The Urban Atlas provides pan-European comparable land use and land cover data for Functional Urban Areas (FUA) across EEA38 countries (EU, EFTA, Western Balkan countries as well as Türkiye) and United Kingdom. The Street Tree Layer (STL) is a separate layer from the Urban Atlas 2018 LU/LC layer produced within the level 1 urban mask for each FUA. It includes contiguous rows or a patches of trees covering 500 m² or more and with a minimum width of 10 meter over 'Artificial surfaces' (nomenclature class 1) inside FUA (i.e. rows of trees along the road network outside urban areas or forest adjacent to urban areas should not be included). Urban Atlas is a joint initiative of the European Commission Directorate-General for Regional and Urban Policy and the Directorate-General for Defence Industry and Space in the frame of the EU Copernicus programme, with the support of the European Space Agency and the European Environment Agency.

Smásvæði Ísland er dreifbýlt land, en þéttbýlt á höfuðborgarsvæðinu. Hefðbundin skipting landsins í landsvæði og sveitarfélög býður ekki upp á samanburðarhæf svæði hvað varðar hagskýrslugerð. Hagstofan hefur því aukið við flokkunarkerfi fyrir hagskýrslusvæði með því að bæta við smásvæðum sem hafa að meðaltali 1.700 til 1.800 íbúa. Smásvæðin mynda fimmta stigið í flokkunarkerfi, með því að hluta talningarsvæðin frekar niður. Alls eru smásvæðin 206 með rúmlega 1.700 manns meðalíbúafjölda, og íbúafjöldanum haldið á bilinu 900 til 3.500 manns, en sem næst meðaltalinu. Þrepin í flokkunarkerfinu eru þessi. 1 - Ísland allt 2 - Tvö hagskýrslusvæði (NUTS3) – höfuðborgarsvæði og landsbyggð 3 - Fjórir landshlutar – tveir á höfuðborgarsvæðinu og tveir á landsbyggðinni 4 - Alls 42 talningarsvæði – 13 í Reykjavík, 11 í Nágrenni Reykjavíkur, 9 á Suðursvæði og 9 á Norðursvæði. 5 - Alls 206 smásvæði – hverju talningarsvæði skipt upp í 2 til 11 smásvæði. Með smásvæðaskiptingunni verður mögulegt að birta ítarlegar hagskýrslur fyrir smærri svæði en áður án þess að þurfa að sleppa úr svæðum eða eyða tölum vegna fámennis. Smásvæðin eru skilgreind vegna þarfa manntalsins 2021, en einnig hefur verið gerð sérstök útgáfa fyrir manntalið 2011, með 183 svæðum sem fylgja að mestu sömu mörkum. Smásvæðaflokkunin var unnin í samstarfi við Byggðastofnun, með fjárhagslegum stuðningi frá Evrópusambandinu. Þá naut Hagstofan aðstoðar Landmælinga Íslands ásamt afnotum af gögnum frá Landmælingum og Mílu ehf. -------------------------------------------------------------------------------------------------------------------------------------- Minor Statistical Output Areas (MSOA) Due to the sparsely populated country and huge differences in the population sizes of the administrative units, Statistics Iceland has added a new small area level to the hierarchical regional classification in preparation for the 2021 Census. The new level is labeled as Minor Statistical Output Areas (MSOA). There are in total 206 MSOA defined, with an average population in the range 1,700 to 1,800 persons and no area having less population than 900 persons, and no area exceeding 3,500. There are 5 steps in the Regional classification: 1 - Iceland 2 - Two NUTS3 Statistical regions 3 - Four Statistical Regions – 2 in the capital region and 2 in the rural areas 4 - Forty-two (42) Statistical Output Areas (SOA) – 42 areas, 13 in Reykjavik, 11 in the Reykjavik surrounding areas, 9 in the South Region, and 9 in the North region 5 - Two hundred and six (206) Minor Statistical Output Areas (MSOA) –each SOA partitioned further into 2 to 11 MSOA. With the help of the Minor Statistical Output Areas Statistics Iceland is able to publish detailed statistics for smaller areas than previously possible without skipping areas or deleting data due to disclosure concerns. While the MSOA are defined in preparation for the 2021 Census of the Population and Housing, a special version has been developed for classifying data in the 2011 Census, with 183 MSOA, which are but for 23 areas identical to the 2021 version. The MSOA were developed with financial aid from the European Commission, in cooperation with the Icelandic Regional Development Institution and the assistance of the National Land Survey of Iceland and Míla ehf.

Over 2,500 marine animal species have been found in Iceland’s exclusive economic zone, but there are certainly many more. Species diversity within some animal phyla in Icelandic waters is still poorly understood. Presumably, however, species fall under different phyla in similar proportions as elsewhere in the world. Information on marine animal species in Icelandic waters can be found on animal fact sheets on the NSII website.see: https://www.natt.is/is/leit-i-biota?kingdom_group.keyword=%2522D%25C3%25BDr%20%2528Animalia%2529%2522

Kjördæmi eru afmörkuð landsvæði sem mynda einn af grunnþáttum kosningakerfisins. Framboðslistar eru lagðir fram fyrir hvert og eitt kjördæmi þannig að kjósendur í sama kjördæminu geta valið á milli sömu framboðslistanna og kjörnir fulltrúar hljóta þar umboð sitt til þingsetu. Kjördæmaskipulagið og fjöldi kjósenda í hverju þeirra liggur til grundvallar þegar þingsætum er úthlutað eftir þingkosningar. Þar sem kjördæmaskipulagið er ráðandi fyrir vægi atkvæða kjósenda hefur það mikil áhrif á það hvaða frambjóðendur fá sæti á þingi að loknum kosningum. Kjördæmaskipulagið er því meðal þess sem oft hefur orðið að deiluefni. Þegar gerðar voru á því verulegar breytingar kostuðu þær jafnan pólitísk átök og allar hafa þær þýtt málamiðlanir milli ólíkra sjónarmiða.

The Coastal Zones LC/LU Change (CZC) 2012-2018 is providing the Land Cover / Land Use (LC/ LU) change for areas along the coastline of the EEA38 countries and the United Kingdom, between the reference years 2012 and 2018. The Coastal Zones product monitors landscape dynamics in European coastal territory to an inland depth of 10 km with a total area of approximately 730,000 km², with all the relevant areas (estuaries, coastal lowlands, nature reserves). The production of the coastal zone layers was coordinated by the European Environment Agency (EEA) in the frame of the EU Copernicus programme, as part of the Copernicus Land Monitoring Service (CLMS) Local Component. The Coastal Zones Change product covers a buffer zone of coastline derived from EU-Hydro v1.1. The Land Cover/Land Use (LC/LU) Change layer is extracted from Very High Resolution (VHR) satellite data and other available data. The reference years for the change are 2012 and 2018. The class definitions follow the pre-defined nomenclature on the basis of Mapping and Assessment of Ecosystems and their Services (MAES) typology of ecosystems (Level 1 to Level 4) and CORINE Land Cover adapted to the specific characteristics of coastal zones. The classification provides 71 distinct thematic classes with a Minimum Mapping Unit (MMU) of 0.5 ha and a Minimum Mapping Width (MMW) of 10 m. The status product is available for the 2012 and 2018 reference years. This CZC dataset is distributed in vector format, in a single OGC GeoPackage file covering the area of interest.

[IS] Staðsetningar borkjarna og borsvarfs í Borkjarnasafni Náttúrufræðistofununnar. Náttúrufræðistofnun hefur það hlutverk að varðveita borkjarna sem falla til við jarðboranir víða um land við framkvæmdir eða í rannsóknaskyni. Borkjarnar og borsvarf veita innsýn í þann hluta berggrunnsins sem ekki er sýnilegur á yfirborði jarðar og eru nauðsynleg gögn við jarðvísindalegar rannsóknir, hvort sem um ræðir grunnrannsóknir eða hagnýtar rannsóknir við undirbúning mannvirkjagerðar eða nýtingar náttúruauðlinda. Safnið geymdi í lok árs 2024 um 100 kílómetra af borkjörnum auk borsvarfs úr borholum sem samtals eru yfir 470 km að lengd. Telur gagnagrunnur safnsins nú tæplega 11 þúsund kassa af borkjörnum úr um 1.800 borholum, sem og um 5.000 bakka af borsvarfi úr um 2.300 borholum. Í safninu er einnig talsverður fjöldi sýna sem tekin hafa verið úr borkjörnum og varðveitt aðskilin frá meginhluta kjarnanna.

The Drill Core Library (DCL) of the Natural Science Institute of Iceland comprises over 100 km of drill cores and large quantities of drill cuttings from scientific and applied research drilling throughout Iceland. Drill cores and drill cuttings enable us to examine those portions of the bedrock that are not exposed at the surface. They are essential sources of data for geoscientific research, both fundamental research and applied studies for construction or utilization of natural resources. The DCL includes cores from research drilling in Surtsey in 1979 and 2017, which shed remarkable light on the inner evolution of the island after the eruption, and a core from a 2 km-deep research borehole in drilled in Reyðarfjörður in 1978. The collection also includes a vast array of cores drilled in connection with the construction of tunnels and hydroelectric power plants and other research on energy resources.
