Using OSM map on garmin / summit names/height

The best place to ask is on the mkgmap mailing list.

okay thanks, I was not sure if I should ask for this problem here or on mkgmap

I'm using the osm data extracts from geofabrik.de and convert them to garmin image with splitter/mkgmap.

What actual commands are you using? What mkgmap map style are you using?

https://www.mkgmap.org.uk/websvn/filedetails.php?repname=mkgmap&path=%2Ftrunk%2Fresources%2Fstyles%2Fdefault%2Fpoints&peg=4896 contains this line:

natural=peak {name '${name|def:}${ele|height:m=>ft|def:}'} [0x6616 resolution 24]

and I'd expect that that will appear as something like "Peak name, xyz M". It certainly does on my Garmin GPSMap 64s using a rule similar to that.

Yes, that was the problem. Now it would be interesting which data the Garmin uses to calculate the altimeter if I want it to route me to the summit?!

I'm not sure what you mean by "calculate the altimeter" here.

A mkgmap-generated map has two sets of attributes:

• what you see on the screen
• (optionally) routing information for various modes of transport.

I suspect that the altitude of a feature doesn't have any bearing on the the routing suggested, but people on the previously-mentioned mkgmap list would be likely to know.
