    The European Urban Atlas provides reliable, inter-comparable, high-resolution land use and land cover data for 800 Functional Urban Area (FUA) for the 2012 reference year in EEA39 countries. The spatial data can be downloaded together with a map for each FUA covered and a report with the metadata for the respective area. Additional information (product description, mapping guidance and class description) can be found here: https://land.copernicus.eu/user-corner/technical-library/urban-atlas-2012-mapping-guide-new 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.

    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)

    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.

    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 will 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. Land Cover/Land Use (LC/LU) classification is tailored to the needs of biodiversity monitoring in a tailored buffer zone along large and medium-sized European rivers (with Strahler levels 3-8 derived from EU-Hydro). LC/LU is extracted from VHR satellite data and other available data in a buffer zone of selected rivers. The classes follow the pre-defined nomenclature on the basis of MAES typology of ecosystems (Level 1 to Level 4) and Corine Land Cover, providing 80 distinct thematic classes with a Minimum Mapping Unit (MMU) of 0.5 ha and a Minimum Mapping Width (MMW) of 10 m. The production of the Riparian Zones products was coordinated by the European Environment Agency in the frame of the EU Copernicus programme.

    Hæðarlínur og landlíkan unnin upp úr loftmyndum af Markarfljóti. Vektorgögn: Gögnin voru unnin af Samsýn ehf og voru unnin upp úr myndkortinu af sama svæði. Geymd í ArcGIS File Geodatabase. Gögnin eru flokkuð skv. staðli IST120 frá árinu 2007. Hnitakerfi er ISN93, lambert kortvörpun. 3 Fitjuklasar afhentir: - Hæðarlínur með 1 m. millibili - Hornpunktar þríhyrningalíkans af landi - Brotlínur landlíkans (þrívíðar) Útgáfudagsetningin 09.12.2010 er tekin af lýsingunni sem fylgdi gögnunum til LMÍ. LMÍ gerði nytjaleyfissamningur um gögn Samsýnar ehf úr loftmyndum af Eyjafjallajökli og Markarfljóti, í umboði nokkurra stofnanna: - Vegagerðin - Landgræðslan - Veðurstofa Íslands - Umhverfisstofnun - Náttúrufræðistofnun. Gögnin voru unnin úr loftmyndum, annars vegar úr háflugi yfir Eyjafjallajökli og hluta Mýrdalsjökuls og hins vegar úr lágflugi yfir Markarfljóti. Ástæðan fyrir því að farið var út í þetta verkefni var eldgosið sem átti sér stað sama ár (2010)í Fimmvörðuhálsi. Tilgangurinn var að greina breytingarnar sem eldgosið orsakaði. Verkefnið var tvískipt: Annars vegar var um að ræða þetta hæðarlíkan og hins vegar myndkort. Sjá lýsigögnin hér í Landupplýsingagáttinni undir "Markarfljót - myndkort".

    Póst og fjarskiptastofnun (PFS) hefur framkvæmt mælingar á fjarskiptasambandi á helstu vegum í vegakerfinu á Íslandi. Mælingar voru gerðar á GSM, UMTS (3G), LTE (4G) og TETRA á vegum Símans, Nova, Vodafone og Neyðarlínunnar. Verkefnið var unnið að ósk Fjarskiptasjóðs og fór þannig fram að starfsmenn PFS óku eftir þeim vegum sem mældir voru með tilheyrandi mælitæki. Mælingar hafa verið gerðar frá 2012 en flestar mælingarnar voru gerðar frá haustinu 2015 til haustsins 2016 en þar sem hröð uppbygging á fjarskiptakerfinu er sífellt í gangi geta niðurstöður sýnt lakari dreifingu en raun er orðin síðan mælingarnar voru gerðar. Þá er einnig rétt að hafa í huga að loftnet símtækja geta verið mismunandi að gæðum og því ekki alltaf víst að ferðalangar um vegi landsins fái sömu upplifun varðandi styrk merkja og kortin gefa til kynna.

    Tölur varðandi fastanettengingar fasteigna á landinu öllu skipt eftir þéttbýli og dreifbýli. Gögnin sýna ekki hvaða tengingu fasteignir eru að nýta heldur hverjar þeirra tengst í gegnum ADSL, VDSL og ljósleiðara. Gögnin sýna einnig hver á þá strengi sem hægt er að tengjast í gegn um. Þéttbýli er skilgreint sem svæði þar sem fasteignir (lögheimili og vinnustaðir einungis) eru með minnst 200 metra á milli sín og inniheldur minnst 50 slíkar fasteignir. Mögulegur hámarkshraði tenginga er áætlaður fyrir fasteignir.
