AN INTERFEROMETRIC PROCESSING METHOD TO MAINTAIN BOTH ACCURACY AND RESOLUTION OF DEM USING GAOFEN-3 SAR DATA
Gaofen-3, TanDEM-X, DEM, multi-look
2018/5/14
Gaofen-3 (GF-3) is the only in-orbit SAR satellite of China civilian fields. It is designed especially for ocean observation but not for interferometric applications. However, during the past one and ...
AN IMPROVED DEM CONSTRUCTION METHOD FOR MUDFLATS BASED ON BJ-1 SMALL SATELLITE IMAGES: A CASE STUDY ON BOHAI BAY
Mudflats BJ-1 image Waterline detection method Tidal grid model DEM
2018/5/15
The topographic measurement of muddy tidal flat is restricted by the difficulty of access to the complex, wide-range and dynamic tidal conditions. Then the waterline detection method (WDM) has the pot...
PRELIMINARY GAOFEN-3 INSAR DEM ACCURACY ANALYSIS
GF-3 satellite, error analysis, calibration, digital elevation model, precision validation
2018/5/11
GF-3 satellite, the first C band and full-polarization SAR satellite of China with spatial resolution of 1 m, was successfully launched in August 2016. We analyze the error sources of GF-3 satel...
COMBINING HIGH RESOLUTION SATELLITE IMAGERY AND AIRBORNE LASER SCANNING DATA FOR GENERATING BARELAND DEM IN URBAN AREAS
Airborne Laser Scanning IKONOS
2015/3/9
This paper proposes a framework for generating bare-land Digital Elevation Model (DEM) in urban areas by combining highresolution satellite imagery and Airborne Laser Scanning (ALS) data. Airborne las...
