Topics: , ,
The map shows the density of soil sealing in 2012, based on a 10 km2 reference grid. Green and light orange colors show areas with no or very limited sealing, while red and dark red colors show highly to fully sealed grid cells (mainly urban areas).

information.png Methodology:

The map is based on aggregated data, derived from the original Imperviousness change 2009-2012, 100m dataset and status layer. The original 100m grid cells were aggregated to 1km and later 10km to derive overview maps on imperviousness.

information.png Units:

Average sealing density (in %) per 10km grid cells.

Based on data

Copernicus Land Monitoring Service - High Resolution Layers - Imperviousness Copernicus Land Monitoring Service - High Resolution Layers - Imperviousness The high resolution imperviousness products capture the percentage and change of soil sealing. Built-up areas are characterized by the substitution of the original (semi-) natural land cover or water surface with an artificial, often impervious cover. These artificial surfaces are usually maintained over long periods of time. A series of high resolution imperviousness datasets (for the 2006, 2009, 2012 and 2015 reference years) with all artificially sealed areas was produced using automatic derivation based on calibrated Normalized Difference Vegetation Index (NDVI). This series of imperviousness layers constitutes the main status layers. They are per-pixel estimates of impermeable cover of soil (soil sealing) and are mapped as the degree of imperviousness (0-100%). Imperviousness change layers were produced as a difference between the reference years (2006-2009, 2009-2012, 2012-2015 and additionally 2006-2012, to fully match the CORINE Land Cover production cycle) and are presented 1) as degree of imperviousness change (-100% -- +100%), in 20m and 100m pixel size, and 2) a classified (categorical) 20m change product.
Copernicus 10 km grid Copernicus 10 km grid Hosted on land.copernicus.eu. The data used for the European overview maps as part of the indicator publication, are based on the same original 100m Imperviousness change products, aggregated first to 1km, then to 10km grid size for overview map production.
