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 production of the High Resolution Imperviousness products was coordinated by the European Environment Agency in the frame of the EU Copernicus programme. A verification of the Imperviousness layer was performed by the National Land Survey of Iceland during autumn of 2018 and the data and resulting report are made available on the NLSI websites.

The combined Water and Wetness product is a thematic product showing the occurrence of water and wet surfaces over the period from 2009 to 2015. Two products are available: o The main Water and Wetness (WAW) product with defined classes of (1) permanent water, (2) temporary water, (3) permanent wetness and (4) temporary wetness. o The additional expert product: Water & Wetness Probability Index (WWPI) The products show the occurrence of water and indicate the degree of wetness in a physical sense, assessed independently of the actual vegetation cover and are thus not limited to a specific land cover class and their relative frequencies. A verification of the Water and Wetness layer was performed by the National Land Survey of Iceland during autumn of 2018 and the data and resulting report are made available on the NLSI websites.

The dataset presents three layers of geothermal data from Iceland based on "Atlas of Geothermal Resources in Europe" (2002). Heat-flow density, Temperature at 1000 meters and Temperature at 2000 meters (1:10 000 000).

The main high resolution grassland product is the Grassland layer, a grassland/non-grassland mask for the EEA39 area. This grassy and non-woody vegetation baseline product includes all kinds of grasslands: managed grassland, semi-natural grassland and natural grassy vegetation. It is a binary status layer mapping grassland and all non-grassland areas in 20m and (aggregated) 100m pixel size. Two additional (expert) products complete the high resolution grassland product: the Ploughing Indicator (PLOUGH) and the Grassland Vegetation Probability Index (GRAVPI). While the PLOUGH concentrates on historic land cover features with the aim to indicate ploughing activities in preceding years, the GRAVPI provides a measure of classification reliability. GRAVPI is a 20m pixel size product, mapping on a range of 1-100 the class probability. PLOUGH is a 20m pixel size additional product, mapping from 1-6 the number of years since the last indication of ploughing. A verification of the Grassland layer was performed by the National Land Survey of Iceland during autumn of 2018 and the data and resulting report are made available on the NLSI websites.
