Imperviousness and imperviousness change The imperviousness indicator is defined as the yearly average imperviousness change between two reference years, as measured by imperviousness change products. The change is aggregated for a certain reference unit and expressed as relative to the size of that unit (as a percentage). The imperviousness change value for a 100 m raster cell is based on 100 m imperviousness change products. The default reference unit is the country, but the indicator can be aggregated based on different spatial units. For example, for a certain country, a n imperviousness indicator value of 0.2 %, means that on average, an additional 0.2 % of this country's area has been sealed annually during the period between the two reference years in question. If above a certain rate of increase (threshold values) , this value can be used as a warning sign. The aggregation of imperviousness values to reference units is performed using the LEAC CUBE method.

The change is aggregated for a certain reference unit, and expressed and relative to the size of said unit (as a percentage). The imperviousness change value for a 100 m raster cell is based on 100 m imperviousness change products, corresponding to the difference in imperviousness status values (e.g. IMD2009-IMD2006). The default reference unit is the country, but the indicator can be aggregated based on different spatial units. For example, for a certain country, a n imperviousness indicator value of 0.2 %, means that an additional 0.2 % of this country's area has been sealed annually during the period between the two reference years in question. If above a certain rate of increase (threshold values) , this value can be used as a warning sign. The aggregation of imperviousness values to reference units is performed using the LEAC CUBE method.
Land take This indicator looks at the change in the amount of agricultural, forest and other semi-natural and natural land taken by urban and other artificial land development. It includes areas sealed by construction and urban infrastructure, as well as urban green areas, and sport and leisure facilities. The main drivers of land take are grouped in processes resulting in the extension of: housing, services and recreation; industrial and commercial sites; transport networks and infrastructures; mines, quarries and waste dumpsites; construction sites.
Land take The land take indicator address the change in the area of agricultural, forest and other semi-natural land “taken” for urban and other artificial land development (hence the name “Land take”). Land take includes areas sealed by construction and urban infrastructure, as well as urban green areas, and sport and leisure facilities. The main drivers of land take are grouped in processes resulting in the extension of: housing, services and recreation; industrial and commercial sites; transport networks and infrastructures; mines, quarries and waste dumpsites; construction sites. Note: The reported land take change relate to the extension of urban areas and may also include parcels which were not sealed (e.g. urban green areas, sport and leisure facilities). This is, in particular, the case for discontinuous urban fabric, which is considered as a whole. Similarly, monitoring the indicator with satellite images leads to the exclusion of most linear transport infrastructures, which are too narrow to be observed directly.
