Overview
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
