GIS DEM/DTM Error Correlation Impact Analysis Modelling Reference Data Glaciology
2015/9/28
For realistic modelling of digital elevation model (DEM) uncertainty, information on the amount and spatial configuration is needed.However, common DEM products are often distributed with global error...
Improvement of Forest Height Retrieval By Integration of Dual-Baseline PolInSAR Data And External DEM Data
Forest height retrieval Polarimetric synthetic aperture radar interferometry (PolInSAR) Sloped-Random volume over ground(S- RVoG) Dual-baseline
2015/7/27
In recent years, a lot of studies have shown that polarimetric synthetic aperture radar interferometry (PolInSAR) is a powerful technique for forest height mapping and monitoring. However, few researc...
