Data on the extent, patterns, and trends of human land use are critically important to support global and national priorities for conservation and sustainable development. To inform these issues, we created a series of detailed global datasets for 1990, 2000, 2010, 2015, and 2017 to evaluate temporal and spatial trends of land use modification of terrestrial lands (excluding Antarctica). Our novel datasets are detailed (0.09 km2 resolution), temporally consistent (for 1990-2015), comprehensive (11 change stressors, 14 current), robust (using an established framework and incorporating classification errors and parameter uncertainty), and strongly validated. We also provide a dataset for ~2017 with 14 stressors for an even more comprehensive dataset. Also provided is a land/water mask to support subsequent analyses. Please note that the 1990, 2000, 2010, and 2015 change datasets for v1.4 data provide important updates -- analyses that used previous change datasets (i.e. v1-1.3) should be re-run using these ... : The datasets provided here contain revisions to the 1990, 2000, 2010, and 2015 change datasets. Analyses that used previous change datasets (for 1990, 2000, 2010, and 2015) should be re-run using these v1.4 data. The file naming convention for the zip-files that contain the datasets provided here is as follows: gHM_landLakeReservoirOcean300m.zip - contains TIFs at 300 m resolution to represent the following classes: 1=land, 2=lake (natural water bodies), 3=reservoirs (water bodies created by dams), and 4=ocean. gHMv1_300m_1990_change.7z - contains TIFs at 300 m resolution for calculating change between 1990 and 2000, 2010, or 2015. gHMv1_300m_2000_change.7z - contains TIFs at 300 m resolution for calculating change between 2000 and 1990, 2010, or 2015. gHMv1_300m_2010_change.7z - contains TIFs at 300 m resolution for calculating change between 2010 and 1990, 2000, or 2015. gHMv1_300m_2015_change.7z - contains TIFs at 300 m resolution for calculating change between 2015 and 1990, 2000, or 2010. ...
