[HOT] [OSM-talk] HOT Activations for humanitarian relief

Thanks for your response. I think the area in question is under control 
now. The validation errors I found were for a road that was duplicated 
between my work and the previous stuff. But once I fixed that and maybe 
one or two other things the sector was clean. Someone seems to have 
backed out most of my overlaid entries already -- I'm not sure.

Anyway, how it happened: I click on the JOSM button and nothing happens 
in JOSM. The web page shows a link to a .osm file, so I do an Open 
Location in the JOSM file menu using that link and get the task square 
in JOSM. That first task, I started mapping from there. Naturally I got 
a big warning when I tried to upload (I don't understnad the details), 
but I had invested an hour or two of work at that point and didn't want 
to throw it away.

I hadn't looked at the existing Homs map before I started, or I would 
have realized that there was already data to be had. I found that out 
when I brought up the map to check out the results of my work. As a 
result, for the subsequent tasks, I imported the .osm file as above, but 
then proceeded to download from OSM in the JOSM File menu as usual, 
using the task square already there. That worked. The downloaded data 
came in a new layer (plus the GPS trace layer).

I'm sorry to cause extra effort on someone else's part -- probably the 
very hard-working Divjo.
