Several aerial missions equipped with airborne laser scanner (TopoSys Falcon II, Riegl LMS-Q560) and airborne digital camera (TopoSys line scanner, DLR HRSC-A) were flown in two forest districts in Northrhine-Westfalia in the years 2004-2007. The study sites Glindfeld (76km^2) and Schmallenberg (280km^2 ) are located in the low mountain range Sauerland in Northrhine-Westfalia, Germany. Main economic important tree species are spruce (Pices abies) and beech (Fagus sylvatica).
