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.

Administrative Units (AU) is one of 12 themes in the European Location Project (ELF). The purpose of ELF is to create harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. The goal is to provide INSPIRE compliant data for Europe. A description of the ELF (European Location Project) is here: http://www.elfproject.eu/content/overview Encoding: INSPIRE version 4

EuroBoundaryMap is a seamless geo-database at the scale 1:100 000 covering 55 countries. It contains geometry, names and codes of administrative and statistical units continuously updated by the members of EuroGeographics, the national mapping and cadastral authorities (NMCAs) of Europe. Updated annually. Datasets in EBM: The EBM dataset was derived from the Icelandic National Database IS 50V, which is at the scale 1:50.000. The generalization has been applied in form of smooth polygon and simplify polygon that ensured the required resolution of the data for the EBM 1: 100 000 scale. The topological relations of the line and area features were ensured. Administrative Units includes: AdministrativeBoundary a line layer containing the demarcations outlining administrative units. AdministrativeUnit_1 a polygon layer containing the national administrative hierarchy, Level 1 (republic). AdministrativeUnit_2 a polygon layer containing the national administrative hierarchy, Level 2 (municipalities). Residence of Authority a point layer containing the administrative centres of all administrative levels. BasicGeometry includes: EBM_A a polygon layer containing administrative areas. Here are the basic components on which administrative units of all hierarchical levels, as well as all statistical layers, are composed. EBM_P a point layer meant for labelling purposes. Label points are located within the main area of the administrative units on lowest level. StatisticalUnits includes: LAU a polygon layer = Local Administrative Unit. NUTS_1 a polygon layer = Nomenclature of Territorial Units for Statistics (whole country) NUTS_2 a polygon layer NUTS_3 a polygon layer = Nomenclature of Territorial Units for Statistics (capital area, rural areas) Tables in EBM: CountryCodes = all countries have unique country codes (icc). EBM_CHR = country codes of those countries where the language is used in alphabetical order delimited by #. EBM_coAdministered = Relationship between administrative unit and its co-administering administrative units on the same hierarchical level. A few countries have special areas with shared administrative units. EBM_ISN = designations of administrative hierarchical levels EBM_NAM = names of administrative units EBM_NUTS = Relationship between the SHN codes of administrative units on lowest national administrative level and corresponding statistical codes.

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.
