Indian Remote Sensing Satellite: Geocoding and DEM Extraction
نویسندگان
چکیده
The present technology does not permit the 7-μm CCD push broom optical sensor to image a region of 70 km. Therefore the IRS –1C satellite use three separate 4096 CCD push broom optical sensor resulting in three array images. Two different methods to ortho-rectify and mosaic the three IRS-1 array images are presented. Results using the CCRS modelling show an accuracy of about one pixel. Future research at CCRS to integrate the parameters of the three sensors in to a single geometric modelling should give better results (less than one pixel) with also less GCPs.
