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

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.

The European Ground Motion Service (EGMS), part of the Copernicus Land Monitoring Service, provides consistent, regular, standardised, harmonised, and reliable information on natural and anthropogenic ground motion phenomena across Copernicus Participating States and national borders, with millimetre-level accuracy. This metadata describes EGMS Calibrated, which represents the second level of the EGMS portfolio and is considered the primary product due to its broad applicability. Unlike EGMS Basic, Calibrated provides absolute measurements, referenced to a model derived from Global Navigation Satellite System (GNSS) data. This calibration enables direct comparison of ground motion measurements across adjacent areas and between different products of the same level. EGMS Calibrated is delivered as a vector map of measurement points, each colour-coded by average velocity. Data is distributed in comma-separated values (CSV) format. Each point includes a displacement time series, representing ground motion values per satellite acquisition. The product is available for both ascending and descending satellite orbits. EGMS Calibrated is delivered to users on an annual basis, following a five-year moving window update strategy. This means that after the Baseline/first update (2016-2021), the following data periods are available: 2018-2022, 2019-2023 and 2020-2024.

The Season Length (LENGTH), 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 Length is the number of days between the start and end dates of the vegetation growing season in the time profile of the Plant Phenology Index (PPI). 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 Length 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 LENGTH 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.

The European Ground Motion Service (EGMS), part of the Copernicus Land Monitoring Service, provides consistent, regular, standardised, harmonised, and reliable information on natural and anthropogenic ground motion phenomena across Copernicus Participating States and national borders, with millimetre-level accuracy. This metadata describes EGMS Ortho, the third product level in the EGMS portfolio. EGMS Ortho is derived from EGMS Calibrated through a resampling procedure onto a 100 m grid, using data from both ascending and descending satellite orbits. This process generates two distinct layers: one representing purely vertical displacements and one representing purely east-west displacements (the subject of this metadata). EGMS Ortho simplifies interpretation for non-expert users by removing the need to account for satellite viewing geometry, offering a more intuitive representation of ground motion. EGMS Ortho is visualised as a vector map of measurement points colour-coded by average velocity (vertical or east-west components) and distributed to users in comma-separated values format. Each point is associated with a time series of displacement, i.e. a plot with values of displacement per acquisition of the satellite. EGMS Ortho is delivered to users on an annual basis, following a five-year moving window update strategy. This means that after the Baseline/first update (2016-2021), the following data periods are available: 2018-2022, 2019-2023 and 2020-2024.

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.
