       qmt_map2jnx - convert map to JNX

SYNOPSIS

       qmt_map2jnx  -q  <1..100>  -s  <411|422|444> -p <0..> -c "copyright notice" -m "BirdsEye" -n "Unknown" -x
       file1_scale,file2_scale,...,fileN_scale <file1> <file2> ... <fileN> <outputfile>

DESCRIPTION

       qmt_map2jnx is a helper utility for qmapshack(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 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:

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