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; 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... |
