OpenStreetMap
While not having done many GPS- traces recently I thought I could draw some forests in Potlatch - it makes the slippy map so much nicer and is a valuable tool for navigation. The best thing is that you don't need a GPS to do it.
Please have a look at the map north/ west of Salzburg (Austria) to view the results of my efforts.
Fortunately the Salzburg area has hires Yahoo imagery, but I think tracing around woods should also be possible with low resolution images and a little bit of local knowledge.
So if you have some time to burn- map forests...
Cheers,
Christian

I've been adding woodland and forests around my area here: osm.org/?lat=51.123&lon=-0.163&zoom=11&layers=B00FTF it does make the map much prettier I think, and is useful for off-road navigation. I find that it can sometimes be hard to decide where to draw the edge of woodland where the trees gradually become less dense and/or smaller.
