OK, I have the data in JOSM in the WGS84 projection as a GPX file. I
converted the GPX layer to a data layer. I then zoomed in to one small
distinct piece and selected all the nodes.
Next I went to the menu and choose Forest and entered a name for this
piece (Coronado National Forest). However the area wasn't shaded.
Is this the right way to do it?
