Optical and radar data fusion for DEM generation
DEM generation SAR Interferometry Phase Unwrapping SPOT Stereoscopy Data Fusion
2016/5/20
This paper presents a DEM generation procedure based on optical (SPOT stereo) and radar (InSAR, interferometric SAR) data. The first part of the paper is focused on InSAR. The second one is concerned ...
LIDAR Data Reduction for Efficient and High Quality DEM Generation
LiDAR Laser Scanning DEM Interpolation Catchment Data Reduction
2015/12/8
Airborne Light Detection and Ranging (LiDAR) - also referred to as Airborne Laser Scanning (ALS), provides means for high density and high accuracy topographic data acquisition. LiDAR data have become...
comparison of dem generation and combination methods using high resolution optical stereo imagery and interferometric sar data
DEM/DTM High resolution Combination Fusion Accuracy Multisensor Optical SAR
2015/9/1
Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g. SPOT5, IKONOS) and...
