map2jnx is a helper utility for qlandkartegt to convert a map to JNX

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 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,

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

Calculated levels table can be found:

Most common values for different map scales:
