Indian Remote Sensing Satellite: Geocoding and DEM Extraction

The present technology does not permit the 7 micro-meter CCD push broom optical sensor to image a region of 70 km. Therefore the IRS-1C satellite uses three separate 4096 CCD push broom optical sensors 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 into a single geometric modelling should give better results (less than one pixel) with also less GCPs.
