[Imports] [Imports-us] SNAP Retailer Locator

[Yury Yatsynovich]

Thanks for all your feedback!

As to Femont, CA -- indeed, I've started uploading the results, but, as one
could have noticed, it is done at a pace of ~1-2K buildings per day, after
manual edits to location/shape of each building, so the import is mostly
manual, not automated. With this pace it might be completed within 1-2
months. I'll update the documentation appropriately after it is finished.
True, sometimes errors like a temp tag "DONE=Y" get into the uploaded data
-- my apologies for this! By now I've already removed this temp tag and
will try not to make the same mistake again.

As to the retail locator -- the points in the SNAP data are, indeed,
located next to corresponding streets rather than on actual buildings. The
discrepancy between the SNAP points and the actual location of stores isn't
too large (10-30 meters for the points near my location that I checked),
but still not good enough for automatic import. I would do the import (if
the license permits) for MA by matching addresses of imported points to
addresses of OSM buildings (as MA has addresses added to many buildings),
rather than using only lat-lon of the SNAP points.

Thanks again, I appreciate your time and attention!

Best,
Yury
