In this context, based on a knowledge-based model, a normalized landscape-based hazard index (NLHI) was established at a local scale, using a 10 m spatial resolution forest vs. non-forest map, landscape metrics and a spatial moving window. Such an index evaluates the contribution of landscape to the probability of human-malaria vector encounters, and thus to malaria transmission risk. Since the knowledge-based model is tailored to the entire Amazon region, such an index might be generalized at large scales for establishing a regional view of the landscape contribution to malaria transmission. Thus, this study uses an open large-scale land use and land cover dataset (i.e., the 30 m TerraClass maps) and proposes an automatic data-processing chain for implementing NLHI at large-scale. First, the impact of coarser spatial resolution (i.e., 30 m) on NLHI values was studied. Second, the data-processing chain was established using R language for customizing the spatial moving window and computing the landscape metrics and NLHI at large scale. This paper presents the results in the State of Amapá, Brazil. It offers the possibility of monitoring a significant determinant of malaria transmission at regional scale. specialized PALUDISME TRANSMISSION ANALYSE SPATIALE GESTION DE L'ENVIRONNEMENT DEFORESTATION CARTOGRAPHIE AUTOMATIQUE BRESIL GUYANE FRANCAISE AMAZONIE AMAPA 052ANOPAL03 122TRAI 2 4 art. no 37 [11 en ligne] 2017 2306-5729 https://www.documentation.ird.fr/hor/fdi:010071100 10.3390/data2040037 2306-5729 [F B010071100] https://www.documentation.ird.fr/hor/fdi:010071100 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers17-11/010071100.pdf IRD - Base Horizon / Pleins textes 2017-11-12 2023-07-11 fdi:010071100 fre
