摘要：IGN has a long experience in the field of DEM extraction from digital space borne images such as SPOT images. As a sub contractor of CNES during the in - flight commissioning of SPOT5 HRS instruments for the evaluation of DEM extraction capability, IGN Espace has been further involved in the management of HRS SAP program. C - SAP program gives us an opportunity to apply our know - how acquired in the field of geometric image quality as a princ ipal investigator over the Salon test site. The first activity related to C - SAP will be to upgrade our image processing software (named GeoView) w ith the CARTOSAT1 model and, with bundle adjustment using GCP s completed with tie points, optimize the physic al models associated to the images provided within the SAP program over our Salon test site. Then we will further investigate the capability of CARTOSAT1 imagery for DEM extraction, paying a particular attention to the geometric image quality of the image data, and the rendition of global and local relief, through comparison with available large - scale DEMs. The preliminary results w ill be presented in collaboration with SPOT IMAGE during the special seminar organised in India
