Abstract : As part of a contract between the Societe Europeenne de Propulsion (SEP) and the Space Research and Remote Sensing Organization (SPARRSO) aiming at the implantation of a SPOT receiving ground station in Bangladesh, an airborne remote sensing experiment was carried out in January 82. Its purpose was to allow the generation of Spot-simulated data over a set of given areas. The interpretation of the data collected was focused on three main topics i.e.rice, coastal areas, cane-sugar. During the campaign, seven zones were covered with the aircraft flying at an altitude of either 3 500 m (11 500 ft) or 7 000 m (23 000 ft). Data from the Daedalus scanner (visible and near infrared bands) were recorded while infrared color photographs were taken. Daedalus data were collected in order to generate radiometric Spot simulations while the photographs are necessary for the geometric simulations. The geometric approach is aimed at simulating SPOT parameters which affect the geometrical quality of the images collected by the satellite. These parameters include satellite position and attitude, earth rotation and sphericity, instrument geometry, type of projection, and stereoscopy effect. The radiometric approach is aimed at simulating SPOT parameters which affect radiometry (spectral band, the line of sight, local time, the satellite track orientation ...). This paper deals with the first results gained from the interpretation of the data collected from the scanner over one of the study areas, namely the Hail Haor area which is located south of Syhlet.
