First comprehensive quantification of annual land use/cover from 1990 to 2020 across mainland Vietnam

Abstract Extensive studies have highlighted a need for frequently consistent land cover information for interdisciplinary studies. This paper proposes a comprehensive framework for the automatic production of the first Vietnam-wide annual land use/land cover (LULC) data sets (VLUCDs) from 1990 to 20...
