Paper Abstract

Temporal monitoring using remote sensing for topographic mapping requires continuous acquisition of image data. In many countries, but especially in the human Tropics, the heavy cloud cover is a major drawback for visible and infrared remote sensing. The research project presented in this paper uses the idea of integrating data from optical and microwave sensors using digital image fusion techniques to overcome the cloud cover problem. Additionally the combination of radar with optical data increases the interpretation capabilities and the reliability of the results due to the complementary nature of microwave and optical images. While optical data represents the reflectance of ground cover in visible and near-infrared, the radar is very sensitive to the shape, orientation, roughness and moisture content of the illuminated ground objects. This research investigates the geometric aspect of image fusion for topographic map updating. The paper describes experiences gained from an area in the north of The Netherlands (`Friesland') as calibration test site in comparison with first results from the research test site (`Bengkulu'), located on the south west coast of Sumatra in Indonesia. The data used for this investigated was acquired by SPOT, Landsat, ERS-1 and JERS-1.
