[R-sig-Geo] Distance from coast

[Tomislav Hengl]

Sandeep,

You probably want to use:

*I had some problems automatic the processing with R+SAGA (will try to
update the maps/scripts soon), but this is probably what you are looking
for.

The geotifs are at:

http://spatial-analyst.net/worldmaps/

*we are in process of migrating to www.worldgrids.org which will include
both data and the geo-services.

cheers,

T. Hengl
