map2jnx - convert map to JNX


map2jnx -q 1..100 -s 411|422|444 -p 0.. -c "copyright notice" -m "BirdsEye" -n "Unknown"

map2jnx is a helper utility for qlandkartegt(1) to convert a map to JNX format.

The projection of the input files must have the same latitude along a pixel row. Mecator
and Longitude/Latitude projections match this this property. Transversal Merkator or
Lambert projections do not.

To rectify a geotiff map, you can use the gdalwarp(1) command, e.g.

gdalwarp -t_srs "EPSG:4326" inputfile outputfile

Scale levels must be pass in same order as level files pointed. Empty and zero values
equal to autodetect. We can point only needed levels, like:

-x 45356,,,75; -x ,,,,75

Calculated levels table can be found:

Most common values for different map scales:
