There must be something wrong with the Ozi mapfile is not correct. Does it work
with Ozi?

Point01,xy,    0,    0,in, deg,    ,        ,,    ,        ,, grid,
55,219999.09067205,5570000.7412442,S
Point02,xy, 1000, 1000,in, deg,    ,        ,,    ,        ,, grid,
55,223259.16350298,5566740.6684133,S

Control points are clearly in degrees but in that place or the Ozi mapfile there
should be projected grid coordinates.

This page describes the Ozi mapfile structure
http://code.google.com/p/androzic/wiki/MapFile. You can also install OziExplorer
Trial version, rename the .map file and re-calibrate the jpeg image with Ozi and
see how it writes the map file.
