A METHOD OF GENERATING DEM FROM DSM BASED ON AIRBORNE INSAR DATA
InSAR DSM Adaptive Threshold Segmentation DEM, Filtering
2018/5/15
Traditional methods of terrestrial survey to acquire DEM cannot meet the requirement of acquiring large quantities of data in real time, but the DSM can be quickly obtained by using the dual antenna s...
Towards optimal relief representation from Mars imagery by combination of DEM and shape-from-shading
Mars imagery combination DEM shape-from-shading
2016/5/20
Described are experimental results of a first approach towards optimal shaded relief representation of the surface of Mars derived from Viking Orbiter digital imagery. The complex problem addresses ho...
Effect of DEM Resolution on the Simulation of Astronomical Radiation
DEM Astronomic Radiation Resolution Sensitive Analysis
2015/12/2
The development of digital terrain analysis based on DEM is helpful for the simulation of astronomic radiation in rugged area. However the effect of DEM scale causes great uncertainty to the simulatio...
Putting The Pieces Together: Composing a Nationwide Dem-cover of Belgium
Multisource DEM Combination
2015/7/7
Ideally a country (region, city, etc.) is covered with homogeneous data sets. Unfortunately, this ideal situation does not often present
itself. Frequently, we have a number of different existing dat...
Aspects of Raster DEM Data Derived from Laser Measurements
DSM DTM DEM echo filtering Falcon intensity laserscanning laserscanner data raster data TopoSys
2015/5/26
The „normal“ product of a TopoSys DEM is a raster based DSM / DTM. A TopoSys DSM / DTM is not a standard product. It is
processed for the application of the customer. Because of the high data r...
IMAGE CLASSIFICATION FROM LANDSAT TM, AIRBORNE MAGNETICS AND DEM DATA FOR MAPPING PALEOPROTEROZOIC BEDROCK UNITS, BAFFIN ISLAND, NUNAVUT, CANADA
Bedrock Mapping Geology Classification Remote Sensing Nunavut
2015/2/4
A novel approach in image classification to bedrock mapping is applied to a 1:100 000 scale map area
of the Meta Incognita Peninsula Baffin Island, Nunavut, Canada to support mapping of the

SAR IMAGE GEOCODING USING A STEREO-SAR DEM AND AUTOMATICALLY GENERATED GCPs
Automation Control strategies DEM Geo-referencing RADARSAT Simulation Spatial data Stereo SAR
2014/12/29
SAR image geocoding needs an accurate DEM, but such a DEM can be difficult to obtain. This paper shows that the needs of geocoding can be satisfied using the DEM generated by employing a rigorous geom...
