Dataset description

The GLAD Global Land Cover and Land Use Change dataset quantifies changes in forest extent and height, cropland, built-up lands, surface water, and perennial snow and ice extent from the year 2000 to 2020 at 30-m spatial resolution. The global dataset derived from the GLAD Landsat Analysis Ready Data. Each thematic product was independently derived using state-of-the-art, locally and regionally calibrated machine learning tools. Each thematic layer was validated independently using a statistical sampling.

Data Download
Dataset already hosted as GEE asset, but with each epoch separated. The time series can be combined into a single image collection as follow:

var landmask = ee.Image("projects/glad/OceanMask").lte(1)

var m00 = ee.Image('projects/glad/GLCLU2020/v2/LCLUC_2000').updateMask(landmask).set('year', 2000);
var m05 = ee.Image('projects/glad/GLCLU2020/v2/LCLUC_2005').updateMask(landmask).set('year', 2005);
var m10 = ee.Image('projects/glad/GLCLU2020/v2/LCLUC_2010').updateMask(landmask).set('year', 2010);
var m15 = ee.Image('projects/glad/GLCLU2020/v2/LCLUC_2015').updateMask(landmask).set('year', 2015);
var m20 = ee.Image('projects/glad/GLCLU2020/v2/LCLUC_2020').updateMask(landmask).set('year', 2020);

// Create the image collection
var imageCollection = ee.ImageCollection([m00, m05, m10, m15, m20]);

The change between 2000 and 2020 can be assessed here:
var change = ee.Image('projects/glad/GLCLU2020/v2/LCLUC').updateMask(landmask);
