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... |

Dupuy, Stéphane; Andriamanga, Andoniaina Valérie; Burnod, Perrine, 2023, "Antananarivo - Madagascar - Land use change map between 2017 and 2022", https://doi.org/10.18167/DVN1/CD2ZTF, CIRAD Dataverse, V1
This map is based on a selection of land use changes, calculated from the crossing of the 2017 and 2022 land use maps. The latters, obtained by supervised classification of satellite images, are: Dupuy, Stéphane; Defrise, Laurence; Gaetano, Raffaele; Burnod, Perrine, 2019, "Antan... |

Dupuy, Stéphane; Andriamanga, Andoniaina Valérie; Burnod, Perrine, 2023, "Antananarivo - Madagascar - build-up area evolutions map between 2003 - 2017 - 2022", https://doi.org/10.18167/DVN1/0EEDAG, CIRAD Dataverse, V1
This map shows the evolution of the built-up area of Antananarivo, capital of Madagascar, between 2003, 2017 and 2022. In ESRI shape vector format, this map results from the crossing of the following land use maps. Dupuy, Stéphane; Defrise, Laurence; Burnod, Perrine, 2019, "Antan... |

Dupuy, Stéphane; Andriamanga, Andoniaina Valérie; Gaetano, Raffaele; Burnod, Perrine, 2022, "Antananarivo - 2022 Land cover map", https://doi.org/10.18167/DVN1/RE1MDM, CIRAD Dataverse, V3
We publish two land cover maps of the city of Antananarivo produced with data acquired in 2022 using a methodology combining machine learning and object-based image analysis (OBIA). This work follows on from work that resulted in a map of the same area in 2017. The maps are produ... |

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... |

Dupuy, Stéphane; Lelong, Camille; Manasse, Marie Esther; Rambao, Jery; Mondésir, Jacques Philémon; Gaetano, Raffaele, 2021, "Nippes - Haïti - 2020, Reference Spatial Database", https://doi.org/10.18167/DVN1/29RZMQ, CIRAD Dataverse, V1
The reference spatial database was created to train an algorithm of supervised classification of satellite images for the production of land cover maps. It is composed of polygons representative of the land cover of the Nippes department in Haïti. The study focuses more especiall... |
