[mkgmap-dev] Tiles pruned in DEM map

Mon Dec 21 21:09:38 GMT 2020

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
