%X This study had as a goal to use geo-technologies in the identification of environmental factors associated with the space distribution of American visceral leishmaniasis in the municipality of Conde, Bahia, Brazil. During the period of study, 42.6% of the reported cases occurred in localities with normalized difference vegetation indexes of 0.67 to 0.75. The digital elevation model showed an inverse relationship between altitude and disease, suggesting that there is a higher concentration of flebotomines in the low-lying areas of the municipality. The land cover and land use map illustrated the predilection of the vector for areas with sparse vegetation and the tendency of this disease urbanization. This study points out the necessity for the development of multidisciplinary research regarding landscape epidemiology in association with geo-technologies for the identification of the factors associated to endemics and its risk areas. Objetivou-se com este estudo utilizar as geotecnologias na identifica  o de fatores ambientais associados ¨¤ distribui  o espacial da Leishmaniose Visceral Americana no munic¨ªpio de Conde, Bahia. No per¨ªodo de estudo, 42,6% dos casos registrados ocorreram em localidades com ¨ªndice de Vegeta  o por Diferen a Normalizada variando de 0,67 a 0,75. O Modelo Digital de Terreno mostrou rela  o inversa entre altitude e doen a, o que sugere maior concentra  o de flebotom¨ªneos em ¨¢reas mais baixas do munic¨ªpio. O mapa de cobertura vegetal e de uso do solo ilustrou a predile  o do vetor por ¨¢reas de vegeta  o n o muito densas, e a tend¨ºncia de urbaniza  o da doen a. Este estudo aponta a necessidade da realiza  o de pesquisas multidisciplinares que contemplem a epidemiologia paisag¨ªstica em associa  o com as geotecnologias na identifica  o de fatores associados ¨¤ endemia e suas ¨¢reas de risco.
