[mkgmap-dev] DEM file and the block-size option

Sat Jan 13 15:10:18 GMT 2018

Hi,

I got once overview bigger than 32M and I had to decrease DEM 
resolution. 64MB seems quite big for an overview.

Anyway, I have provided this patch, because I have finally found the 
reason for big MDR sizes. I hope at least this one correction can be 
moved to trunk.
