Hi,

Recently we came across three open buildings datasets for San Jose[1],
Berkeley[2] and Fremont[3]. We have evaluated the quality of each of
the datasets and found them to have good coverage and building
extrusions match recent satellite imagery. We have updated the wiki[4]
with the above sources for California.


- San Jose: https://cloud.githubusercontent.com/assets/1933377/22969874/09901660-f396-11e6-93a9-225dfab1ccc9.png
- Berkeley: https://cloud.githubusercontent.com/assets/1933377/22469786/28cb43b4-e7f3-11e6-979c-0fcc27cea67d.png
- Fremont: https://cloud.githubusercontent.com/assets/1933377/22917071/97fb3536-f2a8-11e6-885c-26a5f0a6ce14.png

The datasets for San Jose and Berkeley also contain building heights
and that of San Jose contains building parts as well.

Our team would be happy to collaborate if you are open to importing
these datasets to OpenStreetMap.
