Maybe someone is trying to steal the name here by deleting and readding things at the same time. They have similar profile descriptions almost can be identified as fake/illogical. They share similar behaviors and may even be able to write a diary.

However, they have received blocks in the history:

osm.org/user/NorthwestPAmapper (we caught this account churning in Maryland by deleting a whole shopping mall with surrounding area and failed to readd back after 3 days).

osm.org/user/theurbanexploringman

osm.org/user/buildingroadfixer12

osm.org/user/ZenithTheFox

osm.org/user/Jakethedog2004

I assume that some laymen residing in that area are willing to join and improve the project, but the repeated similar behaviors prompt me to believe that it is abnormal.

If anyone above thinks that you are being offended, please reply and tell us why you keep churning. Seriously speaking, I wish to know the benefits as well!

This entry will be constantly updated based on my findings in USA.

Please be advised that a correct solution depicted below is not the only one. You are welcome to brainstorm in the comment section!

The reason why the intersection originally looks like this is to prevent reckless driving in rural area.

People should be wary of the imagery offset especially using high resolution products. In OpenStreetMap, Mapbox often provides high resolution images in densely populated areas within the US. However, just because Mapbox provides high resolution imagery does not mean the offset is not a thing. In fact, Mapbox has created a lot trouble as it pretends to be accurate but actually not.

Keep in mind that whenever your local municipality has its own orthoimagery published, always use it to draw features (of course it has to be compatible with OpenStreetMap, if it is missing in iD, maybe you can bring it in). The imagery could be dated, but it is accurate. Your local municipality will spend more time to process with the data. These “commercial” providers, like Mapbox or ESRI or Bing, do not have a lot of time to carefully examine everything in a specific area especially when it is not that popular.

I’m going to post an example here. The orange area is OSM data fetched by QuickOSM in QGIS, drawn by a random person who has not noticed the offset for years.

Cosmetics changes

Usually happen when the changes are mostly related to cosmetic features, like road realign, water features realign, tag upgrade, field upgrade, traffic sign upgrade, business details…

[Township/Town/City/County][State] cleanup (e.g. DuBois PA cleanup)

Related to changes within a specific area. Could be any type of changes.

[Township/Town/City/County][State] speed limit updates

Related to speed limit updates, could be multiple roads within a specific area

Add a chimney/Add a water tower/Add a building

All these features were added for mapping cell tower. My focus will never be buildings in this project.

Junk Removal

When I really cannot stand the crap (mostly complex relations) in the map so I delete everything and start from scratch.

Sometimes could be reverting others’ “contribution” (damage)..
