Import Instructions
- 1: download an extract of the raw data within the bounds of the state/region that you are importing
- 2: remove all the tags that aren’t listed for importing. convert all the tags above into the OpenStreetMap tags. I recommend converting LocAdd to note to make it easier to review.
- 3: add these tags to all objects: source=HIFLD Cellular Database, communication:mobile_phone=yes
- 4: download a new overpass layer from OpenStreetMap in JOSM including with all objects tagged with man_made=mast, man_made=tower, man_made=communications_tower or man_made=antenna.
- 5: with both layers loaded, use the ToDo list plugin to review each object individually, add the correct structure tags (mostly man_made=mast, and tower:construction=*.) add the address data as well if you chose to include it.
- 6: If an object already exists on the OpenStreetMap database, preserve the history by merging the imported data with the existing node.
- 7: if one mast/tower has 2 different broadcasting antennas, add one man_made=mast node, and 2 antenna nodes, the applicable tags applied to each.
- 8: upload to OSM using your import account. make sure to include the link to the database page and this wiki page in the source of your changeset.
