nothrabannosir 8y agoApple Maps (desktop version) still does this, but only in Satellite mode. Which feels very intuitive, to be honest.
- ISL 8y agoOf course, the definitive pale blue dot image was not taken by a satellite, but rather a spacecraft on a hyperbolic trajectory.... ;).
- andrewaylett 8y agoI find it curious that it loads the old 2D representation first -- made me think it wasn't working for a moment or two. Also, is it just me or is zooming a bit broken at low zooms now? The globe drifts as I zoom.
- Bud 8y ago"On flat maps, it’s impossible to represent land mass size on a relative scale." Um, no it's not. TechCrunch needs better editors. You just need to use a non-Mercator projection. https://en.wikipedia.org/wiki/Gall%E2%80%93Peters_projection https://en.wikipedia.org/wiki/Gall%E2%80%93Peters_projection
- astrodust 8y agoYou can represent size or shape correctly, not both. Anyone who uses the Gall-Peters projection is a cop.

- hackme1234 8y agoYour username is obsolete in Ubuntu. It simply gives an error message.
- Ajedi32 8y agoGoogle decided to go with "A Globe".
- deathanatos 8y agoAt low zoom levels. Given the behavior of the poles (they're not viewable; the south is also a black hole…), I suspect that there's a very smoothly done transition to web mercator for the higher zoom levels.
- gefh 8y agoCorrect. At high zooms, the trig required in the spherical math becomes inaccurate, so we fade back to simple web mercator.
- astrodust 8y agoCartography wouldn't be able to use all these cheap tricks if the poles were habitable territory. Can you imagine the distortion on a map of a small town located at the pole if Mercator was used?
- sp332 8y agoYou can get pretty close though. Like a Dymaxion map (shown in sibling's XKCD link) or one of those orange-peel maps if you have enough little slices. Edit: better Dymaxion link https://en.wikipedia.org/wiki/Dymaxion_map https://en.wikipedia.org/wiki/Dymaxion_map It's made of triangles that you can rearrange, which isn't really shown in the xkcd.
- jbob2000 8y agoThat's still not an accurate map. 3D maps don't have projection issues, they can have near perfect representation of the world.
- jacobolus 8y agoThe eyes see a 2-dimensional picture. Computer displays produce a 2-dimensional picture. There is no such thing as a “3D map” on a standard computer display. Only an orthographic (or maybe perspective) projection which animates in response to user input. In general an orthographic projection is a poor choice. The thing going for it is that it is easy to understand by analogy to a physical globe, and human spatial understanding can partially compensate for the distortion by imagining a sphere. But there are also disadvantages, for example on an orthographic projection north is not always vertical, latitude and longitude lines are neither perpendicular nor straight, shapes and areas can be very dramatically distorted near the edge of the map, there are dramatic distance errors between far away points or points not in the center of view, it is impossible to view more than half of the planet’s surface in one view, etc. There are many other choices of map projections, and for any particular purpose, some other projection is usually better.
- mikeash 8y agoRegardless of what the eye sees, the brain perceives three dimensions. This projection happens to be the one that the brain can automatically unpack into an accurate 3D representation. Technically, things near the edges are squished and distorted, but that gets undone in the wetware.
- jacobolus 8y agoYou really can’t get an accurate sense of angles/shapes, areas, distances, or directions with an orthographic projection except by moving the view around. Even when you do, it is very difficult to accurately compare attributes of regions which are far away on the globe, and easy to mislead yourself. (This is a problem with physical globes as well.) For many types of mapping use cases, orthographic projections are substantially worse than other possible choices. Sometimes physical spheres (or virtual representations of spheres as dynamic orthographic or perspective projections) are nice. That’s why I spent a whole bunch of time building myself a spherical chalkboard, for example. But they aren’t the best choice for any purpose. Personally I don’t think they make a very good choice for a general-purpose world map. They are better as a supplement to flat maps.
- nikofeyn 8y agoit's a theorem of differential geometry that we cannot have a (perfectly) accurate 2d map of the earth.
- mrb 8y agoThe author of TFA didn't write "perfectly accurate" but "land mass size on a relative scale". Bud is correct.
- nikofeyn 8y agothe author of TFA probably thought the desire for correct shape in a map is implied and wasn’t trying to defend against map pedantry. of what use is a map if the shapes are wrong?
- kccqzy 8y agoOne of the revolutions in the first Underground/Subway/Metro maps was that by throwing away the actual shapes, it is able to represent the stations and the relationships between them far clearer than otherwise.
- nikofeyn 8y agoa subway map has little to do with a geographic map. only the nodes and time traveled between them matter. the shape of the actual routes is immaterial.
- hackme1234 8y agoFrom the first line of the article. The Gall–Peters projection is a rectangular map projection that maps all areas such that they have the correct sizes relative to each other. Like any equal-area projection, it achieves this goal by distorting most shapes.
- rorosaurus 8y agoIt's much cheaper to make an incorrect statement and let people correct you for free, then edit the article! ;)
- pmilla1606 8y agoLooks like this isn't rolled out to everyone. I'm not seeing the 3D version (logged in & incognito).
- sergers 8y agoon my work computer, which is tunneled through san francisco, so i show as in USA, i can see the 3D map. checking maps on mobile which is on Canadian ISP, in chrome and the google maps android app, i can only see the "flat" map.
- senozhatsky 8y agoThanks. I thought it was a "browser thing". My desktop firefox shows flat maps only. -ss
- sergers 8y agoi can confirm that chrome, firefox and IE browsers show the new view with my location as USA only.
- sdinsn 8y agoI don't see the map either (and I'm in US).
- gefh 8y agoFor rollouts like this, a small holdback experiment is typical, to assess long term trends. Or maybe your browser doesn't have hardware acceleration enabled? Or you could be in canvas mode? Try ?force=webgl on the end of the maps url in case it's the latter. Try shadertoy.com to see if webgl is available.
- sigmar 8y ago>On flat maps, it’s impossible to represent land mass size on a relative scale. This isn't right. It is impossible to represent both relative position and relative size accurately. Gall-Peters and other equal-area projections accurately represent relative sizes.
- rspeer 8y agoThere are cartographically reasonable equal-area or nearly-equal-area projections. Why are we still talking about Gall-Peters? Peters was a charlatan who knew very little geography (he didn't even want to give credit to the geographer who discovered his map), and the Gall-Peters projection is Mercator for old-school hippies who think they can promote equality by making Africa taller.
- euyyn 8y agoExpand?
- lainga 8y agoYes, but only vertically.
- euyyn 8y agoI was trying to ask the parent to expand on the many things he was claiming lol
- rspeer 8y agoHere's a couple views on Peters and his map projection. An article from "The Map Room" [1] on the argument about Boston public schools having adopted that map, which really dominates Google results right now I guess, but even within the lens of that topic it hits the major points. And here's a "New Internationalist" article about Arno Peters [2] -- it sounds like he was fine as a historian, and I even agree with his motivation for not wanting to plot historical events on a Mercator map, but it sure would have been great if he had learned about the equal-area alternatives to Mercator that Gall and Mollweide and Eckert and other geographers had already made. It's not that I'm against making a map projection to "question Western imperalism". I take more issue with Peters' questioning of basic geometry -- he claimed his map preserves angles, which is clearly false (imagine a NW-SE road meeting a NE-SW road in Ecuador and what that right angle would look like in Gall-Peters), and he claimed that it was the "only" equal-area projection. And I don't think it actually advances the conversation about equality to make a map that looks right in Europe and stretches Africa and South America like taffy.

- SiempreViernes 8y agoFinally we are rid of the biggest source of Mercator! Finally we can look at the south pole!
- SiempreViernes 8y agoActually no, McMurdo remains a white sport still :(
- MattBlissett 8y agoThis is an unfinished demo from a while back, but I made vector and raster map tiles in a WGS84 projection, so McMurdo is included — though you have to find it yourself [1] I'm unlikely to work on the globe, it's cool[2] but we don't really need it. Maybe when OpenLayers Cesium[3] gets support for vector tiles, so we don't have to see fuzzy, distorted raster tiles.

- jpindar 8y agoI can see a lot of individual buildings there, and I can see facets on the dome. There's even Streetview!
- cup-of-tea 8y agoUnfortunately not. The behaviour at the poles suggests that the whole thing is merely a hack.
- dougmwne 8y agoI wonder what the long term geopolitical consequences will be when we all stop looking at projected maps. That small peninsula to the west of Asia just got a little smaller. A certain island kingdom is now more clearly the size of Uganda. Maybe Google can also flip the globe "upside-down" for all users "below" the equator.
- SiempreViernes 8y agoThere is something weird going on near the poles still, so I'd not be surprised if its technically expensive to make an "upside down" map. Upside down and mirrored should be simple though.
- jerf 8y agoDo we really think very much is really affected by map projections? Korea looms large in people's imaginations for a lot of reasons that have nothing to do with its occupied land mass size, and a lot to do with their history and cultural and economic power.
- Theodores 8y agoIf Korea is not occupied by the U.S. and allowed to unite then it would take a decade or so before their economy would be number two in the world with them kind of needing to be on the U.N. Security Council. The same can't be said about if Sudan was united again, Sudan would not be magically punching above India, Russia and Germany in international commerce. The world where we see the world as it is, a sphere that we can interact with and with that sphere being the default view has been a long time coming. We will look back and wonder why we got the perspective wrong for so long. There are no other objects we display in Mercator Projection et al. If we could go back in time with what the fine people at Google have achieved and give it to navigators of the past, in the days before aeroplanes got popular, then all the hacks that 'demand Mercator' would never have arisen. Maybe we would have to teleport GPS back to this fictional past too. The none-sphere maps make as much sense as those paintings done before perspective was worked out, we have just ended up believing them out of familiarity and due to the navigation and other hacks devised for the atlas makers of the past. As recently as twenty years ago the idea of just showing the earth as a sphere for things like weather broadcasting would have seemed a radical and controversial idea. Thanks to Google and de-facto Maps we have made a small but important evolutionary leap in understanding our world.

- JorgeGT 8y agoThe visualization is really cool but for daily use seems more practical being able to plot long trip routes without them disappearing on the back of the globe than being able to assess the true size of landmasses: https://www.google.com/maps/dir/Madrid/Sydney,+New+South+Wales,+Australia/@23.2935702,-5.1637745,3.36z/data=!4m14!4m13!1m5!1m1!1s0xd422997800a3c81:0xc436dec1618c2269!2m2!1d-3.7037902!2d40.4167754!1m5!1m1!1s0x6b129838f39a743f:0x3017d681632a850!2m2!1d151.2092955!2d-33.8688197!3e4 https://www.google.com/maps/dir/Madrid/Sydney,+New+South+Wal...
- bla2 8y agoI get what you're saying, but I'm not sure if planning trips to the other side of the globe qualifies as "daily use" either :-) I think it's neat to see that the route is along a great circle -- that wasn't clear at all before this change.
- JorgeGT 8y agoMillions of people do it everyday, so it seems right to call it daily use: https://twitter.com/flightradar24/status/1018260113814061057?lang=en https://twitter.com/flightradar24/status/1018260113814061057...
- brandonhorst 8y agoUnfortunately, the line drawing doesn't make this as cool as it could be. The line representing the flight from BOS to PEK is drawn due west, as would look natural on a 2D map. The real flight (and shortest route) heads north and passes near the north pole. Hope they can update this, which would make international flights seem even more impressive than they already do.

- dilap 8y agoVery cool! It's always seemed a shame to me that we stick with highly-inaccurate projections when we have the tech to do much better, simply out of inertia. Double-cheers as well for ignoring the weird convention that you shouldn't care about accurate sizing when looking a political rather than satalite map.
- jld 8y agoIf there's a job where I just get to explore the wonder of Google Maps all day, I want it.

- barryp 8y agoVery cool. However it's not using great circle routes for airline directions, for example ask to go from Calgary to London. It should go well over Greenland, but instead just follows the same path you'd get from drawing a line on a Mercator map.
- mjg59 8y agoEastbound flights often take non-great circle routes in order to make better use of the jetstream - depending on the forecast, a straight eastward line may be more accurate than a great circle.
- seanalltogether 8y agoWeird you're right, however if you use the measure distance tool it does follow the curve correctly.

- phyzome 8y agoBy the way, for anyone who prefers Google Maps to load fast and show actual satellite/aerial imagery (rather than trying to render each tree as a weird crumpled blob) there's a flag you can set to get the old, fast 2D mode: https://maps.google.com/?force=canvas https://maps.google.com/?force=canvas
- dysoco 8y agoThat does seem to show older images though.
- chch 8y agoAgreed, the images do seem lower quality than they used to be. I was curious, though, and chose buildings at random around the Google office in NYC, just to do a side-by-side, and even the old pictures look better: https://i.imgur.com/0xEG4pb.jpg https://i.imgur.com/0xEG4pb.jpg https://i.imgur.com/bxwr3Ez.jpg https://i.imgur.com/bxwr3Ez.jpg

- Sohcahtoa82 8y agoThank you! I'm actually quite annoyed that Google took away the visible option to disabled the 3D aerial view. It's such a resource hog, and my work's internet is often quite slow, and 3D has far more data to retrieve.

- krotton 8y agoAnd interior of the ISS :). Thanks, that was a fantastic journey!
- pseudonym2 8y agoSo it's no longer a map application, because it's producing weird non-standard projections, tiles that can't be stitched/georeferenced properly etc. Will Google support and maintain an actual maps application? Or will they merge google earth and google maps together in an even less capable tool purely for consumers to wow at? Castrating Google Earth with the webgl version and locking it into Chrome was bad enough. I wish this stops here.
- CommieBobDole 8y agoGoogle Earth desktop edition is still available. And it's still approximately ten thousand times better than the browser edition. https://www.google.com/earth/download/gep/agree.html https://www.google.com/earth/download/gep/agree.html
- pseudonym2 8y agoIt's gradually phased out. Right now it's essentially abandonware. At some point in the future they'll just kill it out of the blue. Things that provide value to advanced users don't matter to most of these "data-based" companies.
- modeless 8y agoPerspective projection is not weird or non-standard. In some sense you could consider it the least weird projection, since it's what your eyes actually see when looking at a globe. But if you just can't get enough of Mercator, the option is still there in the hamburger menu (labeled "Globe").
- martijn_himself 8y agoGoogle Maps must be one of the modern wonders of the world, it's still nothing short of breathtaking to zoom out of streetview in crowded London and then land somewhere on a country crossroads in remote Vietnam.
- rococode 8y agoAnd once you land on those country crossroads, you can continue exploring the area at the street level. It's really an incredible tool for sating wanderlust - just pop over to some place you've wanted to visit and wander the streets via streetview, all from the comfort of your seat! Speaking of which, GeoGuessr [1] is a great example of how to enjoy Google Maps. You start at some random streetview and try to figure out where in the world you are by walking around (and hoping to see a sign or two)! A lot of times you end up in dirt roads in small countries, and it's really cool to see what it looks like there. [1] https://geoguessr.com/ https://geoguessr.com/

- criley2 8y agoIt'll be an interesting thing. They definitely understand the gaming angle due to Pokemon Go causing them to specially create tools and customize their API for gaming: https://cloud.google.com/maps-platform/gaming/ https://cloud.google.com/maps-platform/gaming/ But that seems to be Enterprise level only. They seem to have already updated for the new level. They also have advertisements and are a profitable business. My guess is that they "Contacted Sales" like the Gaming API asks you to do and have a very agreeable discounted rate.
- puzzle 8y agoThis was going to launch years ago with the vector rewrite, but it was only enabled for the globe mode (Earth/GL, complete with a simulation of the objects in the sky). Interesting timing.
- weka 8y agoI am honestly surprised how Google has not released a GPS navigator to compete with TomTom or Garmin. It would absolutely demolish them in seconds.
- kemitche 8y agoThey already have: the smart phone in everyone's pocket.
- Animats 8y agoIt never was a flat map. That was just a kludge to make it work in the browser. The original application, from Keyhole, was 3D from 2003 or so. NVidia used to offer it as a promotion, before Google bought it. Now it's a Chrome browser promotion. Google Earth requires Google's browser.
- unethical_ban 8y agoGoogle Maps.
- huangc10 8y agoJust a note, they also changed how navigating works. It's almost as if the map curves differently at different zooms. The physics is very cool but it is a little nauseating. It is very realistic, almost like spinning a globe, but I'm not sure if its more preferable.
- mshaler 8y agoBut time is still a flat circle.
- robius 8y agoWhile this is a great improvement, this is most needed on mobile devices. This was especially a problem with Ingress and Pokemon Go games where you need the map to be correct where it isn't. Even more difficult is using those apps in places like the Arctic or Antarctic, there's no way to accurately place GPS coordinates, deal with game portals or have directions other than the compass.
- lxe 8y agoDid the compass disappear? I'd like to still be able to rotate the map.
- Hello71 8y agoI believe this makes Google Maps the only mainstream SaaS map providing orthographic projection, and I wonder if that (partially) explains the recent increase in Google Maps pricing (previously: https://news.ycombinator.com/item?id=17570029 https://news.ycombinator.com/item?id=17570029).
- outworlder 8y agoI am always amazed to see how ridiculously huge the african continent is. There are really huge countries over there.
- DoctorBit 8y agoA couple of suggestions for improvements: 1) Use quaternions instead of Euler angles for rotation 2) Show latitude and longitude grid so it's easier to identify equator and polar regions, etc...
- nojvek 8y agoLangitude longitude grid would definitely make it easy to map it to the flag mercaretor projection. One can easily also correlate why things on the pole look so big when you have evenly spaced latitudes in a sphere.
- Groxx 8y agoAs neat as this is, it's kinda a crummy experience in a few expectation-breaking ways :\ Most notably perhaps: if you put your cursor on a spot on the globe and scroll, you don't zoom there. You zoom somewhere in between. Mostly things that can be fixed in the future (except perhaps "requires multiple click-drags to go to the opposite side", where before you could see most/all of the world at once). But it still seems a bit more shiny than useful.
- vinayan3 8y agoThere is a really good short youtube video about map projections and to understand the tradeoffs that are made to create them. https://www.youtube.com/watch?v=kIID5FDi2JQ https://www.youtube.com/watch?v=kIID5FDi2JQ
- nojvek 8y agoWhile I was working on the PowerBI globe map visualization https://powerbi.microsoft.com/en-us/blog/visual-awesomeness-unlocked-the-globe-map/ https://powerbi.microsoft.com/en-us/blog/visual-awesomeness-... (video in link) I had to do some funky magic to stitch square tiles in a sphere from bing maps and do reverse mercerator projection. I had to also ensure GPS coordinates would exactly align to the right pixel otherwise the 3D chart would all look weird. So there was a lot of fun math involved over a bunch of evenings and weekends. The hard part though, was to do an animation that would unravel a spherical earth into a flat earth and vice versa. Naive me though it would be a simple linear interpolation that would take a couple of minutes but it ended up being many many nights of crazy mathematics to get it right. Map projections are really interesting. Much respect to their inventors.
- kccqzy 8y agoI'm interested in learning more! I imagined linear interpolation could work too. What went wrong?
- nojvek 8y agoThis does a hemisphere but doesn’t map lng and lat. Gives an example of the kind of maths involved. https://math.stackexchange.com/questions/1334241/interpolate-between-3d-plane-and-3d-hemisphere https://math.stackexchange.com/questions/1334241/interpolate... It’s not a simple linear x0, y0, z0 -> x1, y1, z1 because you kind of want an animation like a square blanket is wrapping around a ball, stretching the right amount in different places such that it becomes a sphere. I tried to find a single magical equation that would give a x0, y0, 0 -> x1, y1, z1 based on param t that goes from 0 - 1. I’m sure there exists one but I tried all sorts of fancy math I knew for a day or two and still had major trouble writing it down as a single equation function. Then I thought about it in a different way after I ate a fruit and realized I need an orange analogy. What if we cut slices of orange. The ends are crescent shapes. Now it’s a matter of animating the crescents into rectangular strips where the pointy ends stretches but the middle part remains the same. Since in computer graphics, a sphere isn’t really a true sphere, but an approximation with triangles the strip analogy works well. We just need to animate the ends of triangles. The gotcha is the pointy end of sphere expands from 0 to length of mercerator projection (flat square) so they cut a tiny bit of the top and bottom otherwise you have infinite stretching at the end So you have three little functions. For an x,y in a square you figure out what slice they go into and what side of the slice. The further to the poles, the more you squeeze towards the center, so you get something like this https://blenderartists.org/t/producing-a-12-petal-gores-from-a-uv-projection-sphere/637809 https://blenderartists.org/t/producing-a-12-petal-gores-from... Then you have a blanket wrapping function I.e morphing a line into circle and that’s a line -> arc -> circle animation. That’s not too hard. The arc of a very large circle is almost flat. So you divide the line into two and animate the left and right segments into two hemicircle arcs that then form a proper circle. Kind of like curving the lines from the end to bend it into a circle. Now longitudes and latitudes both go through this line to circle animation. To get the z, we take the x arc position, the y arc position, the point on crescent strip and we do matrix rotate transforms to get final x,y,z So rather than it being one single equation (which i’m guessing is possible using super crazy maths), we take a piecemeal approach and animate lots of little segments that add up as a plane to sphere animation using simpler maths and matrix transforms.

- Kagerjay 8y agoWhat's really interesting that in 2D maps, every country had their own variation of it. If you were to take a 2D printed world map from America and compared it to a 2D printed world map, the sizes of continents wouldn't be the same, nor the centerpiece of the map itself. It would always center around that respective country first.
