ESTIMATION OF FOREST CURRENT STATE AND DYNAMICS USING GIS

摘要：

This paper addresses a GIS-aided method of forest vegetation dynamics mapping based on a combined analysis of multi-band optical satellite data, a digital elevation model (DEM), and ground data. An unsupervised classification procedure applied to remote sensing (RS) scenes and DEM-composite (elevation, slope and curvature) images is used to map forest vegetation dynamics and growth conditions in combination with spatial intersection and generalization approaches. Based on the methodology described, Landsat 7 ETM+ satellite imagery, SRTM 90m DEM, and field data were processed for the Lower Angara test site. The resulting map includes two polygonal vector layers: one is forest regeneration stages and the other is forest vegetation succession series in a range of site conditions.
