Hi all,<br><br>I've just checked in Lakewalker, a tool that can be used to<br>automatically generate coastline data from NASA's Landsat imagery. I've<br>used it to trace a lot of the lakes and islands in my area; an example
<br>can be seen at<br><a href="http://www.informationfreeway.org/?lat=53&lon=-100.5&zoom=12&layers=0B00F000">http://www.informationfreeway.org/?lat=53&lon=-100.5&zoom=12&layers=0B00F000</a><br><br>
<br>The resulting data is significantly higher resolution than the PGS<br>import, and can be used in areas where there is no PGS data.<br><br>Lakewalker resides in<br><a href="http://svn.openstreetmap.org/applications/utils/import/lakewalker">
svn.openstreetmap.org/applications/utils/import/lakewalker</a>, and requires<br>Python and the Python Imaging Library. Minimal documentation is<br>available in the README and with the --help option.<br><br>If you have questions or suggestions, feel free to email me directly or
<br>look for me on #osm.<br><br>- Darryl (DShpak)<br><br><br>_______________________________________________<br>talk mailing list<br><a href="mailto:talk@openstreetmap.org">talk@openstreetmap.org</a><br><a href="http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk">
