Notagildi: Reitakerfi eru nauðsynlegt til að birta upplýsingar sem af einhverjum ástæðum er ekki hægt að birta stakar s.s. vegna persónuverndar, umfangs verkefnis eða nákvæmni þeirra upplýsinga sem fyrir liggja. 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

The End-of-Season Value (EOSV), 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 End-of-Season Value (EOSV) provides the value of the Plant Phenology Index (PPI) at the end of 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. 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 End-of-Season Value (EOSV) 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 End-of-Season Value (EOSV) 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. Until then the data will be made available 'on-demand' by filling in the form at: https://land.copernicus.eu/contact-form

This metadata refers to the Plant Phenology Index (PPI) Seasonal Trajectories, is one of the products of the pan-European High Resolution Vegetation Phenology and Productivity (HR-VPP) component of the Copernicus Land Monitoring Service (CLMS). The Plant Phenology Index (PPI) is a physically based vegetation index for improved monitoring of plant phenology, that is developed from a simplified solution to the radiative transfer equation by Jin and Eklundh (2014) and that has a linear relationship with green leaf area index. The PPI Seasonal Trajectories (ST) product is derived from a TIMESAT-based function fitting of the time series of the PPI vegetation index and thus provides a filtered time series of Plant Phenology Index (PPI), with regular 10-day time step. The PPI dataset is made available as raster files with 10 x 10m resolution 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. Each file has an associated quality indicator (QFLAG) that provides a confidence level.

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.

Vegagerðin rekur umferðarteljara víða um land sem telja ökutæki samfellt alla daga ársins og upplýsingar frá meira en helmingi þeirra berast sjálfvirkt til Vegagerðarinnar og eru þær upplýsingar aðgengilegar í þessari þjónustu. Umferðargreinar mæla fjölda ökutækja en auk þess mæla þeir t.d. hraða ökutækja. Aðrir umferðarteljarar skrá eingöngu fjölda ökutækja. Slíkir teljarar eru tengdir flestum veðurstöðvum auk nokkurra sem standa sér. Upplýsingar úr umferðargreinum og umferðarteljurum sem eru tengdir veðurstöðvum eru sóttar að jafnaði nokkrum sinnum á klukkustund, en upplýsingar frá teljurum sem ekki eru tengdir veðurstöðvum, berast Vegagerðinni sjaldnar.
