I have successfully built contour map for Spain using srtm2osm -> splitter -> mkgmap. I combine srtm img's and regular map img's with mkgmap. Up to here everything goes fine. The problem now is that major and medium contour lines are shown at any zoom level in MapSource and gps, not taking into account resolution established in style (see below). It makes rendering really slow when you zoom out and all the map is covered by contour lines. Minor contour lines do appear at the right zoom level (1.5 km in MapSource). The problem is in the contour map, because it's the same if I only install it (without regular map). Contour lines style used: |contour=elevation & contour_ext=elevation_minor { name '${ele|conv:m=>ft}'; } [0x20 resolution 23] contour=elevation & contour_ext=elevation_medium { name '${ele|conv:m=>ft}'; } [0x21 resolution 22] contour=elevation & contour_ext=elevation_major { name '${ele|conv:m=>ft}'; } [0x22 resolution 20]| Commands used: *srtm: mono Srtm2Osm.exe -bounds1 35.99 -9.501 43.79 4.33 -step 10 -cat 100 20 -large -corrxy 0.0005 0.0005 -o srtm_peninsula.osm

It was "levels = 0:23, 1:22, 2:20"; changing it to "levels = 0:23, 1:22, 2:20, 3:18" fixed the problem. In the wiki [1] its stated that the lowest level needs to have at least one object in it, but it seems to be right the opposite, as I needed to add an extra 3:18 level which has no object in it to get it work. I know this page of the wiki is quite outdated (there was no mention to styles in it), so if you can give some information about this issue I will update it accordingly. Now that contour lines are correctly drawn a new problem arises. If I combine contour img's with osm img's either with mkgmap or gmaptool all map becomes flooded. If I combine them with MapSource land is ok, but routing is broken. So, there must be still something I'm doing wrong. [1] http://wiki.openstreetmap.org/wiki/Mkgmap/help/custom#Level
