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.

Orthophoto is geometrically corrected aerial image ("orthorectified") such that the scale is uniform. Absolute orientation of the image and digital terrain model data is used for the ortorectification of aerial images. The optic effects and the slope of the aerial camera and the effect of the terrain diversity are removed. In a metrical sense the orthophoto is comparable with vector maps, the map sheet division is the same as for TTN 5. All orthophotos are available in TIFF format. Regarding resolution and color spectrum different orthophotos are available: - DOF025 - color (RGB) orthophoto with ground sampling distance (GSD) 0.25 m - DOF050 - color (RGB) orthophoto with ground sampling distance (GSD) 0.50 m - DOF050IR - color near infrared (IR, R and G) orthophoto with ground sampling distance (GSD) 0.50 m.

In the Remote Sensing Database the remote sensing data, ortophoto and remote sensing technical data are being managed.
