[mkgmap-dev] DEM file Number too big for binary encoding with 14 bits

Wed Sep 23 13:47:53 BST 2020

Thank you Gerd,

So I narrowed it down a bit more. I'm getting a similar behavior when 
trying to build Russia with DEM. But because it is quite a big file I'm 
doing it with ANZ.

Here are my findings.
It seems to be related to DEM and only affecting New Zealand. If I build 
Australia using the same settings/options/style I get a working map.

If I build New Zealand without DEM and only contours I get a working 
map. Note the contours are created from the same HGT files, so I would 
assume the HGT files are correct.
If I build New Zealand without DEM or contours I also get a working map, 
so I would say that would eliminate a TYP or Style issue.

Also I mentioned I can create a DEM map for Australia without a problem 
with the same DEM options so I would say the DEM settings would not be a 
problem but I don't know for sure.

Here are the settings:

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

Build command line:
java -Xmx8192m -ea -jar C:\Garmin\MKGMAP~2\mkgmap.jar --mapname=37406557

PAUSE

When I build the New Zealand map I only get a map at zoom level 30km or 
below with Basecamp set to map detail High.
The output from this build command line is attached.

screenshot NZ1 -- no map at all except for some islands New zealand 
should be where the tracks are.
screenshot NZ2 -- we have some parts of the map but the east side of New 
Zealand is cut.

screenshot NZ3 -- a lower zoom level the east side of New Zealand appears.

Thanks for the help.
