Orthophoto Orkdal 2002 buildings

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 10: Normally covers urban areas and development areas where there is a need for good location accuracy and high resolution. The ground solution is usually 0.04 – 0.15 m. Accuracy ± 0.35 m. Orthophoto has the same geometric properties as a map and can be linked to a reference system.
