       map2jnx - convert map to JNX

SYNOPSIS

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

DESCRIPTION

       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 Longi‐
       tude/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  autode‐
       tect.  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:

         JNX scale              Map scale
         -------------          ---------
