The tool creates the blend- and watermask, based on shapefiles and resamples.
Furthermore, it is able to create 5 seasons (winter, hardwinter (snow), spring, summer and fall) and can change enhance the colors of the Ortho4XP imagery.
To avoid loading problems when creating huge areas, this tool merges around 50-100 single images into one bgl.
