Hi, Is there a document that describes how to include strm contour lines in my Garmin maps? What is the best practice? Normally I generate maps for The Netherlands, so contour lines are not that important to me. But this summer we will be going to Austria so I want to include them. I can use srtm2osm to download the data in .osm-format, but is there a document describing how I can add them to my Garmin map? Do I need to create a new family-id? There are several threads to this list in the archives in Q3 of 2009 about native srtm support. But is this feature described a bit more in detail? I can't find anything about this in the help. One of the threads starts at: http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2009q3/002581.html Thanks in advance, Frank
