DEM generation using Cartosat-1 stereo data: issues and complexities in Himalayan terrain
High-altitude Himalayan terrain exhibits extreme geometric distortion along north-facing (dilation) and south-facing (compression) slopes as observed in satellite stereo data with high look angles. In the present study, Cartosat-1 stereo pairs have been used for generating Digital Elevation Model (DEM) using Differential Global Positioning System based Ground Control Points. DEM quality assessm...
متن کاملAnalysis of Dem Generated Using Cartosat-1 Stereo Data over Mausanne Les Alpiles – Cartosat Scientific Appraisal Programme (csap Ts – 5)
The high-resolution Cartosat-1 stereo image data is expected to have significant impact in topographic mapping and watershed applications. The objective of the present investigation is to make an assessment of the potential of the Cartosat-1 data in topographic mapping and generation of DEMs in operational mode using COTS packages. The assessment is based on the entropy analysis of the fore/aft...
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 کاملPrecision Analysis of Dem Obtained from Cartosat Stereo-couple
The whole process of DEM creating on the basis of stereo images from Cartosat is presented in the paper. Digital correlation of images (matching) in terms of appropriate parameters selection is analyzed because of the 10-bit radiometric resolution. The precision analysis is based on the comparison of DEM generated from Cartosat stereo-couple and DEM obtained from DTED level 2. Additionally, 3-k...
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...
