Hi Carlos,

not sure if I understand what the problem is. The two screenshots show 
completely different tile boundaries, so they were not created from the same 
splitter output.

Betreff: [mkgmap-dev] Tiles pruned in DEM map

I build several types of map (OSM, OSM+contour lines, maps for trucks
and OSM+DEM) for the same area, using same input files. I split
country.o5m with splitter and then use the same template.args output by
splitter for all maps, just changing mapname for the different types of
map. Given that, all resulting mapsets should have the same tiles, but
tiles in DEM map are smaller than in the other types. They share part of
the boundaries (usually two of them) with other types, but other
boundaries are moved in, reducing displayed tile size. See attached
screenshots. However, file size is the same (discounting *.DEM) for each
tile in *.gmap subfolders.

Command is quite similar for OSM and OSM+DEM maps:

Both OSM and OSM+DEM maps can be downloaded from
https://alternativaslibres.org/en/downloads.php#Oceania

Any idea why this happens?
