The use of unmanned aerial vehicles in a number of fields of human activity represents the second wave of interest in the development and application of automated flying remotely controlled machines to collect aerial data. The former Czechoslovakia was one of the world's leading countries in the 1960s-1990s in terms of an unprecedented boom of development and applications of flying machines for imaging the Earth's surface. The reasons for their use were the same as today. Since the mid-1960s, radio-controlled (RC) models of aircraft carrying various types of photographic cameras have been developed. In spite of many administrative constraints, kite helicopters, fixed-wing aircrafts, and rogallo-wing aircrafts gradually began to be used in research. The photographic cameras for 1, 2, 4, and 6 bands carried by RC-aircraft models were developed in cooperation with leading Czech companies. These cameras used colour and black-and-white films, positive and negative films, and panchromatic, spectrozonal, and multispectral films. The general methodology and the RC-aircraft model application rules were both developed. The dominant processing method was the visual image interpretation, with and without the assistance of instruments. Optical and digital image mixers were used in Czechoslovakia, so it was possible to use natural and unnatural colour composites to highlight the studied phenomenon. A number of examples of the techniques and the scientific applications are presented in the article.
