# map2jnx(1)

convert map to JNX

## NAME

map2jnx - convert map to JNX

## SYNOPSIS

**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

**map2jnx** is a helper utility for [**qlandkartegt**(1)](/qlandkartegt/1.md) 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**(1)](/gdalwarp/1.md) command, e.g.

```
FC
gdalwarp -t_srs "EPSG:4326" inputfile outputfile
      F[0]
```

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:

```
FC
  -x 45356,,,75; -x ,,,,75
      F[0]
```

Most common values for different map scales:

```
FC
  JNX scale              Map scale
  -------------          ---------
  78125-31250            1:1 000 000
  20834-7813             1:500 000
  7813-3125              1:200 000
  3125-2084              1:100 000
  2084-782               1:50 000
  782-32                 1:25 000
  32-21                  1:10 000
