Topical issues of remote assessment of the forest pathological condition of forests are substantiated, in particular, it is emphasized that today this type of decryption is the least developed link in the section of forest decoding. This is due to the unstable manifestation and diagnosis on the materials of aeronautical surveys of signs of deciphering trees and plantations of varying degrees of attenuation and drying. Forest decoding of aerospace imagery materials today is the process of recognizing aerial objects depicted on aerospace images and establishing their quantitative and qualitative characteristics. The subject of the work is the fundamental aspects of forest decoding, which in turn can be visual (eye, analytical), measuring, automatic (machine), as well as complex-analytical or automated (interactive). For all types of visual decoding of the investigated forest objects, as a rule, characterize, on the basis of decryption signs, its image on an aerial photo or space picture (on paper or computer screen) with the naked eye or by means of magnifying or stereoscopic devices. Therefore, methodological correctness and clarity in deciphering satellite images of forest arrays obtained through satellite communication channels is quite important today, using satellite and internet technologies. The purpose of the study is to study and systematize materials for deciphering geoinformation images of forests that were obtained by satellite sounding of forests in Ukraine as a whole, and in the Zhytomyr region in particular. The main methods of carrying out the works are the computational-analytical on the collection and processing of the results of space images of satellite sounding of forests located in the territory of Zhytomyr region. In addition, it should be noted that remote satellite sensing of forests enables, with the correct methodological decryption of space images, not only to monitor, but also to make a prediction of the spread of harmful organisms in the forests of Zhytomyr region.

According to the results of the work, it is established that the information from the aerospace image is read and analyzed by means of visual and logical devices of the decoder. Therefore, analytical decryption, and especially with the use of certified computer software, allows not only a high-quality reading of space images of forest covered areas of Zhytomyr region, but also to make a long-term forecast for the spread and spread of pests and diseases of the forest in a certain area. The scope of the research results are forestry enterprises of the Zhytomyr Regional Forestry and Hunting Directorate, Ecological and Naturalistic Centers, State environmental inspections including in the Zhytomyr region for space monitoring of the state of forest ecosystems, as well as conducting forestry and nature activities forest of Zhytomyr Polesie. The conclusions of the research are that in Zhytomyr Polissya, when measuring decryption, all or some of the parameters and characteristics of the decrypted objects are measured in pictures using mechanical, opto-mechanical, opto-electronic and other measuring instruments, devices, devices and systems. In analytical-measuring decryption, a visual-logical analysis of the image is combined with the measurement of different parameters of the decrypted objects. Automatic decryption is based on the recognition of spectral and morphometric characteristics of decrypted objects, their quantitative and qualitative indicators. In this case, the decryption process is performed using image processing equipment. The role of the individual is to create a system, define a specific task and process the captured information with the help of appropriate programs, and to maintain the normal functioning of the system. Automated (interactive) decryption combines elements of analytic-measuring, performed by the decryptor-operator on the image on the computer screen, with automatic decryption. In this case, the collected information is analyzed and processed using technical means of image processing with the active participation of the decoder. Depending on the location, the decryption can be field, camera (laboratory), aerial or combined. Field decryption is carried out directly on the ground by comparing the image on aerial or space images with nature. The field decryption method is the simplest and most accurate, but it takes a lot of time and labor. Cameral decryption is carried out in the laboratory, while reducing the cost of engineering staff and workers, there is an acceleration of work and a significant reduction in their cost. Camera decryption is always done with the help of additional cartographic, regulatory and other stock materials. Aero-visual decryption is performed by comparing images of identified objects in aerial or space imagery with terrain when flying on planes or helicopters. The analysis of the informative content of the shooting materials shows that their practical application is possible, as a rule, on the basis of a rational combination of methods of terrestrial and remote observations.Keywords: remote evaluation, forest pathological condition, aerial photos, aerial photos, remote satellite sounding of forests, signs of decryption, space monitoring of forests in Zhytomyr region.
