[mkgmap-dev] Commit: r1576: There seems to be a way to show elevation profiles

Sat Feb 20 10:06:23 GMT 2010

Hi,
I use the standard Garmin types for contour lines, 0x20, 0x21 and 0x22

I created the contour lines with Srtm2Osm, split srtm.osm data with the same
tile area bounds as my map. Now I have two img's of the same area,
one with osm data, one with contour lines.
E.g. 10010001.img and 10010101.img

The contour tile is transparent so I can see the contours on top of the map
in Mapsource. 

Is it possible to merge those two layers into one tile and still keep the routing?
How can I merge the two 10010001.osm with 10010101.osm or 10010001.img with 10010101.img?

Will it be possible to show the elevation profile with this approach?

Cheers, 
Minko

This works fine for me (in 6.15.11).
Did you use the standard Garmin types for elevation(0x20-0x21)?
