Svæða-, staðar- og farvegaskipting fyrir ofanflóð í samræmi við ofanflóðaskráningarkerfi Veðurstofu Íslands. Um er að ræða stigskiptingu (hierarchy) þar sem landinu er skipt niður í staði, hverjum stað svo niður í svæði og innan svæða eru svo afmarkaðir algengir farvegir ofanflóða.

Röð uppréttra loftmynda úr loftmyndasafni Náttúrufræðistofnunar sem unnar voru á árunum 2013 til 2018 hjá Jarðvísindastofnun HÍ, sem partur af tveimur verkefnum: 1 - Mælingar á jöklabreytingum úr sögulegum loftmyndum. Þetta verkefni var unnið af Joaquín M.C. Belart í M.Sc. og Ph.D. hjá Jarðvísindastofnun. Útvaldar loftmyndir frá 1945 til 1994 voru skannaðar hjá Landmælingum Íslands sérstaklega fyrir þetta verkefni. Vinnsla þessara loftmynda fór fram með því að nota "Ground Control Points" (GCP) sem teknir voru úr lidarmælingum á íslenskum jöklum. Úrvinnsla gagna úr Drangajökli fór fram með ERDAS hugbúnaðinum. Nánari upplýsingar um vinnsluna er að finna í Magnússon o.fl., 2016 (https://tc.copernicus.org/articles/10/159/2016/tc-10-159-2016.html). Úrvinnsla gagna frá öðrum jöklum var unnin með MicMac hugbúnaðinum, einnig með GCP teknir af lidar. Nánari upplýsingar um vinnsluna eru fáanlegar í Belart o.fl., 2019 (https://www.cambridge.org/core/journals/journal-of-glaciology/article/geodetic-mass-balance-of-eyjafjallajokull-ice-cap -for-19452014-processing-guidelines-and-relation-to-climate/9B715A9E0413A6345C2B151B1173E71D) og Belart o.fl., 2020 (https://www.frontiersin.org/articles/10.31630/feart/full.316390/feart. 2 - Mælingar á hraunmagni Heklugosanna á XX öld. Þetta verkefni var unnið af Gro B.M. Pedersen sem hluti af verkefni þar sem unnið var að umhverfiskortlagningu og vöktun Íslands með fjarkönnun "Environmental Mapping and Monitoring of Iceland by Remote Sensing" (EMMIRS, fjármagnað af Rannís) á árunum 2015-2018. Loftmyndirnar af Heklu frá 1945 til 1992 voru skannaðar af Landmælingum Íslands. Vinnsla þessara mynda var gerð með ERDAS hugbúnaðinum og nánari upplýsingar um vinnsluna er hægt að nálgast í Pedersen o.fl., 2018 (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2017GL076887) --------------------------------------------------------------------------------------------------------------- A series of orthomosaics using the archives of aerial photographs from Náttúrufræðistofnun (Loftmyndasafn) created between 2013 and 2018 at the Institute of Earth Sciences, as part of two projects: 1 - Measurements of glacier changes from historical aerial photographs. This project was conducted by Joaquín M.C. Belart during his M.Sc. and his Ph.D. at the Institute of Earth Sciences. A selection of aerial photographs from 1945 to 1994 were scanned at Náttúrufræðistofnun specifically for this project. The processing of these aerial photographs was done using Ground Control Points (GCPs) extracted from lidar surveys of Icelandic glaciers. The processing of the data from Drangajökull ice cap was done using the ERDAS software. Further details on the processing are available in Magnússon et al., 2016 (https://tc.copernicus.org/articles/10/159/2016/tc-10-159-2016.html). The processing of the data from other glaciers was done using the MicMac software, also with GCPs extracted from lidar. Further details of the processing are available in Belart et al., 2019 (https://www.cambridge.org/core/journals/journal-of-glaciology/article/geodetic-mass-balance-of-eyjafjallajokull-ice-cap-for-19452014-processing-guidelines-and-relation-to-climate/9B715A9E0413A6345C2B151B1173E71D) and Belart et al., 2020 (https://www.frontiersin.org/articles/10.3389/feart.2020.00163/full) 2 - Measurements of the lava volumes of the Hekla eruptions in the XX century. This project was conducted by Gro B.M. Pedersen as part of the Environmental Mapping and Monitoring of Iceland by Remote Sensing (EMMIRS, financed by Rannís) project between 2015-2018. The aerial photographs of Hekla from 1945 to 1992 were scanned by Náttúrufræðistofnun.

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.

Útlínur dregnar eftir uppréttum Sentinel-2 gervihnattamyndum. Uppréttar loftmyndir frá Loftmyndum ehf. voru einnig notaðar á nokkrum stöðum.

Þetta gagnasett inniheldur nákvæma skráningu á tillögum að orkuvalkostum sem lagðar hafa verið fram af Orkustofnun sem hluti af áframhaldandi áætlun um orkuþróunarverkefni. Það nær yfir fjölda af valkostum um orkunýtingu, þar á meðal nýtingu á vindorku, jarðvarma og vatnsorku. Gögnunum hefur verið vandlega safnað saman úr skýrslum og ýmsum viðbótarupplýsingum sem ýmsir þróunaraðilar hafa gefið Orkustofnun aðgang að. Þar má finna mikilvægar upplýsingar eins og framkvæmdarsvæði, áhrifasvæði sem táknað er með fjarlægðarhringjum (e. buffer rings) auk sértækra gagna eins og vintúrbínustillingar fyrir hvern vindorkuvalkost. Hver færsla í gagnasettinu á sér á sér samsvörun við orkuvalkost og þar er að finna eigindir eins og Ramma ID númer, nafn, þróunaðili, áætluð orkuframleiðsla, orkugerð, skilvirkni, link á skýrslu, dagsetningu umsóknar, uppruni vektorteikninga og núverandi staða valkostarins. Lagið sem heldur meginupplýsingarnar endurspeglar uppbyggingu töfluganga sem kynntar eru að vefsíðu Orkustofnunar, þar sem tryggð er skýr og kerfisbundin framsetning á gögnum til að auðvelda ítarlegt mat sem og opinbera umræðu. Hluti gagnanna er nú aðgengilegur sem WMS þjónusta --------------------------------------------------------------------------------------------- English version This dataset encapsulates a detailed inventory of power plant proposals submitted to Orkustofnun as part of an ongoing energy development project. It encompasses an array of power plant options including wind, geothermal, and hydro energy facilities. The data is meticulously compiled from submitted reports and supplementary data provided by developers to Orkustofnun. It features essential attributes such as the construction area, impact zones represented by buffer rings, and specific details like wind turbine configurations for wind energy proposals. Each entry in the dataset corresponds to a power plant proposal and includes attributes like Ramma ID number, name, developer, estimated power, energy type, efficiency class, URL link to the report, date of application, source of vectorization, and the current status of the proposal (e.g., under consideration, submitted/defined). The main information layer mirrors the structured table presented on the Orkustofnun website, ensuring a coherent and systematic presentation of data for thorough evaluation and public discourse. The data will be soon available as WMS service.

The high resolution forest product consists of three types of (status) products and additional change products. The status products are available for the 2012 and 2015 reference years: 1. Tree cover density providing level of tree cover density in a range from 0-100% 2. Dominant leaf type providing information on the dominant leaf type: broadleaved or coniferous 3. A Forest type product. The forest type product allows to get as close as possible to the FAO forest definition. In its original (20m) resolution it consists of two products: 1) a dominant leaf type product that has a MMU of 0.5 ha, as well as a 30% tree cover density threshold applied, and 2) a support layer that maps, based on the dominant leaf type product, trees under agricultural use and in urban context (derived from CLC and high resolution imperviousness 2009 data). For the final 100m product trees under agricultural use and urban context from the support layer are removed. The high resolution forest change products comprise a simple tree cover density change product for 2012-2015 (% increase or decrease of real tree cover density changes). A verification of the Tree Cover Density 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.

Slope aspect map of Iceland. This tool calculates slope aspect (i.e. slope orientation in degrees clockwise from north) for each grid cell in an input digital elevation model (DEM). “Aspect values indicate the directions the physical slopes face.” The values of each cell in the output raster indicate the compass direction the surface faces at that location. It is measured clockwise in degrees from 0 (due north) to 360 (again due north), coming full circle. Flat areas having no downslope direction are given a value of -1.
