Because of his forest density the “Pfälzerwald” is the largest woodland of the federal republic of Germany. Within his classification as biosphere reserve it is departed in 3 zones of different protection and development aims. The so called core zone has the highest protection status. In the core zone the natural processes should not be influenced by humans.
The main methodology was based on the integration of actual remote sensing methods like the GIS based analysis of digital elevation models by ALS (Aiborne Laserscanning) or photogrammetic creation. Additionally digital air images with an integrated infrared channel were used. Tree height, canopy cover, gaps and differentiation between deciduous and coniferous trees were used to answer forest ecological and forestry questions.
In addition to this dynamic information more topographic information could be derived on the basis of a high-resolution digital terrain model. This includes for example the topographic soil moisture, the topographic sun exposure, the slope gradient, the exposition or heat islands.
