Prediction of Forest Stand Attributes Using TerraSAR-X Stereo Imagery
Consistent, detailed and up-to-date forest resource information is required for allocation of forestry activities and national and international reporting obligations. We evaluated the forest stand attribute prediction accuracy when radargrammetry was used to derive height information from TerraSAR-X stereo imagery. Radargrammetric elevations were normalized to heights above ground using an air...
متن کاملMapping forest types with TerraSAR-X imagery
Forest mapping and monitoring surveys are often based on costly and time-consuming field work. Satellite remote sensing data can facilitate these procedures over large forest areas [1]. Therefore, the Forest Research Institute of Baden Württemberg and the Department of Remote Sensing and Landscape Information Systems of the University of Freiburg aim on developing methods to support and to impr...
متن کاملPrediction of Plot - Level Forest Variables Using TerraSAR - X Stereo SAR Data
12 Promising results have been obtained in recent years in the use of high-resolution X-band stereo SAR 13 satellite images (with the spatial resolution being in order of meters) in the extraction of elevation 14 data. In the case of forested areas, the extracted elevation values appear to be somewhere between 15 the ground surface and the top of the canopy, depending on the forest characterist...
متن کاملDetection and Characterization of Hedgerows Using TerraSAR-X Imagery
Whilst most hedgerow functions depend upon hedgerow structure and hedgerow network patterns, in many ecological studies information on the fragmentation of hedgerows network and canopy structure is often retrieved in the field in small areas using accurate ground surveys and estimated over landscapes in a semi-quantitative manner. This paper explores the use of radar SAR imagery to (i) detect h...
متن کاملScreening of Earthen Levees using TerraSAR-X Radar Imagery
This paper presents early results of applying the TerraSAR-X multi-polarized data to the task of identifying problems on earthen levees. This application could save levee managers much time and expense in monitoring levees by prioritizing them according to urgency for closer inspection and analysis. One particular sign of potential impending levee failure is the appearance of a slough slide. Ea...
