valgeomap.pl  is used to map  the Lambert Conformal Conic Coordination System, which is used
in the GIS atlas, to World Geodetic System of 1984 (WGS84) which is used in Google earth.
The converting formulas could be found in the pdf files in this directory. You could find more
conversion formulas in these files. 

Here is an example.

You can you the gdalinfo command to retrieve the geography coordination information. you coud use
these information as the parameters to conversion.
