The Global Land Cover Estimation (GLanCE) project provides high-quality long-term records of land cover and land cover change at 30 m spatial resolution for the 21st century using the Landsat archive. The GLanCE land cover classification scheme is designed to be compatible with common land cover classification systems such as the IPCC land use categories for greenhouse gas inventory reporting and the FAO Land Cover Classification System (LCCS). As part of the GLanCE project, we present a new land cover training database that is designed to provide global coverage, ensure accuracy of land cover labels at 30 m spatial resolution, cover nearly four decades, and produce a geographically dense dataset.
This repository contains a Cloud-Native Geospatial GeoParquet version as well as a GeoJSON version of the data. You can use the BROWSE link on the left hand side to navigate to the data and download it. You can also access the S3 bucket directly with S3 tools (aws cli, boto3, etc); the S3 URI is s3://us-west-2.opendata.source.coop/boston-university/bu-glance/
