The inhabited places were chosen according to their dispersion over the territory, their population, their tourist attendance and their location at the ends of numbered roads. The point is located, as the case may be, at the center of economic and commercial activity, at a road intersection, near an important physical landmark such as a church or city hall, or at the center of gravity of a concentration of homes. Names of uninhabited places are included as geographical reference points.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

[IS] Náttúrufræðistofnun heldur utan um kontrólpunkta sem er settir niður til að staðsetja loftmyndir. Í flestum tilfellum er um ræða hvíta ferningar sem eru 60x60 sm, en á jöklum eru þeir bleikir. Þar sem ekki er hægt að setja niður kontólpunkta í formi ferninga er miðað við aðra fasta punkta í landslaginu.
