The various types of electron-optical supervisory control systems (SCS) have been used in Armed Forces of many advanced countries. The mission of these SCS is to supervise day and night enemy troops, technics and weapon systems, frontier intruders with high precision a great and middle distance. The SCS optimal deployment in mountainous terrain makes possibility to use rationally SCS number, because SCS has very much costs. Using the rationally SCS number we can reduce a necessity of the specialist number. Also, it accelerates comander's correct decision making. The optimal deployment of SCS on a terrain is one of important task of military reconnaissance. The specific character of such task is that the necessary for continuing surveillance and control military objects can be located in specific zones of terrain (for examples, in canyons, along of river etc.). Accessible places of SCS set are situated on some distance from these zones. The number of SCS is limited; therefore, it is impossible to distribute theirs on the all set points. It is necessary to select such SCS set points that the zone observation range would be the largest. In present paper the mathematical model of the rationally deployment of technical observing systems in mountainous terrain has been developed and offered. The determination method of visibility level between selected terrain points has been developed. The assesment criterion of rationally deployment and the algorithm of fast solution have been offered.

The various types of electron-optical supervisory systems (SCS) have been used in the border stations of border zones in the Armed Forces of many countries. The mission of these SCS is to supervise the possible activities of smugglers, the illegal movement of enemy troops, the technics and weapon systems, the frontier intruders. In the paper, there has been offered a method which, on the basis of the developed mathematical model and Geography Information System technology, allows modeling of observation in mountain terrain depending on the number and location of SCS. The developed software module allows: 1) to generate the investigated terrain based on Digital Terrain Elevation Data file, 2) to input the possible observation points and the controlled zone via an interface, 3) to simulate and visualize the observed areas for both single and group observation devices located in the possible observation points. The developed method had been applied to one of the selected terrains of the Azerbaijan Republic and demonstrated efficiency of the offered method. Based on the developed model and GIS technology the visual modeling in mountain terrain depending on a number and a location of the SCS has been carried out.
