Cyclic Aerial Survey of Slovenia

Product of aerial survey (from airplane, helicopter) are aerial images as well as external orientation elements, that are used as final product or as an input parameter for further image processing. In the cyclical aerial survey of Slovenia professional (recently digital, large format) aerial cameras are used. These cameras use simultaneous surveying of aerial photos in several channels (panchromatic, red, green, blue, near infrared). Usuall ground sampling distance (GSD) is 0.25 m.

Statement: The cyclic aerial survey period (cycle) of CAS is 2-4 years. CAS has been systematically performed since 1975 in various surveying scales (classic cameras) and with various ground sampling distances (GSD) for the acquisition with digital aerial cameras. The elements of the external orientation of the individual aerial image is given in the new coordinate system D96 in the form of coordinates of projection center of the aerial image (y, x, H) and three rotations parameters (omega, fi, kapa). Position accuracy of the aerial image is +/- 0.20 m in the projection plane and 0.25 m in height.
