[mkgmap-dev] DEM There is not enough room in a single garmin map for all the input data

Tue Sep 15 09:05:00 BST 2020

Hi Joao,

you probably have a large tile that contains rather few OSM details but a lot of DEM data. Mongolia would be a typical candidate. With your change of the --dem-dist option you removed several DEM levels and thus drastically reduced the number of  bytes needed for that data.

Reporting I found a fix for this.
I stopped having the messages and being able to compile my maps after I
changed the following options:

Before:
--dem-dists=3312,3312,9942,13248,26512,44176
--overview-dem-dist=88368

After:

--overview-dem-dist=88888
--dem-dists=9942

I'm not sure why some tiles where throwing the error, because I was able
to compile other areas with the original settings.

Not sure if someone has an answer or wants to investigate.

Cheers
