[mkgmap-dev] BuildDEMFile: system out of memory

Sat Dec 9 20:31:08 GMT 2017

Hi Nick,

My max-nodes are much higher than yours, I use --max-nodes=1800000

Hi Minko

Very strange, when I add DEM to your gmapi files the DEM doesn't show at all, even though the files exist.

I noticed that your maxnodes are quite low, ie mine are set at 160,000 and with this setting  builddemfile creates the desired dem effect using the canary islands pbf

Using your files I noticed  builddemfile creating lots of dem files,containing mere  dummyvalues.

I tend to avoid  such files.

Just a thought : perhaps experiment with higher maxnodes?

Hi Frank,

I was running your tool on my Atlantic map and got a system out of memory error. The script did continue to build the dem data but in my map a few islands in the center of the map were missing DEM data (see the red area in the attachment, Sao Miguel on the Azores and La Palma and El Hierro on the Canary Islands). Any idea how to solve this issue?

The map OFM_Atlantic(13-10-2017_gmap you can download at

http://www.openfietsmap.nl/downloads/atlantic

DEM tiles I downloaded from http://www.javawa.nl/srtm/index.php?lang=en (viewfinder panoramas)

The command that I used is:

for /D %%i in (34351*.*) do (BuildDEMFile.exe -d %%i\%%i.DEM --hgtpath=%hgtpath% --tre=%%i\%%i.TRE --lastcolstd --usedummydata --dlon=0.00027761
)
