I edit Gillette, Wyoming, USA and Campbell County, Wyoming, USA. I welcome suggestions and changes to the map in the area. I generally follow the guidelines in the OpenStreetMap Wiki and regional norms. In Gillette, I’ve seen it, photographed it, know about it, or have it on dashcam.

Editing OpenStreetMap

• OWL Map — Helps to link Wikidata and OpenStreetMap data.

• Rapid Editor — Microsoft Building Footprints are good for quickly creating rough drawings of buildings. Search for and add the Department of Transportation to add addresses. All the addresses must be checked and fixed to match the actual street names.

• Geographical Names Information System: search — GNIS removed many features in 2021 so many of the GNIS numbers in OpenStreetMap are no longer valid. Is still useful and should be checked.

Editing Gillette and Campbell County

• Census of Agriculture: Campbell County — 91% of farmland in Campbell County is pasture, 6% crop, and 2% woodland. Almost all of the land use is for hay which makes those areas a meadow in OpenStreetMap. The rest is wheat, barley, and oats, which I suspect is also used as animal feed. There are almost no farms. Everything is ranches and the land is either open grazing or used for hay bales.

• Campbell County property records — Has street names and subdivision names. Can differ from TIGER or the DoT street names.

• National Inventory of Dams: Campbell County — Some of the dams listed are actually dikes according to OpenStreetMap’s definitions.

Land use - Campbell County land use is mostly ranching ( landuse=farmyard , landuse=meadow ), coal mining ( landuse=quarry ), oil wells ( landuse=industrial ), and CBM or coal-bed methane wells ( landuse=industrial ).

Dams and reservoirs - The county has many dry creeks ( waterway=stream and intermittent=yes ) with what we locally think of as stock ponds ( water=reservoir ). OpenStreetMap defines them as reservoirs because the ranchers completely block the creeks and it enlarges the stream when blocked. The dams ( waterway=dam ) are often little more than a small hill of dirt, but it’s enough to block the creek.

Private roads - Driveways and service roads in the county and city are not marked access=private unless there is an actual sign that says so and I add the sign in the notes. Exceptions are when the only road leading into it is private such as the coal mines behind the guard shack ( building=guardhouse ) or all the driveways behind a residential road with a sign saying private property.

check_date - I try to add check_date=* to all businesses. This is to keep track of the last time someone verified it was still there. Businesses in Gillette come and go quickly, especially in the strip malls.

Unmarked crossings - Unmarked crossings can be excessive in Gillette. That is because there are more curb cuts than roads. It can be so excessive in some spots there are more cuts than actual sidewalk. Also, there are many unused and left over cuts everywhere.
