Hi Steve, only class GeoTiffDEM is optional, the active code is able to read *.hgt files and can produce ways with elevation data. I stumbled over it because it appears in MapperBasedMapDataSource.addBackground() which I plan to move to MapDetails so that we don't have to override it in many sources. I like the idea that mkgmap adds SRTM data "on the fly" instead of first creating huge OSM files, pass them through splitter and so on. No idea how much work would be needed to make the code work and how many poblems that would cause, esp. if we also try to download SRTM files automatically.

mkgmap contains sources to generate contour lines from SRTM data, but it seems to be very incomplete. The last significant changes in the source was in 2010, and I never heard that anybody uses options like --x-contours since I started to contribute to mkgmap.
All classes in packages named "optional" are not included in the download distribution. So it has never been available except if you compile the source yourself and include it. ..Steve _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
