La base de données de référence a été créée pour entrainer un algorithme de classification supervisé d'images satellites pour la production de cartes d'occupation du sol. Il s'agit de polygones représentatifs de l'occupation du sol de l'ile de Mayotte. La table attributaire conti... |
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, 2023, "Mayotte - 2022 - DHM from Pleiades stereoscopic images", https://doi.org/10.18167/DVN1/4EAKVD, CIRAD Dataverse, V2
The data published here are derived from Pleiades images acquired by the Dinamis system. These data are produced for the Biotamaya project. - The DSM (Digital Surface Model) is calculated from Pleiades images acquired in stereoscopic mode. The images were acquired in 2022 (betwee... |
Bley-Dalouman, Hélène; Broust, François; Tran, Annelise, 2023, "Forest map, Western Highlands region, Reunion Island", https://doi.org/10.18167/DVN1/LXXO9Y, CIRAD Dataverse, V1
A land cover map of forests of the Western Highlands region, Reunion Island was produced using a cloudless very high spatial resolution Pleiades image acquired on 31 May 2020. The final map was obtained through a supervised object-based classification of the Pleiades image using... |
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... |
Lelong, Camille; Herimandimby, Hasina, 2022, "Very high spatial resolution land use / land cover map of a 84km2 part of the Vavatenina District, Analanjirofo Region, Madagascar, 2019", https://doi.org/10.18167/DVN1/KDNOV4, CIRAD Dataverse, V1
This map gives the spatial distribution of the main agricultural systems and land uses present in an area of study of landscape dynamics in Madagascar. It consists of an area of 84 square kilometers located at the West of Vavatenina town, in the Analanjirofo Region, on the North-... |
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... |
