.SH DESCRIPTION
\fBmap2jnx\fR is a helper utility for
\fBqlandkartegt\fR(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
\fBgdalwarp\fR(1)
command, e.g.

.nf
\*(T<
\fBgdalwarp\fR \fB\-t_srs\fR \fI"EPSG:4326"\fR \fIinputfile\fR \fIoutputfile\fR
      \*(T>
.fi
.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:

.nf
\*(T<
  \fB\-x\fR 45356,,,75; \fB\-x\fR ,,,,75
      \*(T>
.fi
.PP
