       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
               -------------          ---------
               78125-31250            1:1 000 000
