+Spatial Module
+
+Creates the geometry layer based on RPCs (UTM->sensor and sensor-UTM).
+Checks and improves EnMAP co-registration and the keystone errors (user option?).
+Creates the image subsets (20 pixel shift - no mossaicing!!!).
+
+Input
+
+    L1B data
+    DEM or mean altitude
+    global or local shifts?
+    cloud masks for EnMAP
+
+Output
+
+    L1B data (coarse co-registered)
+    Geometry layer (sensor geometry => UTM)
+    Geometry layer (UTM => sensor geometry)
