Data Import for Union County Georgia
Union County Georgia
Short Description:
Union County Georgia made part of the data public domain - out of that data the building footprints were most applicable to OpenStreetMap.
Data Description
The data consists of a shapefile with 27675 polygons. They were collected from Aerial Photography. Data already has address information attached to it in the form of:
- Number
- Street
- Street Suffix
- City and Zip were added after a discussion with the GIS Department.
- Data was delivered in projection of ESRI:102667
Conversion Plan:
Data will be converted to OSM. Street and Street Suffix will be combined. Fields will be matched to:
- Address:housenumber
- address:street
- Address:city
- Address:zipcode
- Address:State will be added.
Buildings can also be further broken out into residential and commercial due to some attribution by the GIS department.
Data Upload:
- Union County has been devided up into 83 grids of 2 square miles apiece. Data will be uploaded manually in JOSM by grid and checked against features in OSM. *An attempt will be made to contact any local active OSM mappers to let them now what is going to occur.
- The two smallest grids will be uploaded first to check for any errors. Any errors will revert in a revert of the changeset.
- There is a tremendous amount of bad landcover/tiger/nhd in the county - that will be cleaned up as the import continues.

OSM Community:
- During this upload I will be attempting to engage the local community to become more active. The GIS Department has shown interest and releasing this data is a huge step.
