[Talk-us] Available Building Footprints

California has more than triple the amount of data available than any other
state. Importing it will be no small task but doing it in chunks by several
people will make it manageable. The buildings in the Bay Area alone in the
file stretch from Clear Lake way down to Hollister and run along the coast
in Santa Cruz all the way up the East Bay. Several other large cities and
areas are included in the data. There have been several imports of
buildings here in California and many people have put in a lot of work
tracing individual buildings. This data will tie in those imports and will
be a valuable addition. I broke the data apart further by region along with
the status of buildings in the areas on the main wiki page at
https://wiki.openstreetmap.org/wiki/Available_Building_Footprints, and
there is a place for users to express interest. I would love to hear
further thoughts on this data set particularly on the data in California.
All the best,
Nathan
