[Talk-us] buggy buildings in Maryland

[Elliott Plack]

Here's a potential fix: use the SimplifyArea JOSM Plugin.
https://wiki.openstreetmap.org/wiki/JOSM/Plugins/SimplifyArea

The plugin is built for fixing over-noded and buggy imports.

As a test, I downloaded the plugin and then downloaded some of
Annapolis sailor's buildings.

This building should only contain four nodes:
https://www.openstreetmap.org/way/525751797

This building should only contain eight nodes:
https://www.openstreetmap.org/way/526209538

The plugin successfully reduced the nodes for both buildings without
affecting the shape, unlike the simplify way tool.

I tested it on a larger swath of 500 buildings and it took less than a
second to run.

I haven't uploaded any of the changes yet, but I think this would be a good
path forward.
