-Currently the national and the extended european grids are supported.
-Tested input products are PG, FZ, SF, RW, RX and EX. Those can be considered working with
-sufficient accuracy.
+Besides local scans, the following grids are currently supported:
+- National Grid (900km x 900km)
+- National Picture Grid (920km x 920km)
+- Extended National Grid (900km x 1100km)
+- Middle-European Grid (1400km x 1500km)
