For the past weeks I've been using public domain maps in mapping roads in Mindanao.
osm.org/user/maning/diary/951

Now most major roads are visible in the map.

osm.org/?lat=7.54&lon=125.3&zoom=8&layers=B0FT

3 tags are added: highway, FIXME and source.

I have a rough documentation on the process (will add more detail in time).
osm.wiki/index.php/OSM_Philippines_Data_Import

Overlaying ways on LANDSAT, I'm not really satisfied with the results some ways are way off by tens of meters. But the general geometry is OK. I will be editing further using landsat. Is there any way to cache landsat for offline JOSM editing?

cheers,
