GHS-BUILT-H ARCTIC R2025A – gridded building height estimates for the Arctic region (2018)
Description
These spatial raster datasets depict the spatial distribution of building heights extracted from a composite of global digital elevation models (DEMs) and Sentinel-2 satellite imagery using image processing and linear regression techniques. The input DEMs are the ALOS World 3D - 30m (AW3D30, timestamp 2006-2011) and the Shuttle Radar Topography Mission 30m (SRTM30, timestamp 2000). The building heights extracted from these sources are updated using shadow markers extracted from more recent Sentinel-2 imagery for the year 2018 (GHS-composite-S2 R2020A). The datasets are published at 100m resolution and consist of two products: 1) Average of the Net Building Height (ANBH), representing the mean building height per grid cell, expressed in meters. 2) Average of the Gross Building Height (AGBH), expressed in terms of cubic meters per surface unit (volumetric built density), while the ANBH is expressed in terms of meters. The data are published at 100m resolution in North Pole LAEA Europe spatial reference system (EPSG:3575).
