9M buildings in 3D, 🙇 MS

Posted by Chetan_Gowda on 14 June 2017 in English (English)

Microsoft recently released 9.8 million building footprint data of 102 cities covering 44 US states to the OpenStreetMap community. This is a huge boost to improve the building data in many parts of the United States. Right now, we have ~ 19 million buildings already added by the community through imagery tracing and imports.

The most exciting part of this data is that all the footprints have height information. That means we can generate simple 3D buildings. I downloaded all the data and created a Mapbox style with 3D extrusion:

Philadelphia (live map) Boston (live map) Baltimore (live map)

In general, the data is of good quality and will improve the building coverage in the US by 150%. But the quality may vary from city to city. Local mappers should evaluate each city before deciding to import. If anyone wants to visualize the data in Mapbox Studio, you can use this tileset*.

Feel free to play with data, post your findings or screenshots of the data evaluation for the city you are interested in and let the community know how valuable this data is going to be for OpenStreetMap.

Code and other steps is available in GH repo:

* California not included in the tileset since OSM has fairly good coverage

I tried to compare the look of OSM and the live map, but it (yet) looks quite diferent.

How did you assess the quality?

@Nakaner, I loaded a city (Mobile) data into QGIS, compared with the existing buildings and MS data. Look good for me! But love to hear from the community on quality for another round. More eyes more accurate it will be and easy to import.

@-karlos- Thanks for reviewing. Yes, this location looks quite different. It’d be good to check more cities, compare and post your findings/screenshots here.

Well, the Microsoft data can’t be as detailed as OSM, of course. No roof types, no building:parts. If MS-buildings are unique, they could be imported. There are certainly a lot of unique height to be imported. You should find help about importing from expirienced users. May be a MapRoulette could be useful when data are not clear.

You may compare the “live map” with osm. The 3D rendere are listet here:

Oh yes this is spam. Would like to delete that if I have permission to do it. @-karlos- anyone help me to delete the spam comment.

How does one use Studio to view your Tileset? There is no Tileset id I’m seeing when looking at your tileset page.
