Description: Satellite remote sensing is being used operationally by Swedish authorities in applications involving, for example, change detection of clear felled areas, use of k-Nearest Neighbour estimates of forest parameters, and post-stratification (in combination with National Forest Inventory plots). For forest management planning of estates, aerial photointerpretation in combination with stand-wise field surveys is used. Automated analysis of digital aerial photos is a promising technique for tree species classification; laser scanning is being applied to assess tree height, stem volume, and tree size distribution; and low-frequency radar is being used for stem volume estimation. Obtaining timely photos of single stands from small unmanned aircraft is also an increasingly realistic option.
