The extent of damages due to this hurricane, as well as their impact upon local economy were exceptional. In this framework, a remote sensing project was immediately initiated to provide a large scale evaluation of the damages suffered by the three countries. To reach this objective, new remote sensing products called TmDYNAMICRADAR and TmIDYNAMICOPTICAL products have been designed. These products are, based on using, either radar satellite images, or optical/radar satellite data fusion. The most efficient techniques have been applied to produce these products, thus enabling change detection at a very fine spatial scale (from 20 meters x 20 meters to 10 meters x 10 meters). Project schedule and operations, as well as the validation of its products are reported in this article.

The devastation of Venezuela by heavy rains in December 1999: disaster monitoring and evaluation of damages using ERS InSAR tandem data and SPOT images / E. Nezry (2001)

Concerned about the dramatic extent of this human tragedy, PRIVATEERS N.V. has immediately offered its support to Venezuela. Supported by the French Space Agency (CNES) and the European Space Agency (ESA) who provided the sets of SPOT and ERS SAR (Synthetic Aperture Radar) images acquired before and after the disaster, this project aims to the provision of cartographic maps designed to assess the situation and to help with the rehabilitation of the country. These maps are designed to be easily exploitable by local photo-interpreters.
