Hi imports@ list,
The SF building height import team is working to add height data for
buildings in the City of San Francisco (wiki ). We'd like to revive
the discussion which was started back in May . We now have a newer,
higher resolution height dataset from the city government released
under a CC0 license .
We've added some new sections to the Wiki () detailing our methods
and evaluating the data's accuracy.
We're assigning heights by matching the new building dataset with
existing OSM footprints (within 70% match) . To respect the work of
local mappers we're not deleting or adding any new buildings, nor are
we replacing any existing tags - we're only adding heights where they
don't already exist. This import process will have manual oversight at
The data is available in this Tasking Manager for everyone to review:
Please review, but don't upload. Feedback is always welcome! Please
comment here, on GitHub  or chat with the team in Gitter .
