Svæða-, staðar- og farvegaskipting fyrir ofanflóð í samræmi við ofanflóðaskráningarkerfi Veðurstofu Íslands. Um er að ræða stigskiptingu (hierarchy) þar sem landinu er skipt niður í staði, hverjum stað svo niður í svæði og innan svæða eru svo afmarkaðir algengir farvegir ofanflóða.

Þekja (layer) j100v_austurland_skridur_1utg_li: Lagið sýnir útlínur stærstu framhlaupa á svæðinu. [The layer shows the outlines of the largest landslides of the area.]

Eldissvæði er svæði sem úthlutað er rekstarleyfishafa. Rekstrarleyfishafi hefur þá heimild til að hafa eldisbúnað til að ala fisk innan þess svæðis skv. skilyrðum rekstrarleyfisins.

Útlínur dregnar eftir uppréttum Sentinel-2 gervihnattamyndum. Uppréttar loftmyndir frá Loftmyndum ehf. voru einnig notaðar á nokkrum stöðum.

The high resolution forest product consists of three types of (status) products and additional change products. The status products are available for the 2012 and 2015 reference years: 1. Tree cover density providing level of tree cover density in a range from 0-100% 2. Dominant leaf type providing information on the dominant leaf type: broadleaved or coniferous 3. A Forest type product. The forest type product allows to get as close as possible to the FAO forest definition. In its original (20m) resolution it consists of two products: 1) a dominant leaf type product that has a MMU of 0.5 ha, as well as a 30% tree cover density threshold applied, and 2) a support layer that maps, based on the dominant leaf type product, trees under agricultural use and in urban context (derived from CLC and high resolution imperviousness 2009 data). For the final 100m product trees under agricultural use and urban context from the support layer are removed. The high resolution forest change products comprise a simple tree cover density change product for 2012-2015 (% increase or decrease of real tree cover density changes). A verification of the Tree Cover Density layer was performed by the Institute of Nature Research during autumn of 2018 and the data and resulting report are made available on the NLSI websites.

Þekja [layer] j100v_vesturgosbelti_jardgrunnur_1utg_fl: Jarðgrunnsgögn af Vesturgosbelti Íslands. [Surface deposits of the Western Volcanic Zone of Iceland.] Laus setlög, svo sem jökulgarðar og árset. [Unconsolidated sediments including glacial morianes and river sediments.]

Slope aspect map of Iceland. This tool calculates slope aspect (i.e. slope orientation in degrees clockwise from north) for each grid cell in an input digital elevation model (DEM). “Aspect values indicate the directions the physical slopes face.” The values of each cell in the output raster indicate the compass direction the surface faces at that location. It is measured clockwise in degrees from 0 (due north) to 360 (again due north), coming full circle. Flat areas having no downslope direction are given a value of -1.

Corine Land Cover (CLC) 2018 and CLC change 2012-2018 are two of the datasets produced within the frame of the Initial Operations of the Copernicus programme (the European Earth monitoring programme previously known as GMES) on land monitoring.Corine Land Cover (CLC) provides consistent information on land cover and land cover changes across Europe. This inventory was initiated in 1985 (reference year 1990) and established a time series of land cover information with updates in 2000, 2006. 2012 and now 2018. CLC products are based on photointerpretation of satellite images by national teams of participating countries - the EEA member and cooperating countries – following a standard methodology and nomenclature with the following base parameters: 44 classes in the hierarchical three level Corine nomenclature; minimum mapping unit (MMU) for status layers is 25 hectares; minimum width of linear elements is 100 metres; minimum mapping unit (MMU) for Land Cover Changes (LCC) for the change layers is 5 hectares. The resulting national land cover inventories are further integrated into a seamless land cover map of Europe. Land cover and land use (LCLU) information is important not only for land change research, but also more broadly for the monitoring of environmental change, policy support, the creation of environmental indicators and reporting. CLC datasets provide important datasets supporting the implementation of key priority areas of the Environment Action Programmes of the European Union as protecting ecosystems, halting the loss of biological diversity, tracking the impacts of climate change, assessing development in agriculture and implementing the EU Water Framework Directive, among others.
