Abstract

Presents a rigorous, high-precision model for geometric orthorectification of Declassified Intelligence Satellite Photography (DISP) imagery for the generation of a seamless, full-coverage mosaic of the Greenland ice sheet. This model integrates the bundle adjustment method and satellite orbital parameters, solving for interior orientation (including lens distortion) and exterior orientation parameters simultaneously. Two full-coverage mosaics of Greenland using 24 DISP acquired in 1962 and 36 images acquired in 1963 were created. The average planimetric accuracy (relative to SAR Mosaic) is about 168 m in flat areas, 186 m in mountainous areas. The two mosaic products have been delivered to the US National Snow and Ice Data Center (NSIDC) for use by the research community.
