Hi, I've noticed some inconsistencies in the rendering of heights of peaks. In the default style file, the altitude is converted from meters to feet because Garmin likes that. natural=peak {name '${name|def:}${ele|height:m=>ft|def:}' } [0x6616 resolution 24] Here are some examples where it goes wrong: Kahler Asten, near Winterberg, Germany http://www.openstreetmap.org/browse/node/83318818 GPS shows: 256m Mapsource: no height info osm tags: * ele: 840,8 * name: Kahler Asten * natural: peak Wetztstein, near Winterberg, Germany http://www.openstreetmap.org/browse/node/664200355 Gps shows 235m Mapsource: no info osm tags: * ele: 771 m * name: Wetzstein * natural: peak Example where it is rendered correctly: Bremberg near Winterberg, Germany http://www.openstreetmap.org/browse/node/316037203 Gps shows 809m Mapsource: 809m osm tags: * ele: 809 * name: Bremberg * natural: peak So only if the altitude is given in numbers (without decimal fractions or m) it is rendered correctly. I'm sure this can be improved in the style file by some kind of logical expression but how?
