[OHM] Building Infrastructure for OHM ­– RPA Historic Wetland Mapping

[Albin Larsson]

Maps Warpers mask feature can deal with those map borders ;-)

Here is the OHM instance of TM:
https://github.com/Abbe98/osm-tasking-manager2/tree/RPA-wetlands

Everything should be working except, making queries directly to OHM using
the Overpass Turbo link, it's possible using some data setting in the URL
but I haven't used it recently. Some string could say OpenStreetMap in some
places to but most of them should be right.

For OAuth I created an app "RPA - Wetlands" it's "Main Application URL" is
set to the Github repo but as far as I remember this won't be an issue at
least not when running it locally.
