Rastergögn sem sýna árlegar mögulegar sólarstundir út frá landslagi á Íslandi yfir heilt ár, unnin úr IslandsDEM, 10 m hæðarlíkaninu  í EPSG:8088. Gögnin byggja á lukkustundarlegum útreikningum á landslagsskuggum frá 1. janúar til 31. desember 2027, með tímabeltinu Atlantic/Reykjavik og borgaralegu ljósaskiptaviðmiði sem nemur 6 gráðum undir sjóndeildarhring. Gildi pixla sýna fjölda reiknaðra tímaskrefa þar sem hver staðsetning var flokkuð sem sólarlýst; hærri gildi tákna tíðari sólarlýsingu yfir árið.

[EN]
Annual theoretical maximum cumulative sunlight raster for Iceland based on terrain and topological features, generated from the IslandsDEM 10 m DEM in EPSG:8088. The raster summarizes hourly terrain-shadow simulations from 1 January to 31 December 2027, using the Atlantic/Reykjavik timezone and a civil twilight threshold of 6 degrees below the horizon. Pixel values indicate the number of simulated time steps in which each location was classified as sunlit; higher values represent more frequent sunlight occurrence during the year. Clouds and other factors beside terrain are not taken into account.</gco:CharacterString>

Þetta rastergagnasafn sýnir uppsafnaða tíðni sólarlýsingar á landslagi á Íslandi árið 2027. Það var unnið út frá IslandsDEM 10 m hæðarlíkaninu í EPSG:8088 og byggir á klukkustundarlegum útreikningum á landslagsskuggum fyrir tímabilið 1. janúar til 31. desember 2027.

Hvert klukkustundarraster var reiknað út frá stöðu sólar fyrir staðsetningu hæðarlíkansins og tímabeltið Atlantic/Reykjavik. Tímaáætlunin nær yfir þau tímabil þegar sólarhæð var innan borgaralegrar ljósaskiptastöðu eða hærri, með ljósaskiptaviðmiði sem nemur 6 gráðum undir sjóndeildarhring. Þetta gerir gagnasafninu kleift að taka tillit til birtuskilyrða á háum breiddargráðum á Íslandi, þar á meðal mjög langra sumardaga og tímabila þar sem ljósaskipti ná yfir miðnætti.

Uppsafnaða rasterið sýnir hversu oft hver pixill var flokkaður sem sólarlýstur í öllum reiknuðum tímaskrefum. Hærri gildi tákna svæði sem voru oftar sólarlýst á tímabilinu, en lægri gildi tákna svæði sem voru oftar í landslagsskugga. Svæði merkt sem „nodata“ samsvara ógildum eða vöntuðum hæðargildum í upprunalega hæðarlíkaninu.

This raster represents cumulative terrain sunlight frequency for Iceland during the year 2027. It was generated from the IslandsDEM 10 m digital elevation model in EPSG:8088 and summarizes hourly terrain-shadow simulations for the period from 1 January 2027 to 31 December 2027.

Each hourly raster was calculated using the position of the sun for the DEM location and the Atlantic/Reykjavik timezone. The schedule includes times when the solar elevation was within civil twilight or higher, using a twilight depression threshold of 6 degrees. This allows the dataset to account for high-latitude lighting conditions in Iceland, including very long summer days and periods where twilight extends across midnight.

The cumulative raster records how often each pixel was classified as sunlit across all generated time steps. Higher values indicate locations that were sunlit more frequently during the modeled period, while lower values indicate locations that were more often in terrain shadow. Areas marked as nodata correspond to invalid or missing elevation values in the source DEM.</gco:CharacterString>
