Evaluation of Cartosat-1 Multi-Scale Digital Surface Modelling Over France
On 5 May 2005, the Indian Space Research Organization launched Cartosat-1, the eleventh satellite of its constellation, dedicated to the stereo viewing of the Earth's surface for terrain modeling and large-scale mapping, from the Satish Dhawan Space Centre (India). In early 2006, the Indian Space Research Organization started the Cartosat-1 Scientific Assessment Programme, jointly established w...
متن کاملRational Polynomial Modelling for Cartosat-1 Data
Cartosat-1, ISRO’s first satellite with along track stereo capability was launched in May 2005 providing high-resolution stereo imagery of earth’s surface for cartographic applications. Providing relevant ancillary information along with the data product is the general practice followed by satellite data providers. Rational Polynomial Camera (RPC) model is used to represent the imaging geometry...
متن کاملDigital Elevation Model Generation and Retrieval of Terrain Attributes using CARTOSAT-1 Stereo Data
Terrain analysis is a very important part of the study of surface processes. Although several techniques have been used historically to study terrain, the use of satellite imageries has become one of the optimum methods now. Presently there are lots of satellite imageries available for extraction of elevation features microwave optical etc. The stereo pair images have a great potentiality in th...
متن کاملOrthorectification and Digital Elevation Model (DEM) Generation Using Cartosat-1 Satellite Stereo Pair in Himalayan Terrain
High resolution data have high relief displacement in hilly terrains. Development of Digital Elevation model helps to assess bio resources more accurately in such terrains. While estimating bio resources in the Himalayan hilly terrain using multispectral LISS-III data of 23 m spatial resolution, the need for orthorectifcation of satellite data was necessary to correct for spatial distances due ...
متن کاملICESat validation of SRTM C-band digital elevation models
[1] The Geoscience Laser Altimeter System (GLAS) on the Ice, Cloud, and land Elevation Satellite (ICESat) provides a globally-distributed data set well suited for evaluating the vertical accuracy of Shuttle Radar Topography Mission (SRTM) digital elevation models (DEMs). The horizontal error (2.4 ± 7.3 m) and vertical error (0.04 ± 0.13 m per degree of incidence angle) for the ICESat data used ...
