Dupuy, Stéphane; Lebourgeois, Valentine; Gaetano, Raffaele, 2023, "Itasy, Vakinankaratra - Madagascar - 2022-2023, Land cover map", https://doi.org/10.18167/DVN1/TKTPCH, CIRAD Dataverse, V1
The land use maps published here were produced for the communes studied by the DINAAMICC project for the period 2022-2023 (based on GPS collected in the field in March 2023). They partially cover the Itasy and Vakinankaratra regions. The reference database used to produce this ma... |

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... |

Tran, Annelise; Mahuzier, Christophe; Morand, Serge, 2022, "Simulated future land cover maps according to different change scenarios, Nan Province, Thailand", https://doi.org/10.18167/DVN1/BRW2DR, CIRAD Dataverse, V1, UNF:6:GfNBdmtXGehqvuCyHeaxrA== [fileUNF]
This dataset holds the results of different simulations of land cover changes over Nan Province, Thailand, up to 2030. ESA global land cover maps (1992-2015) were used as initialization maps (ESA, 2017). A land-cover (LC) change model was constructed from 1992-2015 maps. Three fu... |
