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.

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

An orthophoto is an aerial photograph that has been transformed from a central to an orthogonal projection by taking into account terrain relief data and the absolute orientation of the aerial photographs. In this process, the effects of the camera optics, camera tilt, and terrain undulation are removed. Orthophotos are metrically comparable to line maps, and their sheet division corresponds to that of TTN5. All orthophotos are available in TIFF format. Different orthophotos are produced according to spatial resolution and colour spectrum: DOF025 – colour (RGB) orthophoto with a ground sampling distance (GSD) of 0.25 m DOF050 – colour (RGB) orthophoto with a ground sampling distance (GSD) of 0.50 m DOF050IR – colour near-infrared orthophoto (IR, R and G) with a ground sampling distance (GSD) of 0.50 m
