The map shows the difference of the years 2015 and 2009 and presents the increase in fragmentation in that period. The original 100m values were resampled to a 5 km grid for visualisation purposes.

information.png Methodology:

Fragmentation as a result of urban and transport infrastructure expansion is monitored using the Copernicus Imperviousness and the TeleAtlas road network datasets.

Additional information

The map presents fragmentation increase after outliers have been removed (less than 5 percentile and more than 90 percentile). Fragmentation was calculated for the years 2009, 2012 and 2015 using the effective mesh size method.

The map covers the EEA-39 member countries. Due to poor data coverage of fragmentation geometries for this period the following countries have been omitted: Cyprus, Iceland, Albania, Kosovo, Serbia, Cyprus, North Macedonia, Romania, Bosnia and Herzegovina and Turkey.

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.
