Fantastic project and front page. I'm sorry I have nothing to add, I'm just amazed be the effort, and how smooth, fast and straightforward it all is presented.

This is awesome! Did you know that swisstopo publishes a dataset of 3D models of many swiss buildings complete with accurate roof shapes?

I think version 3 is now in beta and last I checked they even covered remote areas and alp huts: https://www.swisstopo.admin.ch/en/landscape-model-swissbuild...

Very nice! Is there a way to upload GPC files?

That's sad, but maybe somebody will see it here and decide to maintain this very cool project!

Yeah, the OSM data seems really complete for some cities. Co-incidentally, I've recently been putting together some 3D GIS visualisation stuff using OSM data.

Try zooming in to pretty much any capital city, then use the right mouse button to rotate the viewpoint so the 3D shows up properly:

That's just a temporary domain and an in-development project, but (to me) it seems to be working pretty well. Can build applications on top of this.

Works in FF for me. It's rather resource hungry, maybe an OOM? Judging from RAM consumption I'm guessing it doesn't utilise GPU, but maybe it does and didn't fit in mine.

I'm in Chrome and I'm also stuck on a white view, probably because https://streets.gl/js/index.js cuts off halfway through

Same for me. I get the following messages in the console:

Loading failed for the <script> with source “https://streets.gl/js/index.js”. streets.gl:1:940 A resource is blocked by OpaqueResponseBlocking, please check browser console for details. script.js Loading failed for the <script> with source “https://analytics.streets.gl/js/script.js”. streets.gl:1:815

I get a CORS error in the console. And a WebGPU error in Chrome. This is a Linux Debian machine.

Same symptoms. Latest Firefox and (Ungoogled) Chromium on Linux, latest Firefox and Edge on Windows.

Me too. White screen on Chrome, iOS and macOS.

It does use elevation data, but does not exaggerate it, I guess. Back when I was working with 3D maps, we noticed that many people liked exaggerated terrain heights better, especially when the terrain is viewed from above and realistic heights looked “flat”. Near where I live it looks fairly close to what it does in real life: https://streets.gl/#48.50063,8.99766,7.25,312.50,135.56 (granted, having added building and roof colors for almost all buildings also helps).

the 4 story building I live in is rendered like a basement only dwelling which is actually growing on me the more I look at it ...

It's too keen to add windows. This also is a bit annoying with churches. At least garages and sheds don't get windows by default.

I pressed tab and it started working

All the initial assets yes, although once it started pulling in tiles, those seemed to be parallel from then on.

It took over 43 seconds to load for me according to Firefox's dev tools Network tab, each image was effectively > 300 ms, but I'm in New Zealand, and the server seems to be in the Netherlands, so that's almost worst-case...

OpenStreetMap has the building outlines (sometimes even parts of the buildings) as well as tagging that specifies

    • wall and roof color
    • wall and roof material
    • roof shape
    • height (or levels, which
      typically is then multiplied
      with 3 m to get a rough height)
    • starting height (or level), for
      building parts above ground, e.g.
      bridges between buildings.

This can then get rendered as upwards extruded polygons with a cap in the shape of the roof. There are a few more complicated ways of specifying complex roofs with ridge lines, etc. but few renderers support them and usage is fairly limited.

I think it must be using the building outline data (and metadata like the heights) that people have entered, because in my city the inner-city has very complete data but a bit further out, around where I live there aren't any building outlines on OSM and there's nothing in this 3D map apart from just the streets.

The result is very impressive given that seems to be the case!

Edit: There are some more details on the github about data sources: https://github.com/StrandedKitty/streets-gl

They have open street data on building height, and roof shape, which lets them render 3d shapes.

https://demo.f4map.com/#lat=-33.8564200&lon=151.2149210&zoom... f4map does a pretty good job, although I'm not sure if they use some extra model here or just render it based on osm data. Sydney opera house seems pretty well mapped and I think you could get something like that from it.

But definitely something similar can be rendered. Streets Gl handles complex shapes quite well: https://streets.gl/#52.23135,21.00506,45.00,0.00,1466.87

> How does stuff like that happen?

Simple: nobody entered the height of your condo building into OSM yet. You can change that. Be the change you want to see in the world!

What I find funny is that they picked tree models that have branches down to the floor. So any tree next to a road blocks at least one lane when its branches should be several feet in the air.
