[Talk-in] Mapping an area from a satellite view

[Guillaume Audirac]

Hello,

I would like to map areas (like the Kabini lake) from the Yahoo! Aerial
Imagery, but without sketching them manually (as I can do in Potlatch). I
was thinking using Gimp on the satellite view to extract an outline and to
import it as a way, somehow in Potlatch or JOSM. Then rescaling and shifting
to the right place would be easy.

A link to the lake I would like to map:
http://www.openstreetmap.org/?lat=11.9201&lon=76.2459&zoom=12&layers=B000FTF

Would you know how to proceed to import this outline to JOSM ? And which
format to use ?

Thanks.
Guillaume
