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

From Joao Almeida joaoha at gmail.com on Tue Sep 15 02:42:58 BST 2020

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
