Overview
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.
FC
gdalwarp -t_srs "EPSG:4326" inputfile outputfile
F[0]
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:
FC
-x 45356,,,75; -x ,,,,75
F[0]

Most common values for different map scales:
FC JNX scale Map scale ------------- --------- 78125-31250 1:1 000 000 20834-7813 1:500 000 7813-3125 1:200 000 3125-2084 1:100 000 2084-782 1:50 000 782-32 1:25 000 32-21 1:10 000 21-14 1:5000, 1:2000 F[0].fi
