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... |
