High Resolution Layer: Imperviousness Density 2009 (raster 100m) accounting layer, Jan. 2019
The current dataset was derived from original Copernicus High Resolution Layer Imperviousness Density 2009 product product for the purposes of imperviousness indicator (LSI002) calculations within the EEA LEAC CUBE environment. The dataset is also input to the imperviousness indicator itself.
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. The latest version (published: 15/01/2019) of 100m resolution imperviousness status layers represents a time series consistent with 100m resolution imperviousness change layers - the cell by cell difference of the degree of imperviousness status corresponds to the degree of imperviousness change. The production of the High Resolution Imperviousness products was coordinated by the European Environment Agency in the frame of the EU Copernicus programme.

The imperviousness HRL captures the spatial distribution of artificially sealed areas, including the level of sealing of the soil per area unit. The separation of artificially sealed areas from non-sealed represents a kind of stratification and is based on a list of included / excluded elements. The level of sealed soil (imperviousness degree 1-100%) is produced using a semi-automated classification, based on calibrated NDVI. Find more detail in the technical document.
The latest version of imperviousness products (published: 15/01/2019) were significantly improved compared to the previous versions - see details at
https://land.copernicus.eu/pan-european/high-resolution-layers/imperviousness
The current resource was derived for the purposes of imperviousness indicator LSI002 calculations within EEAs LEAC CUBE environment. The original 100m resolution imperviousness status product was modified:
- All cells in status layers were excluded (set to "No data") if 254 (unclassifiable) or 255 (out of area) values appeared in any of the status layers of the time series (2006, 2009, 2012, 2015) at the same cell location.
- Original imperviousness degree values (0-100%), were modified to values representing sealed area in sqm within the 1ha cells (0-10.000 m2).
Detailed information about the LSI002 indicator can be found in the interactive data viewer "Imperviousness in Europe" on https://www.eea.europa.eu/data-and-maps/dashboards/imperviousness-in-europe. The report available on https://forum.eionet.europa.eu/etc-urban-land-and-soil-systems/library/10.-ap-2018/1.8.2.7-support-time-series-update-imperviousness-indicator-lsi002 (Eionet account required) provides a summary of the update and publication of the imperviousness indicator, changes on the 2006-2015 time series, as well as the quality assessment and testing of the robustness of the indicator.
