  • Geometric and radiometric restoration of ERS-1 SAR data for tropical forest mapping over mountainous terrain. A case study over 'Les Monts des Dans' - Cote d'Ivoire


This paper deals with the engineering issues related to the impact of topography on the geophysical information extraction in the context of the pre-operational strategy of the JRC-ESA TREES (Tropical Ecosystem Environment Observations by Satellites) project. A test case was performed on a well characterized site in West Africa and the performance and the error budget of a methodology based on georeferencing technology was assessed. The problems related to the error characterization of the input products are highlighted and it is shown to what extent the impact of topography can be characterized and accounted for. Conclusions are drawn as to the applicability of such an approach in the thematic context of the tropical forest mapping.
