Reitakerfi Íslands er með mismunandi reitastærðum til að mæta mismunandi þörfum notenda við upplýsingamiðlun. Mælt er með notkun reitakerfisins m.a. þegar verið er að bera gögn saman milli stofnana. Reitakerfið er byggt á Lambert Azimuthal Equal Area vörpun sem tryggir að allir reitir sé jafn stórir. En það er helsta skilyrði þess að reitakerfið sé Inspire tækt. Viðmiðun er ISN 2004 Ef reitakerfið er notað í einhverjum af ISN Lambert vörpunum er það ferhyrnt. Orðskýringar: Heildarkerfið er nefnt reitakerfi. Hvert lag í því er nefnt net. Einingar í netinu eru nefndar reitir. Heiti reitana: Hver reitur hefur nafn sem er einkvæmt og er m.a. byggt upp á stærðareiningunni. 1km 10km og 100m skrárnar ná yfir strandlínu og eyjar landsins en 100km skráin nær yfir alla efnahagslögsöguna. grid_100k grid_50k grid_25k grid_10k grid_5k grid_2_5k grid_1k grid_500m grid_250m grid_100m Frekari tækniupplýsingar er að finna hér https://inspire.ec.europa.eu/id/document/tg/gg

Vegagerðin annast rekstur landsvitakerfisins og hefur umsjón og eftirlit með uppbyggingu hafnarvita og innsiglingarmerkja. Landsvitar eru til leiðbeiningar á almennum siglingaleiðum og eru í eigu og umsjá ríkisins en hafnarvitar, sem vísa leið inn til hafnar eða eru innan hafnsögu hafnar, eru í eigu og umsjá sveitarfélaga. Landsvitakerfið samanstendur af 104 ljósvitum, 11 siglingaduflum og 16 radarsvörum sem er komið fyrir þar sem landslagi er þannig háttað að erfitt er að ná fram endurvarpi á ratsjá skipa. Hafnarvitakerfið er byggt upp af tæplega 20 ljósvitum, um 90 innsiglingarljósum á garðsendum og bryggjum, rúmlega 80 leiðarljósalínum og tæplega 50 baujum er vísa leið í innsiglingum að höfnum. Viðhald og eftirlit Vegagerðarinnar með vitum landsins skiptist í stórum dráttum í eftirlit með ljósabúnaði og viðhald á vitabyggingum.

The Start-of-Season Date (SOSD), one of the Vegetation Phenology and Productivity (VPP) parameters, is a product of the pan-European High Resolution Vegetation Phenology and Productivity (HR-VPP) component of the Copernicus Land Monitoring Service (CLMS). The Start-of-Season Date (SOSD) marks the date when the vegetation growing season starts in the time profile of the Plant Phenology Index (PPI). The start-of-season occurs, by definition, when the PPI value reaches 25% of the season amplitude during the green-up period. The Plant Phenology Index (PPI) is a physically based vegetation index, developed for improving the monitoring of the vegetation growth cycle. The PPI index values, with 5-day satellite revisit cycle, are first used in a function fitting to derive the PPI Seasonal Trajectories, which is a filtered time series with regular 10-day time step. From these Seasonal Trajectories, a suite of 13 Vegetation Phenology and Productivity (VPP) parameters are then computed and provided, for up to two seasons each year. The Start-of-Season Date is one of the 13 parameters. The full list is available in the table 3 of the Product User Manual in the below link section. A complementary quality indicator (QFLAG) provides a confidence level, that is described in table 4 of the same manual. The SOSD dataset is made available as raster files with 10 x 10m and 100 x 100m resolutions, in ETRS89-LAEA projection corresponding to the HRL grid, for those tiles that cover the EEA38 countries and the United Kingdom and for two seasons in each year from 2017 onwards. It is updated in the first quarter of each year.

This metadata refers to the 'Corine Land Cover Plus Backbone' (CLCplus Backbone), a spatially detailed, large-scale, Earth Observation-based land cover inventory which is produced by the Copernicus Land Monitoring Service (CLMS). The CLCplus Backbone vector is a land cover map that contains vector polygon geometries (minimum mapping unit: 0.5 ha; minimum mapping width: 20 m) and is based on Sentinel satellite time series and a combination of existing reference datasets for geometries containing transportation and hydrological networks. Each polygon represents aggregated landscape objects and contains their dominant land cover among the 18 basic land cover classes. See polygon class codes in the additional information section. In addition, polygons are enriched with land cover fractions from the CLCplus Backbone raster as well as aggregated attributes based on other CLMS and Copernicus products (e.g. topography). CLCplus Backbone vector is an independent product and its thematic and geometric contents differ from CLCplus Backbone raster and Corine Land Cover. The CLCplus Backbone vector is available for the 2018 reference year. You can read more about the product here: https://land.copernicus.eu/en/products/clc-backbone

The Season Maximum Value (MAXV), one of the Vegetation Phenology and Productivity (VPP) parameters, is a product of the pan-European High Resolution Vegetation Phenology and Productivity (HR-VPP) component of the Copernicus Land Monitoring Service (CLMS). The Season Maximum Value (MAXV) provides the maximum (peak) value that the Plant Phenology Index (PPI) reaches during the vegetation growing season. The Plant Phenology Index (PPI) is a physically based vegetation index, developed for improving the monitoring of the vegetation growth cycle. The PPI index values, with 5-day satellite revisit cycle, are first used in a function fitting to derive the PPI Seasonal Trajectories, which is a filtered time series with regular 10-day time step. From these Seasonal Trajectories, a suite of 13 Vegetation Phenology and Productivity (VPP) parameters are then computed and provided, for up to two seasons each year. The Season Maximum Value is one of the 13 parameters. The full list is available in the table 3 of the Product User Manual in the below link section.

The MAXV dataset is made available as raster files with 10 x 10m resolutionand 100 x 100m resolutions, in ETRS89-LAEA projection corresponding to the HRL grid, for those tiles that cover the EEA38 countries and the United Kingdom and for two seasons in each year from 2017 onwards.

The decrease rate, one of the Vegetation Phenology and Productivity (VPP) parameters, is a product of the pan-European Medium Resolution Vegetation Phenology and Productivity (MR-VPP) component of the Copernicus Land Monitoring Service (CLMS). The decrease rate at the end of the season (decrease rate) expresses the rate of change in the values of the Plant Phenology Index (PPI) at the day when the vegetation growing season ends. It is calculated as the absolute value of the ratio of the difference between the right 20 % and 80% levels and the corresponding time difference. The Plant Phenology Index (PPI) is a physically based vegetation index, developed for improving the monitoring of the vegetation growth cycle. The PPI index values, with 5-day satellite revisit cycle, are first used in a function fitting to derive the PPI Seasonal Trajectories. From these Seasonal Trajectories, a suite of 13 Vegetation Phenology and Productivity (VPP) parameters are then computed and provided, for up to two seasons each year. The decrease rate at the end of the season (decrease rate) is one of the 13 parameters. The full list is available in the Product User Manual: https://land.copernicus.eu/user-corner/technical-library/clms_mrvpp_pum_d1-0.pdf The decrease rate at the end of the season (decrease rate) time series dataset is made available as raster files with 500x 500m resolution, in ETRS89-LAEA projection corresponding to the MCD43 tiling grid, for those tiles that cover the EEA38 countries and the United Kingdom and for two seasons in each year from 2000 onwards. It is updated in the first quarter of each year. The full on-line access to open and free data for this resource will be made available in the second half of 2024.
