Union County Georgia made their buildings (as well as roads) accessible
through a public domain license - they've asked myself (rjhale1971) and
Carol (geocak) to upload them into OpenStreetMap.
So far:
* I added a row to the import catalog - but it appears to have
disappeared - so here is the page:
http://wiki.openstreetmap.org/wiki/Data_Import_for_Union_County_Georgia
. I'll add it back to the catalog.
* The building footprint data came with addresses that had already
been spatially joined (conflated) - so each building has an address
consisting of housenumber, streetname, city, and zipcode.
* Buildings had been categorized (churches, commercial, houses, mobile
homes, accessory) by the GIS department and I moved that to match
OSM tags.
* There are about 27000 building foot prints so I've divided the
county into a grid. Data will be uploaded and checked by grid - some
buildings do intersect the grid but it's a very rural area.
o This isn't a scripted import. Each grid will be checked in JOSM
and validated before it's uploaded.
o I pulled Churches and Schools out to add an amenity tag to
those. There are less than 70 polygons - they will be uploaded
outside of the grid method I've devised.
o We will be checking addresses against the highway name in OSM.
* Finally - I'll be encouraging the Union County GIS department to
interact with OSM more - they've expressed an interest in doing more
with it - as have other counties in the area. So I hope this is
spurs their involvement. I'm not encouraging them to upload - but to
edit and work with the map.
* Both Carol and myself will have a separate import account (in the
process of making that - It will most likely be rjhale1971_import
and geocak_import.
I would like to do a small upload to check everything at some point this
weekend - I expect the entire process to take a week or more if I don't
run into problems. If I do I stop and re-evaluate.
