[mkgmap-dev] [PATCH] Creating contour lines from DEM data

Fri Jul 3 21:34:41 BST 2009

Hi Christian,

congratulations, that is very good work.

As there are some people on this list who will publish their created  
maps I'll have to add a caveat though: You should make sure that the  
data source you use for the generation of the contour lines is  
compatible with the OSM license. See http://wiki.openstreetmap.org/wiki/Legal_FAQ 
  and http://wiki.openstreetmap.org/wiki/Common_licence_interpretations.

The reason why I bring that up is that for example the improved SRTM  
data by CIAT-CSI is in my opinion *not* compatible with the OSM license!

Regards
Thilo
