Orthophoto Etne 1993

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. Orthofoto N50 represents older images and is produced specifically for the Norwegian Mapping Authority. Orto N50 has ground resolution 1.0 m. Accuracy ± 10 m.
