In 2016, San Francisco city Government published LiDAR-derived building footprints that include both geometry and height information. One of the main goals of the San Francisco OpenStreetMap community was to import this height data to the existing buildings in OpenStreetMap. The project was initiated by SF community in November 2016, recently Brandon and Daniel lead a great Mapathon at Mapbox SF office.

Together with the community, Mapbox data team remotely joined and imported nearly 140,000 building heights to OpenStreetMap. Now we can get a real world like experience using popular 3D renderers like OSM Buildings and Mapbox GL JS or create realistic city using Blender or style buildings using Unity. Cheers to the all of them who made this project successful!

We will be validating these buildings through street level imageries. Both Mapillary and OpenStreetCam have great coverage in San Francisco City.

OSM/Mapillary comparison tool:

Right now we are using comparison tool to validate these buildings heights. Here are the detailed instructions to validate these buildings.

Please get in touch with the community in the Gitter channel for validation and for other updates.
