1:50000 Scale Topographic Mapping in West China Using SPOT 5 Data
Mapping SPOT Geometric Modelling DEM Accuracy
2015/12/18
On the one hand, the successful launch of the SPOT 5 satellite in 2002 can be seen as a milestone for DEM extraction and mapping, because its payload includes HRS, a stereoscopic imaging instrument de...
Application of SPOT-5 Imagery in Surveying and Mapping of West Regions in China
Satellite Remote Sensing Digital Maps Digital Photogrammetry Absolute Orientation
2015/12/17
During the past 50 years, there are no topographic maps at scaled of 1:50,000 in the West Regions of China. Beside the extremely adverse environmental condition of the regions, the poor surveying and ...

Oil spill surveillance is of great environmental and economical interest, directly contributing to improve environmental protection. Monitoring of oil spills using synthetic aperture radar (SAR) has r...
Multi-Image Matching for DTM Generation from SPOT-5 HRS/HRG and IRS-P5 Imagery - For the Project of West China Topographic Mapping at 1:50,000 Scale
Geometrical Constrained Cross-Correlation
2015/11/23
High-resolution satellite images (HRSI) at sub-5m footprint such as IKONOS, IRS-P5 (CartoSat-1) and SPOT-5 HRG/HRS images are becoming increasingly available to the earth observation community and the...
A GENERIC PUSHBROOM SENSOR MODEL FOR HIGH-RESOLUTION SATELLITE IMAGERY APPLIED TO SPOT 5,QUICKBIRD AND ALOS DATA SETS
Pushbroom sensor SPOT 5 QuickBird ALOS PRISM
2015/9/17
A new generic pushbroom sensor model for high-resolution satellite images is presented. The sensor orbit and attitudes are modelled by splines. In order to determine the parameters of the orbit and at...
Digital Elevation Models (DEMs) represent the terrain elevation in discrete form in three-dimensional space. This is the simplest form of 3D-terrain representation and the most common. The accuracy an...
PRODUCTION OF VEGETATION INFORMATION TO 3D CITY MODELS FROM SPOT SATELLITE IMAGES
Forest mapping satellite imagery 3D city model atmospheric calibration 3D visualisation
2015/9/17
The paper presents a methodology to produce forest parameters and tree instances to large area 3D maps or city models from satellite images. The process flow includes the calibration of the satellite ...
AUTOMATIC PRODUCTION OF A EUROPEAN ORTHOIMAGE COVERAGE WITHIN THE GMES LAND FAST TRACK SERVICE USING SPOT 4/5 AND IRS-P6 LISS III DATA
