This raster dataset is a visibility analysis of several wind turbine projects across Iceland which are a part of the fifth phase of the master plan (Rammaáætlun http://www.ramma.is/). The area analysed is a 45 km buffer zone around each wind turbine project. The cutout areas in the 45 km buffer have no visibility due to visual obstruction. The red colour represents high visibility, fading into yellow, with the green colour representing low visibility of the wind turbines. Zones of theoretical visibility have been classified as near (0-2km), intermediate (2-15km) and remote zone (>15km) which are represented in the colour grading. It should be considered that atmospheric conditions, lighting, shading and more affect visibility and detectability. The perception of the wind projects in the green zone will be more fading in the landscape without direct detection, while in the red coloured zone the wind turbine is a prominent element in the landscape. For further information consider reading the respective chapter in the project report or check out further tools like the Ramma 3D map. As a digital elevation model the 10x10 m resolution ÍslandsDEM is used which sets the dataset pixel resolution to 10x10 m. An average viewer height of 1.75 m is assumed, while the wind turbine heights vary between 150 m and 200 m depending on project sites. The maximal height of the wind turbine is considered, meaning to the upper blade tip. See more information in the table on the side. The curvature of the earth is considered in the simulation and a default atmospheric refraction of 0.13 is assumed.

The Corine Land Cover datasets CLC2000, CLC2006and CLC change 2000-2006areproduced within the frame of the GMES land monitoringproject.Corine Land Cover (CLC) provides consistent information on land cover and land cover changes across Europe. This inventory was initiated in 1985 (reference year 1990) and established a time series of land cover information with updates in 2000 and 2006.CLC products are based on photointerpretation of satellite images by national teams of participating countries - the EEA member and cooperating countries – following a standard methodology and nomenclature with the following base parameters: 44 classes in the hierarchical three level Corine nomenclature; minimum mapping unit (MMU) for status layers is 25 hectares; minimum width of linear elements is 100 metres; minimum mapping unit (MMU) for Land Cover Changes (LCC) for the change layers is 5 hectares. The resulting national land cover inventories are further integrated into a seamless land cover map of Europe.Land cover and land use (LCLU) information is important not only for land change research, but also more broadly for the monitoring of environmental change, policy support, the creation of environmental indicators and reporting. CLC datasets provide important datasets supporting the implementation of key priority areas of the Environment Action Programmes of the European Union as protecting ecosystems, halting the loss of biological diversity, tracking the impacts of climate change, assessing developments in agriculture and implementing the EU Water Framework Directive, among others.More about the Corine Land Cover (CLC) and Copernicus land monitoring data in general can be found at http://land.copernicus.eu/.

Þann 16. mars 2011 gáfu Náttúrufræðistofnun út í fyrsta sinn sameiginlegt hæðarkerfi fyrir Ísland. Kerfið er kallað Landshæðarkerfi Íslands og er viðmiðunin ISH2004. Tilkoma sameiginlegs hæðarkerfis markaði stór tímamót í sögu landmælinga á Íslandi. Á sama hátt og viðmiðunin ISN93 skapaði grundvöll fyrir alla til að vinna í sama hnitakerfi mun ISH2004 skapa grundvöll fyrir alla til að vinna í sama hæðarkerfi. Eitt samræmt hæðarkerfi er mikilvægt fyrir ýmsar framkvæmdir s.s. vegagerð og jarðgangnagerð og á ýmsum sviðum umhverfisvöktunar, skipulags og áætlanagerðar. Auk þess munu gögnin nýtast við rannsóknir á jarðskorpuhreyfingum eða breytingum á yfirborði sjávar. Mælingar á Landshæðarkerfinu eru standa ennþá yfir og frá fyrstu útgáfu þess árið 2011 hafa bæst við eftirfarandi línur hallamælilínur. • Flókalundur-Bolungavík • Reykjavík-Keflavík • Endurmæling á Suðurlandi vegna jarðskjálftans 2008 • Hellisheiði • Reykjanesbraut-Grindavík • Þjóðvegur 1-Akranes • Kjölur Niðurstöður nýrra mælinga verður bætt inn í þetta gagnasett um leið og þær liggja fyrir.

Ýmsar tölulegar upplýsingar úr manntali Hagstofunnar frá 2011, settar fram á smásvæðaskiptingu Hagstofunnar. Vinsamlega hafið samband við Hagstofuna vegna nánari upplýsinga.

Línurnar sýna friðunarsvæði, þar sem eldi laxfiska (fam. salmonidae) í sjókvíum er óheimilt skv. auglýsingu nr. 460/2004.
