MODEL ACCURACY COMPARISON FOR HIGH RESOLUTION INSAR COHERENCE STATISTICS OVER URBAN AREAS
Interferometric Synthetic Aperture Radar (InSAR) Coherence Statistics Model Accuracy Urban Areas
2016/11/24
The interferometric coherence map derived from the cross-correlation of two complex registered synthetic aperture radar (SAR) images is the reflection of imaged targets. In many applications, it can a...
Analysis of software requirements to represent urban areas with DEMs and 3D visualization of buildings and structures
DEM (Digital Elevation Models) Visualization of 3D DSM (Digital Surface Modeling)
2016/5/20
In order to have an integrated view of an urban area, it is necessary to show the terrain and the structures on it. There are many established computer programs that can do efficiently either task ind...
INTERPRETATION OF HIGH RESOLUTION SAR DATA USING EXISTING GIS DATA IN URBAN AREAS
SAR Registration Simulation Georeferencing GIS Change Detection Urban Building
2015/8/7
Within the paper the automatic matching of existing GIS data to airborne SAR scenes for georeferencing is discussed. For this purpose simulated SAR images are generated based on the available GIS obje...
