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).

Metadata

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

Data Copernicus Land Monitoring Service - High Resolution Layers - Imperviousness The imperviousness products capture the percentage and change of soil sealing. Sealed/Impervious 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. The imperviousness HRL captures the spatial distribution of artificially sealed areas, including the level of sealing of the soil per area unit. The level of sealed soil (imperviousness degree 1-100%) is produced using a semi-automated classification, based on calibrated NDVI. Imperviousness data is available for the reference years 2006, 2009, 2012, 2015, and 2018, and contains two types of products: 1. Status layers Imperviousness Density (IMD) The percentage of sealed area is mapped for each status layer for any of the 5 reference years (e.g. degree of Imperviousness 2012). The status layers are available in 10m spatial resolution (2018), 20m spatial resolution (2006-2015), and as aggregated 100m products. Impervious Built-up (IBU) This product shows built-up areas, the part of the sealed surfaces where buildings can be found. Built-up areas are a sub-group of the sealed areas. It refers to areas where above-ground building constructions can be found. In contrast to the Imperviousness characterized by a continuous range of imperviousness measurements, built-up in the HRL 2018 is a binary product, expressed as built-up or non-built-up areas. This product is new for the 2018 mapping campaign and is available in 10 meter resolution, as well as a 100 meter aggregated version called Share of Built-up (SBU) 2. Change layers Two types of change products are available for each of the 3-year periods between the 5 reference years (2006-2009, 2009-2012, 2012-2015, 2015-2018), and in addition, for the period 2006-2012 (that is in line with the 6-year period between two Corine Land Cover products): a) A simple layer mapping the percentage of sealing increase or decrease for those pixels that show real sealing change in the period covered. This product is available in 20m and 100m pixel size. b) A classified change product that maps the most relevant categories of sealing change (unchanged no sealing, new cover, loss of cover, unchanged sealed, increased sealing, decreased sealing). This product is available in 20m pixel size only.
Data 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.
