Orthophoto Telemark 2004

Orthophoto has the same geometric properties as a map and can be linked to a reference system. Orthophotos are divided into different orthophoto standards suitable for different purposes. Photo by Ortho: Round-trip photography covering the whole country. Ground resolution of these varies between 0.50, 0.40 or 0.25 m. From 2012, ground resolution applies 0.25 m for orthophoto from orbital photography. Accuracy ± 2 m for Ortophoto 50 (depends on the quality of the used height model) Orthophoto has the same geometric properties as a map and can be linked to a reference system.
