To make geodata work:
* unpack your geodata files into "/data/geodata" folder (or any other folder)
* open "/config/GeoEngine.ini" with your favorite text editor and then edit following configs:
- GeoDataPath = set path to your geodata, if elsewhere than "./data/geodata/"
- GeoDataType = set the geodata format, which you are using.
