[mkgmap-dev] Garmin Contour Lines

Hi Markus,

the Garmin img format doesn't allow such a resolution. It uses only 24 bits 
to store the lat / lon values, that means 40000km / 2^24 which gives ~ 2.4m on the equator.
Think of a "bed of nails" with one nail every 2.4 meter and try to draw lines 
by connecting these nails.

Betreff: [mkgmap-dev] Garmin Contour Lines


Is it in general possible to convert high detailed Height- Lines to a garmin Map ?

 High Detailed means Lines with 1m distance in height.

I tried but my Lines look useless because they look cross-connected

So how to generate such contour lines ?
