Aerial photography
Aerial photography is carried out by taking specialist oblique aerial photographs from small aircraft. The majority of archaeological sites become visible due to colour markings (on the ground) or vegetation markings (different growth and ripening of crops) and in specific conditions (drought, floods, low light, certain levels of plant growth). The extensive archive of cyclic photographs of Slovenian territory serves to enable the recognition of new archaeological sites, monitor their condition, and monitor any changes that occur throughout the territory.
