Statement

The World Settlement Footprint 3D human settlements mask derived from Sentinel-1 and Sentinel-2 satellite imagery in combination with digital elevation data and radar imagery collected by the TanDEM-X mission.

Description

World Settlement Footprint 3D - Building Area Processing:

Data:

Sentinel-1 and Sentinel-2 satellite imagery at 10 m spatial resolution is used to generate the World Settlement Footprint (WSF) 2019. This layer is supplemented with information on the percent impervious (IMP) surface and serves as a human settlement mask.

The 12 m TanDEM-X Digital Elevation Model and the underlying 3 m Synthetic Aperture Radar (SAR) amplitude images give information on the vertical structuring within the built-up area.

Processing:

The pixel grid of the WSF3D raster was polygonized and the resulting features where attributed with the `Building_Height`, `Building_Area` and the polygon area. Based on the full resolution (zoom level 11), the polygons got dissolved and their attributes aggregated to limit the size of individual tiles in lower zoom levels.

Quality Assurance:

Manually checked against original raster dataset. A comprehensive validation campaign has been undertaken based on 3D building models obtained for 19 regions worldwide (~86,000 km2) and street-view samples indicating the number of floors for >130,000 individual buildings in 15 additional cities.
