A Multispectral Image Processing of Spot and TM Landsat data permits to understand the behaviour of the past land cover dynamics; a multi-temporal analysis of Normalized Difference Vegetation and Hydric Stress index, most informative RGB (according to statistical criteria) and Principal Components, points out the importance and the direction of environmental impacts. We gain from the Remote Sensing images new environmental criteria (distance from roads, oil pipe-line, DEM, etc.) which influence the spatial allocation of predicted land cover probabilities. We are comparing the results of different prospective approaches (Markov Chains, Multi Criteria Evaluation and Cellular Automata; Neural Networks) analysing the residues for improving the final model of future deforestation risk. remote sensing change detection GIS predictive models deforestation peten Guatemala environnement Dommages et dégâts causés aux forêts LOMv1.0 collection LOMv1.0 1 LOMFRv1.0 image en mouvement LOMFRv1.0 son LOMFRv1.0 texte v1 LOMv1.0 final LOMv1.0 author BEGIN:VCARD VERSION:3.0 N:;;;; FN:Martin Paegelow ORG: EMAIL;TYPE=INTERNET: END:VCARD 2011-10-05 LOMv1.0 author BEGIN:VCARD VERSION:3.0 N:;;;; FN:Fernanda Renno ORG: EMAIL;TYPE=INTERNET: END:VCARD 2011-10-05 LOMv1.0 author BEGIN:VCARD VERSION:3.0 N:;;;; FN:Nathalie Villa ORG: EMAIL;TYPE=INTERNET: END:VCARD 2011-10-05 URI oai:uved.fr:3386.integrating-remote-sensing-gis-and-prediction-models-to-monitor-the-deforestation-and-erosion-in-peten-reserve-guatemala LOMv1.0 creator BEGIN:VCARD VERSION:3.0 N:;;;; FN: ORG:UVED URL:http://www.uved.fr EMAIL;TYPE=INTERNET: END:VCARD 2011-10-05 LOMv1.0 LOMFRv1.0 SupLOMFRv1.0 fre text/html http://hal.archives-ouvertes.fr/docs/00/37/26/48/PDF/IAMG06_S09_12.pdf 0 LOMv1.0 lecture LOMv1.0 teacher LOMv1.0 learner LOMFRv1.0 licence 0 fre LOMv1.0 no LOMv1.0 yes Licence Creative Commons : Attribution, Pas d'utilisation commerciale, Partage dans les mêmes conditions LOMv1.0 discipline CDD 22e éd.
