Hi all,

I've just checked in Lakewalker, a tool that can be used to 
automatically generate coastline data from NASA's Landsat imagery. I've 
used it to trace a lot of the lakes and islands in my area; an example 
can be seen at 

The resulting data is significantly higher resolution than the PGS 
import, and can be used in areas where there is no PGS data.

Lakewalker resides in 
svn.openstreetmap.org/applications/utils/import/lakewalker, and requires 
Python and the Python Imaging Library. Minimal documentation is 
available in the README and with the --help option.

If you have questions or suggestions, feel free to email me directly or 
look for me on #osm.
