Topics:
Shapefile showing using a 10km reference grid, the imperviousness density 2009 status layer. The dataset is derived from aggregating the original Imperviousness 2009 status layer, 100m spatial resolution, copyright by the Geoland2 project consortium.

Indicator Specification

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 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.
