      <gmd:abstract>
        <gco:CharacterString>L’ensemble des données prises en compte représente un total de 609481 points lumineux référencés et géolocalisés dans la zone d’étude « stricte » (région Bretagne seule).

Les caractéristiques techniques des points lumineux conditionnent très fortement leur contribution à la
pollution lumineuse. Quatre d’entre elles jouent un rôle particulièrement important :
– Le type de lampe : une nomenclature de 13 types a été définie par DarkSkyLab.
– La puissance (exprimée en Watt)
– La température de couleur (exprimée en Kelvin) : les valeurs les moins élevées correspondent à une
lumière chaude (orange) tandis que les valeurs les plus élevée correspondent à une lumière froide
(blanc-bleue).
– L’ULR (exprimée en %) : il s’agit du pourcentage du flux lumineux qui s’échappe au-dessus de
l’horizontale.

Les données d’éclairage public mises à disposition de DarkSkyLab ont été rassemblées au sein d’une base de données unique conforme au modèle de données standardisé qui a été créé à l’initiative de la FNCCR (Fédération nationale des collectivités concédantes et régies) lors du projet national France Data Réseau, auquel a participé DarkSkyLab.</gco:CharacterString>
