The GHS-LAND spatial raster dataset depicts the distribution of the land surfaces estimates by joint assessment of satellite image data and Open Street Map (OSM) data. The main satellite data used in input is the GHS Composite-S2, that corresponds to global cloud-free pixel based composite created from the Sentinel-2 data archive (Level L1C) available in Google Earth Engine for the period January 2017 - December 2018 available at 10m resolution and reporting about the R,G,B and NIR bands of the multispectral instrument on board the Sentinel satellite platform. The gaps of these data for covering the expected global landmass were filled using the panchromatic band of the Landsat images used to support the epoch 2014 of the GHS-BUILT-S. The remaining gaps where no S2 data and no Landsat data were available, were filled by direct imposing of the OSM data if available.
