Hi Gerd,

if finalized, would „mkgmap –gmapi“ create the DEM-files in the „product1-folder. As far as I Tested it yet, it doesn´t“?

Betreff: [mkgmap-dev] DEM size in Garmin Basemap > 16MB

Hi,

I've just noticed that the DEM file in my Oregon basemap (gmapbmap.img) is ~ 31MB.
Up to now I thought that 16MB is either the limit for a single file in an img or for the whole img file.
Both seems to be wrong.

@Steve: The value is coded in BufferedImgFileWriter:
// The maximum allowed file size.
private long maxAllowedSize = 0xffffff;

Is that an mkgmap limit or do you think that Garmin uses a special trick for the base map?

Gerd
