Global Land Cover and Land Use 2000 and 2020

Data Download

The Intergovernmental Panel on Climate Change (IPCC) provides guidance on reporting areal extent and change of land cover and land use, requiring the use of estimators that neither over or underestimate dynamics to the degree possible, and that have known uncertainties. The maps provided by GLAD do not have these properties. However, the maps can be leveraged to facilitate appropriate probability-based statistical methods in deriving statistically valid areas of forest extent and change. Specifically, the maps may be used as a stratifier in targeting forest extent and/or change by a probability sample. The team at GLAD has demonstrated such approaches using the GLAD forest loss data in sample-based area estimation (Tyukavina et al., ERL, 2018, Turubanova et al., ERL, 2019, and Potapov et al., RSE, 2019, among others).

Dataset Details

This global dataset is divided into 10x10 degree tiles, consisting of two files per tile. All files contain unsigned 8-bit values and have a spatial resolution of 0.00025° per pixel (~30 meters at the equator). For more information please refer to the above publication and to the data page https://glad.umd.edu/dataset/GLCLUC2020. The same legend is used for all layers. Version 2 is updated to have the additional years of 2005, 2010, and 2015 and with updates to the built-up layers.

Annual maps of land cover and land use (2000, 2005, 2010, 2015, 2020)
Global map with continuous measures of bare ground and tree height inside and outside of wetlands, seasonal water percent, and binary labels of built-up, permanent snow/ice, and cropland.
Net change of land cover and land use between 2000 and 2020 (2000-2020change)
Land cover and land use states of 2020 with tranistions relative to 2000 labeled.
