[dataset] Annual dynamics of global land cover and its long-term changes from 1982 to 2015

With the latest version of GLASS (Global Land Surface Satellite) CDRs (climate data records) from 1982 to 2015, the authors built the first record of 34-year-long annual dynamics of global land-use/land-cover (LULC) (GLASS_GLC) at 5 km resolution using Google Earth Engine platform. Compared to earlier global LULC products, GLASS-GLC is characterized by high consistency, more detail, and longer temporal coverage.
