[Termes IGN] valeur propreRésumé : (Auteur) Within the last decade several studies using polarimetric SAR data for bio-/geo-physical feature extraction have been reported and have significantly improved the understanding of polarimetric scattering mechanisms. In a comparative view, the approach presented here, which is based on Shane Cloud's Decomposition Theorem, seems to be most promising : the Entropy H and Angle Classification has been extended by using not only the parameters H and but also the first eigenvalue1. A big advantage of this approach is the high correlation between its results and the physical properties of different landsurface materials, which makes this recently adapted method well-suited for both supervised and automated landcover classification. It is also most useful for the derivation of topographic as well as thematic map information, the scale naturally depending on the sensor's spatial resolution. The well-known DLR Oberpfaffenhofen study site in southern Germany served as a testbed for the exploitation of spaceborne SIR-C/X-SAR data and of L-band data from DLR's airborne experimental ESAR. For validation purposes the classification results have been high-precision geocoded and compared to both ground truth and recent map data, also superimposing the digital national topographic geodata of Germany, ATKIS. The classification proved to be of extraordinary accuracy, as far as can be judged by visual inspection. An exact quantification is underway. The approach presented is being further developed and will - in contrast to the flat test-site used so far - be applied to data flown by a new airborne SAR sensor over mountainous terrain at the northern rim of the Bavarian Alps. First results in this respect look very promising.

[Termes IGN] système multi-agentsIndex. décimale : 50.00 Environnement Résumé : (auteur) This book which is written by recognised specialists of ecosystems and environment modeling is dedicated to students and scientists concerned by environment questions who wish to be able to model or to understand models and to have clear insights into the different systemic approaches of ecosystems and environment modelling. Particularly, they will find pedagogic descriptions and useful references about climatic models, forest evolutions, dynamics of populations, utilisation of remote sensing for biosphere modeling, knowledge bases and reasoning mechanisms use for environment and ecosystems management, application of artificial intelligence as multi-agents simulations to try to describe ant to validate agents actions' considering parallel artificial worlds, applications of inverse methods (sentinel method) to retrieve pollutant sources. The techniques of scaling and fuzzy sets applications necessary to interpret environment data and some cautions in data manipulations due to possible ambiguities are also presented. The reader would have to realize that in a real interdisciplinary approach of environment which is considered now to be absolutely necessary to be able to respond to environment questions with a maximum of confidence in the different concerned domains, these different types of techniques and models would have to be necessary coupled and to interact in what is said complex systems modelling: these kind of models are the tools to try to represent and to imitate the real world for cognition and to give the probable evolutions of such systems which are the required evolution scenarios.
