QMT_MAP2JNX(1) QMT_MAP2JNX(1)

qmt_map2jnx - convert map to JNX
 

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>
 

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:
English: http://whiter.brinkster.net/en/JNX.shtml
Russian: http://whiter.brinkster.net/JNX.shtml
Most common values for different map scales:

JNX scale Map scale
------------- ---------
78125-31250 1:1 000 000
20834-7813 1:500 000
