    Notagildi: Reitakerfi eru nauðsynlegt til að birta upplýsingar sem af einhverjum ástæðum er ekki hægt að birta stakar s.s. vegna persónuverndar, umfangs verkefnis eða nákvæmni þeirra upplýsinga sem fyrir liggja. Reitakerfi Íslands er með mismunandi reitastærðum til að mæta mismunandi þörfum notenda við upplýsingamiðlun. Mælt er með notkun reitakerfisins m.a. þegar verið er að bera gögn saman milli stofnana. Reitakerfið er byggt á Lambert Azimuthal Equal Area vörpun sem tryggir að allir reitir sé jafn stórir. En það er helsta skilyrði þess að reitakerfið sé Inspire tækt. Nánari upplýsingar um vörpunina eru hér fyrir neðan. Heiti kerfis: ISN2004_LAEA Kortavörpun: Lambert_Azimuthal_Equal_Area Lengdargráða miðpunkts vörpunnar: W19 Breiddargráða miðpunkts vörpunnar: N65 Austurhnit miðpunkts: 1700000 Norðurhnit miðpunkts: 1300000 Eining: Meter Viðmiðun: ISN2004 Sporvala: GRS80 Orðskýringar: Heildarkerfið er nefnt reitakerfi. Hvert lag í því er nefnt net. Einingar í netinu eru nefndar reitir. Heiti reitana: Hver reitur hefur nafn sem er einkvæmt og er m.a. byggt upp á stærðareiningunni. 1km og 10km skrárnar ná yfir strandlínu og eyjar landsins en 100km skráin nær yfir alla efnahagslögsöguna. Grid_ISN2004_LAEA_1K Grid_ISN2004_LAEA_10K Grid_ISN2004_LAEA_100K 100m netinu er skipt upp í 4 skrár (SW, SE, NW og NE) vegna stærðar.

    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: 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.
