The Application of Remote Sensing Techniques for Surveys on Forest Damage.

Abstract

For surveys of forest damage of fir, pine, beech and oak stands ten test areas were selected, with a variety of influencing environmental parameters like topography, stand of trees, species. Eight institutions are cooperating, using aerial CIR photos and multispectral scanner data from airborne and satellite platforms. Different image correction and processing methods are applied, including spectral sinature analysis and additional spectroradiometer measurements on the ground. Results obtained indicate that by the use of supervised classification, based on spectral differencesof healthy and damaged classes, good and reliable results can be obtained for larger homogeneous stands using airborne data.
