FUSION OF SAR AND OPTICAL IMAGERY FOR STUDYING THE ECOEPIDEMIOLOGY OF VECTOR-BORNE DISEASES IN TROPICAL COUNTRIES

摘要

public health issue worldwide. Other mosquito-bornediseases affect more and more countries and people,with effects on health which are not all identified yet.Recent developments in the field of remote-sensingallow to consider overriding the existing limits ofstudying such diseases in tropical regions, where cloudand vegetation cover often prevent to identify andcharacterize environmental features.We highlight the potential of SAR-optical fusion for themapping of land cover, the identification of wetlands,and the monitoring of environmental changes indifferent habitats related to vector-borne diseases in theFrench Guiana - Brazil cross-border area. This study isthe foundation of a landscape-based model of malariatransmission risk. Environmental factors, together withepidemiological, socio-economic, behavioral,demographics, and entomological ones, contribute toassess risks related to such pathologies and supportdisease control and decision-making by local publichealth actors.
