In article the topical issues connected with processing of digital aerial photographs in system of air reconnaissance are considered. The received digital aerial photographs, by means of onboard pilotless complexes in the course of conducting air reconnaissance, differ in high degree of a saturation in fine details, having significant amounts of information reaching about 100 Mbit. Therefore, there are questions, connected not only with timeliness of transfer of aerial photographs to the center of information processing, but also need of ensuring the required level of preservation of key signs for further decryption of aerial photographs. It is offered to carry out previously processing of aerial photographs onboard that will lead to decrease in information intensity on condition of saving information, semantic significant for decryption. The method of coding of blocks of an aerial photograph taking into account degree of a semantic saturation of each block is developed for onboard pilotless complexes of air reconnaissance. Based on formation of the sequence of significant two-element vectors for the structurized transformants. Use of a method will allow to reduce the volume of the processed and transmitted data that will bring to increase in integrity of information in system of air reconnaissance.
