Télédétection SAR interférométrique de zones urbaines en bande L à partir de l'utilisation des techniques d'analyse spectrale polarimétriques et multi-bases

In this thesis, spectral analysis techniques are generalized to process polari-metric multibaseline interferometric SAR data. These polarimetric arraysignal processing algorithms are described in a rigorous mathematical wayand applied to urban areas. They permit the estimation of the reflectorheight, the scattering mechanism, and the polarimetric reflectivity. Fromsingle...

Utilisation des représentations spatiales en gestion intégrée des zones côtières

This article aims to study how mapping contributes to organize and implement Integrated Coastal Zone Management projects. In order to observe the use of spatial representations and better understand the stakeholder’s mapping practices a qualitative methodology is used. The results show that mapping was mostly used to structure and stabilize the actor’s network. MOTS-CLES : représentations spati...

Information Discovery in Ambiguous Zones of Research

Electronic environments for information discovery are considered in relation to open-ended and dynamic research practices in the humanities, but a system suitable for these scholars would have many other applications as well. Considerations of flexible electronic environments that would support research are based on the holistic view of information processes and the requirements that informatio...
