[mkgmap-dev] Hardcoded naming scheme for DEM tiles

Sat Oct 9 08:36:15 BST 2021

Hi,

I am trying to use the DEM/hillshading option. You can specify a path to 
the DEM tiles, but it seems that there is a hardcoded assumption about 
the naming format of the .hgt files.

I want to use an existing set of .hgt files used by another application 
which has a slightly different naming convention - in this case just a 
prefix. Of course it would be possible to copy all files to a new name, 
but it seems rather wasteful to copy such a large amount of data just 
because of naming issues.

So it would be very helpful to be able to not only specify a path but 
also a naming pattern to use, e.g. something like

--dem=p:/dem/prefix_N{$lat.2}E{$lon.3}.hgt

I would be willing to contribute the feature myself, but I am 
encountering difficulties - see separate mail.

bye,

         Nop
