Dupuy, Stéphane; Lelong, Camille; Gaetano, Raffaele; Villers, Alexandre, 2024, "Occupation du sol - Mayotte - Carte de 2023", https://doi.org/10.18167/DVN1/CTNRHW, CIRAD Dataverse, V1
Nous diffusons des cartes d'occupation des sols de l'ile de Mayotte produites en 2023 en utilisant une méthodologie combinant l'apprentissage automatique et l'analyse d'images satellites basée sur les objets (OBIA). Ces travaux ont été réalisé dans le cadre du projet BIOTAMAYA (f... |

Gaetano, Raffaele; Dupuy, Stéphane; Lelong, Camille, 2021, "Nippes - Haïti - 2020, Land Cover Map at high spatial resolution", https://doi.org/10.18167/DVN1/ZAN2WN, CIRAD Dataverse, V1
The maps were produced with iota2 processing chain, developed in the framework of the activities of the "Land Use" Scientific Expertise Centre of the Theia Data and Services Center. They are distributed in raster TIFF format. IOTA2 produces land cover maps by classifying satellit... |

Dupuy, Stéphane; Lelong, Camille; Gaetano, Raffaele, 2021, "Nippes - Haïti - 2020, Land Cover Map at very high spatial resolution", https://doi.org/10.18167/DVN1/QOLTTE, CIRAD Dataverse, V1
The maps were produced with the Moringa chain developed by CIRAD (UMR TETIS). They are distributed in ESRI SHAPE vector format. The Moringa chain produces land cover maps by classifying satellite images. It implies a time series of Sentinel 2 images, a Digital Terrain Model, a ve... |
