The pan-European Very High Resolution (VHR) Image Mosaic 2021 is a seamless mosaic of the VHR 2021 dataset. The input data consists of a mix of Pleiades, SuperView, Worldview, Kompsat-3, Kompsat-4, Geoeye, SPOT, Deimos-2, Vision-1 and TripleSat images. To enhance the appearance of the input imagery, a histogram stretch was applied, cutting off the lowest and highest 0.1 percent of the histogram values and stretching the remaining values to fit the 16-bit pixel depth. For each input image, only selected areas were used to create the mosaic, and the rest was masked out to exclude areas with clouds and their shadows. Color balance was achieved using a second-order method, which modifies all input pixels toward a set of multiple points derived from a two-dimensional polynomial parabolic surface, ensuring a seamless mosaic. For several water bodies, especially large lakes, the final result exhibited a patchy surface pattern due to presence of sun glint on the satellite images. A post-processing methodology was implemented to recalculate the digital values to produce a seamless appearance surface of some of these major lakes: Vänern and Vättern (Sweden), Oulu (Finland), Peipus (Estonia), Geneva (Switzerland/France), Constance (Switzerland/Germany/Austria), Garda and Bolsena (Italy), Skadar (Montenegro/Albania), Prespa (North Macedonia/Albania/Greece), Beysehir, Iznik and Van (Turkey). The applied methodology consisted of creating individual mosaics with the images comprising only the mentioned lakes (a mosaic per lake), calculating Normalized Difference Vegetation Index (NDVI) for shoreline extraction, and color balancing each mosaic individually with all land surfaces masked out, using only pixels belonging to the water category. This approach allowed smoothing the patchy surfaces of the above-mentioned lakes considering statistics solely from the water pixels, ensuring a more uniform appearance. To enhance the visualization of the entire dataset at larger scales (greater than 1:500.000), the mosaic displays pan-European overviews generated from the pan-European Very High Resolution 2018 Image Mosaic. The updated VHR 2021 version is visualized only at scales below 1:500.000. The mosaic primarily is used as input data in the production of various Copernicus Land Monitoring Service (CLMS) datasets and services, such as land cover maps and high-resolution layers on land cover characteristic. It can be also useful for CLMS users for visualizations and classifications on land. The input imagery for the creation of the mosaic is provided by ESA. Due to license restrictions, the VHR Image Mosaic 2021 is only available as a web map service (WMS), and not for data download.

Gagnaset (data set) ni_vg25r_3utg: Vistgerðir á Íslandi: land (Habitat types of Iceland: terrestrial). Vistgerðakortið sýnir útbreiðslu landvistgerða á Íslandi. Alls hafa verið ákvarðaðar 64 vistgerðir á landi og skiptast í 12 meginflokka (vistlendi). Innan landvistgerða eru fjórar jarðhitavistgerðir sem finnast á háhita- og lághitasvæðum landsins. Landvistgerðum er skipt upp í tvö þrep. Við skilgreiningu og flokkun vistgerða á Íslandi var tekið mið af EUNIS-flokkunarkerfinu (European Environment Agency 2012) . Í 3. útgáfu vistgerðakortsins 2024 eru eingöngu landvistgerðir endurskoðaðar. Náttúrufræðistofnun Íslands leggur með ritinu Vistgerðir á Íslandi fram tillögur að flokkun vistgerða sem á sér fyrirmynd í samræmdri og viðurkenndri flokkun vistgerða í Evrópu. Flokkunin byggir á rannsóknum víða um land með fyrirvara um að bæta mætti í þá þekkingu. Athuga skal að aðgreining landvistgerða með fjarkönnun reyndist erfið, bæði fyrir lítið grónar vistgerðir sem og vel grónar, einkum innan vistlenda. Því má búast við verulegum skekkjum þótt þær séu mismiklar eftir vistgerðum. Nánari útlistun og mat á skekkjum má finna í aðferðalýsingu og á staðreyndasíðum vistgerða í ritinu „Vistgerðir á Íslandi“. Frekari upplýsingar um flokkun og skilgreiningu vistgerða má sjá í ritinu: Jón Gunnar Ottósson, Anna Sveinsdóttir og María Harðardóttir, ritstj. 2016. Vistgerðir á Íslandi.

Gagnaset (data set) ni_vg25v_1.1utg og ni_vg25r_3utg: Vistgerðir á Íslandi (Habitat types of Iceland). Vistgerðakortið sýnir útbreiðslu vistgerða á Íslandi. Vistgerðum á Íslandi er skipt upp í land, ferskvatn og fjörur. Alls hafa verið ákvarðaðar 64 vistgerðir á landi, 17 vistgerðir fyrir ferskvatn og 24 vistgerðir fyrir fjörur. Landvistgerðir skiptast í 12 meginflokka (vistlendi). Innan landvistgerða eru fjórar jarðhitavistgerðir sem finnast á háhita- og lághitasvæðum landsins. Land- og ferskvatnsvistgerðir skiptast í tvö þrep, en fjöruvistgerðir í fimm þrep. Við skilgreiningu og flokkun vistgerða á Íslandi var tekið mið af EUNIS-flokkunarkerfinu (European Environment Agency 2012). Landupplýsingaþekjan fyrir landvistgerðir er á rastaformi (ni_vg25r_3utg), en þekjur fyrir jarðhita, ferskvatns- og fjöruvistgerðir er á vektorformi (ni_vg25v_1.1utg). Vektorþekjurnar eru flestar flákaþekjur, en fyrir ferskvatn er einnig línu- og punktaþekja. Gögn fyrir stöðuvötn (vg2 = V1) eru fjarlægð tímabundið úr niðurhalsþjónustu vegna ágreinings um grunnkort Loftmynda ehf. en þekjan er sýnileg í kortasjá. Náttúrufræðistofnun Íslands leggur með ritinu Vistgerðir á Íslandi fram tillögur að flokkun vistgerða sem á sér fyrirmynd í samræmdri og viðurkenndri flokkun vistgerða í Evrópu.

The European Environment Agency (EEA) is an agency of the European Union (EU) tasked with providing independent information on the environment. Established in 1990 and headquartered in Copenhagen, Denmark, the EEA serves as a key source of environmental data, assessments, and reports for policymakers and the public across Europe. With a focus on improving environmental decision-making and promoting sustainable development, the agency plays a vital role in monitoring, analyzing, and communicating environmental trends and challenges. At its core, the EEA aims to support the development, implementation, and evaluation of EU environmental policies. It achieves this mission through a range of activities, including data collection, analysis, and reporting. The agency collaborates with national environmental agencies in EU member states, as well as other international organizations, to gather and harmonize environmental data from across Europe. This wealth of information is then used to produce high-quality assessments and reports on various environmental topics. One of the primary functions of the EEA is to provide regular assessments of the state of Europe's environment. These assessments cover a wide range of issues, including air and water quality, biodiversity, climate change, and resource use. By compiling and analyzing data from different sources, the agency produces comprehensive reports that highlight key environmental trends, identify emerging challenges, and assess progress towards environmental objectives. These assessments are invaluable tools for policymakers, helping them to make informed decisions and prioritize actions to protect and improve the environment. In addition to assessing the state of the environment, the EEA also plays a crucial role in monitoring the effectiveness of environmental policies and measures. The agency tracks the implementation of EU environmental legislation and policies, assessing their impact on the ground. By evaluating the success or shortcomings of these policies, the EEA provides valuable feedback to policymakers, helping them to refine and strengthen environmental governance at the European level. Furthermore, the EEA acts as a hub for environmental information and knowledge exchange. The agency maintains several databases and online platforms, such as the European Environmental Data Centre (EEDC) and the European Environment Information and Observation Network (EIONET), which provide access to a wealth of environmental data, maps, and indicators. These resources are freely available to policymakers, researchers, NGOs, and the public, supporting evidence-based decision-making and fostering greater transparency and accountability in environmental governance.
