Global Human Settlement Layer

The Global Human Settlement Layer (GHSL) is a project from the European Commission that creates global geographical data about the evolution of human habitation on Earth. This in the form of population density maps, built-up maps, and settlement maps. This information is produced using new geographic data mining tools and knowledge and analytics based on empirical data.

The GHSL processing framework uses a range of data, including census data, archives of fine-scale global satellite imagery, and voluntarily provided geographic information. Data is processed automatically to produce analytics and knowledge that methodically and objectively describe the existence of people and developed infrastructure. The GHSL maps human presence on Earth, sourcing information from 1975 and up to 2030.
