From hyperspectral satellite images to decision processes: a user-oriented approach
21 July 2003
The aim of our study is to develop products and services for coastal zone management based on the exploitation of hyperspectral sensors as CASI, MeRIS or Hyperion. Bathymetry, seabed features map and water quality products are hardly required for a more effective monitoring and management of such sensitive and dynamic areas. Data correction from atmosphere, sunglint and attenuation effects are presented as well as products previously cited. These products provided by different sensors will be integrated in a prototype tool dedicated to coastal decision-makers. Our user-oriented approach should provide valid and systematic information on seashore to complete in situ measurements. This approach will takes advantage of the temporal, swath and spectral resolution of MERIS sensor and the spectral and spatial resolution of Hyperion or CASI. Fusion tool will be integrated in the prototype in order to improve MeRIS resolution and to keep its swath and its temporal repetitivity.
