I'm sorry, probably I didn't explain well enough.
Overview is always correct, the problem affects only tiles. As you saw
in the screenshots of my first mail, they are different in size, but
they are generated from the same input files, so they should have the
same size. If you zoom in to an area that should be included in a tile,
only overview map is shown, no detailed map. Even more, when you zoom
in, at the given point where detailed map appears, tile boundary jumps
to the correct size, but nothing but overview is displayed outside the
"pruned" tile.
You can download correct and wrong files from the links below and play
with them to get a better idea of the problem. They correspond to first
tile of Australia as shown in my screenshots.

Although removing --overview-dem-dist solved the issue in my first test
(see command below, correct output), after a lot of tests removing
options one by one from the original command, finally it seems the
problem is caused by option --order-by-decreasing-area (or the
combination of both).

Hi Carlos,
It seems I still don't understand what the problem is or how to reproduce it.
I tried this command and the overview map looks OK:
java -Xmx4G -jar d:\mkgmap\dist\mkgmap.jar --dem=f:\srtm3
--overview-dem-dist=128000 --show-profiles=1 --gmapi
f:\dwnload\temp\51145001.o5m
If it is related to the DEM data I probably cannot help much. You may try a
slightly different value for the --overview-dem-dist option or a modified
polygon
given with the --dem-poly option.

Betreff: Re: [mkgmap-dev] Tiles pruned in DEM map
The problem seems to be caused by overview DEM. If I remove
--overview-dem-dist option tile is complete in MapSource. The issue can
be reproduced with this tile
<https://alternativaslibres.org/tmp/51145001.o5m> and HGT from
vierfinderpanoramas3

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?
