摘要：In this paper forest inventory methods which are based on satellite remote sensing and laser-scanner data will be intro- duced. It will be demonstrated in how far conventional terrestrial inventories at a scale of 1 : 10.000 to 1 : 25.000 can benefit from the synergetic use of both sensor types. The forest inventory parameters to be investigated are: tree height, timber volume, tree species, tree age, stand border, and basal area. The presented results are mainly derived from the following projects ￠ HIGHSCAN (Assessing forest stand attributes by integrated used of high-resolution satellite imagery and laser- scanner), EU - DG XII, CEO, co-ordinated by the Helsinki University of Technology and financed by the EU, ￠ ALPMON (Inventory of alpine-relevant parameters for an alpine monitoring system using remote sensing data and GIS), EU - DG XII, CEO, co-ordinated by Joanneum Research Graz ￠ SEMEFOR, Satellite based environmental monitoring of European forests, EU-DG XII, Pilot Projects, co-ordinated by Swedish Environmental Institute, Stockholm The projects are conducted in close co-operation with forest private and governmental management administrations. In this paper the results derived from different test sites will be presented
