.SH "DESCRIPTION"
\fBqmt_map2jnx\fR is a helper utility for qmapshack(1) to convert a map
to JNX format.
.PP
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.
.PP
To rectify a geotiff map, you can use the gdalwarp command, e.g.
.IP
gdalwarp \-t_srs "EPSG:4326" <inputfile> <outputfile>
.PP
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:
.IP
\-x 45356,,,75; \-x ,,,,75
.PP
