[Qlandkartegt-users] map2jnx documentation?
Since QlandkarteGT fails to export geotif to jnx for me (see previous mail) I made the steps QlandkarteGT said it takes by hand: # extract the area from the files... /usr/bin/gdal_translate -co BIGTIFF=yes -co tiled=yes -co compress=DEFLATE -srcwin 0 0 37752 83348 source.tif qlgt_1.tif # reduce colorbands to 3 (RGB)... /usr/bin/gdal_translate -co BIGTIFF=yes -b 1 -b 2 -b 3 -co tiled=yes -co compress=jpeg -co jpeg_quality=100 qlgt_1.tif qlgt_2.tif # reproject files... /usr/bin/gdalwarp -t_srs EPSG:4326 -ts 992 991 -r cubic -co tiled=yes -co compress=jpeg -co jpeg_quality=100 qlgt_2.tif qlgt_3.tif up to here everything is fine, but when I run: # creating Garmin JNX map... /usr/bin/map2jnx -q 75 -s 411 -p 0 -m foo -n bar -c -z 50 qlgt_3.tif destination.jnx I get the error: ** map2jnx, Version 1.7.0 ** ERROR 4: `50' does not exist in the file system, and is not recognised as a supported dataset name. Obviously this message refers to -z 50 - but I copied the command as it is from the QlandkarteGT output. Since map2jnx has neither a manpage nor a --help or -h output I have to ask here how to get it working.

Re: [Qlandkartegt-users] Export to jnx fails

Thus I never prepared the commands for that. Anyway, GeoTiff might be able to support more than 4GB, JNX won't for sure. The format uses 32bit pointers into the file. Since the GDAL conversions are done in high quality and jnx is quite compressed the source of 8GB results in a lot smaller jnx file - in this case 470 MB. There is a help. Simply enter the command map2jnx without any paramter. Your commandline fails because you use the -c paramter without a value. In this case it's probably and QLGT's output represents that fact badly. With -c it works Thanks for the quick reply!
