Products Copernicus Waterproofing: degree and changes (every 3 years)

Waterproofing products allow you to visualise the spatial and temporal dynamics of artificialisation of your territories. Waterproof surfaces are defined here as built-up areas for which the original natural or semi-natural surfaces have been replaced by an artificial cover, often impermeable, and generally maintained over long periods of time. The product “Impermeabilisation” provides layers of “Degree of waterproofing” every 3 years since 2006, and layers “Change of waterproofing” between 2 consecutive years. The product ‘Degree of waterproofing’ quantifies the degree of soil sealing per unit surface (pixel of 20 m and aggregated to 100 m from 2006 to 2015, pixel 10 m from 2018), expressed as a % (0 %: permeable surface — 100 %: completely waterproofed surface). The quantitative product “Changement of waterproofing (degree)” is expressed as a % increase or decrease in the degree of waterproofing per pixel (from -100 % to + 100 %), at spatial resolutions of 20 m and aggregated at 100 m (2006 to 2015) and then 10 m (from 2018). The product classified as “Impermeability Change (type)” translates the type of change (without change/new waterproof cover/loss of waterproof cover/impermeability increase/waterproofing decrease) to a spatial resolution of 20 m and aggregated to 100 m (2006 to 2018) and 10 m (from 2018 onwards). The sealing change layers were produced as a difference between the reference years. For displaying WMS streams, the product at 100 m is displayed at low zoom levels and the product at 10 or 20 m at high zoom levels. The product “Impermeabilisation” is supplied by the European Earth Observation Programme Copernicus in raster format.
