Riparian zones represent transitional areas occurring between land and freshwater ecosystems, characterised by distinctive hydrology, soil and biotic conditions and strongly influenced by the stream water. They provide a wide range of riparian functions (e.g. chemical filtration, flood control, bank stabilization, aquatic life and riparian wildlife support, etc.) and ecosystem services. The Riparian Zones products support the objectives of several European legal acts and policy initiatives, such as the EU Biodiversity Strategy to 2020, the Habitats and Birds Directives and the Water Framework Directive. Green Linear Elements (GLE) are ecologically significant, structural landscape elements which act as important dispersion vectors of biodiversity. GLEs comprise hedgerows and lines of trees and offer a wide range of ecosystem services: they are linked to both landscape richness and fragmentation of habitats, with a direct potential for restoration, and contribute also to hazard protection. Green linear elements form part of the Green Infrastructure and are specifically addressed in the EU Biodiversity Strategy 2020. The GLE product provides reliable and detailed geospatial information on the occurrence and spatial distribution of: Small linear vegetation features such as hedgerows, scrub and tree rows with a minimum length of 100m and a width of up to 10m; Isolated patches of trees and scrub with a size between 500 m² and 0.5 ha. Green linear elements including trees and hedgerows with 100m minimum length and 500 m² Minimum Mapping Unit (MMU)

This data includes all defined hiking trails within Vatnajökull National Park, and selected trails near the park. The trails are drawn from hiking maps that the park has published since it was founded in 2008. The maps have been updated regularly since, last update was in 2019, (Snæfell area and a large part of the western region). These hiking maps can be viewed by selecting “Hiking map, click on frame” in the Vatnajökull National Park Mapview, (see link below).

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.

The Urban Atlas provides pan-European comparable land use and land cover data for Functional Urban Areas (FUA). The Street Tree Layer (STL) is a separate layer from the Urban Atlas 2012 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 Enterprise and Industry in the frame of the EU Copernicus programme, with the support of the European Space Agency and the European Environment Agency.

Þekjan sýnir orkuspársvæði sem koma fram í orkuspá Orkustofnunar. Það eru svæðin Suðurnes, Reykjavík, Vesturland, Vestfirðir, Norðurland, Austurland og Suðurland. Svæðin eru aðeins öðruvísi en í hefðbundinni landshlutaskiptingu þar sem sú skipting er til komin vegna uppbyggingar flutningskerfisins.

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 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 Institute of Nature Research during autumn of 2018 and the data and resulting report are made available on the NLSI websites.
