Aerial photos (especially orthophotos) have been used in town and spatial planning for many years. Since the appearance of small unmanned aircrafts, this technology can be used in a more target-oriented way, in smaller areas and with the possibility of obtaining images of higher resolutions at less cost. Measurements, shots of the situation and visual analyses have become more quickly and cost-effectively available. The shots which accurately depict the actual situation in the environment and the position of buildings, or detect the characteristics and phenomena searched for within a given moment effectively contribute to the easier management of space and planning interventions therein. Sharply defined aerial photos with clearly visible details of the site serve as an excellent source of data for strategic planning, whether this involves a small area or the entire town.
