5.000000000000 (size of pixel in x direction)
0.000000000000 (rotation term for row)
0.000000000000 (rotation term for column)
-5.000000000000 (size of pixel in y direction)
492169.690845528910 (x coordinate of upper left of upper left pixel)
5426523.318065105000 (y coordinate of upper left of upper left pixel)
Projection is direct polar relative to lat/lon 0;0 but unit is meters.
This gives sensible results if the map is used in e.g. qgis.
circumference of the Earth at the equator = 40 075.017 km
circumference of the Earth through the poles = 40 007.863 km
map_* world files use the following world file format:
5000.000000000 (scale)
0.000000000000 (ignored)
0.000000000000 (ignored)
-5000.00000000 (-scale)
49.690845528910 (longitude)
26.318065105000 (latitude)
latitude, longitude and scale taken from map_koord.txt
The above world file does not give sensible results in other GDAL applications
it uses a special hard coded case.
