The aim of the thesis is to develop models, methods and tools for forming dynamic scripting of navigation GIS pealnogo time to improve the adequacy of representation and perception of the surrounding environment, which includes moving objects space, air and land-based. Object of study - the formation and displacement mapping space, air and ground moving objects on thematic mapping navigation background in geographic information systems, real time. Purpose of the study - models, methods and means of forming dynamic scripting of navigation in GIS real-time systems. Research methods. To solve the tasks was used a range of methods: for modeling static and dynamic component of GIS navigation RF - System Analysis V. Glushkov, set theory, graph theory; to formalize the representation of domain knowledge - methods of discrete mathematics and mathematical modeling; to create a base map data - the methods of photogrammetry and computer graphics; for software implementation models and algorithms of dynamic scenario - methods structured, modular and object-oriented programming. The thesis unleashed relevant scientific and applied problems in the formation of dynamic scripting of navigation GIS real-time systems to improve adequacy of reflection and perception of the current situation in the area of ??objects of space, air and land-based. In solving this problem received the following major scientific and practical results: 1. First the model of interaction between application data and aerial photography technology integration that include navigation data processing unit and the correction unit scan areas, working in parallel and can create orthophotos given land areas without loss of quality and with significant savings of time, in general, allows you to build large-scale maps of any thematic content. 2. For the first time the model of the base map data, which is the essence of differentiation ties cartographic objects (concepts) to release content, graphics and spatial sets based on the unity of their conceptualization and interpretation in the electronic map as a single file (in the prototype and 5 more). 3. Improved technology for displaying characters moving objects by creating a data base with a complex character attributes for ground units, aircraft and space objects depending on their type, structure and functionality, was developed a method of displaying movements of characters moving about ' cartographic objects in a background of dynamic frequency recovery stage 50 times per second, providing a smooth display and in turn, more adequate perception of the dynamic situation of human operator. 4. The improved model of dynamic scenarios in GIS navigation RF. The essence of the improvements is a new formalization describe composite objects moving in space, air and ground spaces, and symbols using the method of transformation of moving objects in sync with the scale cartographic background that allows to adapt the dynamic scene according to the needs of the operator. 5. The proposed software forming dynamic scenarios include: - A program of formation dynamic scenario shore on the example of specific areas of the field (p. Wheat, Vasylkiv district, Kyiv region.) And the type of character can be anything, and their complexity can range from 8x8 to 32x32 dots; - Web-application to create dynamic scenario move objects three types based, using the proposed thematic map data base that allows simultaneously perform storage and processing of data from the client, regardless of the access to the Web-server. 6. Comparison of qualitative and quantitative indicators of performance offered by information technology forming dynamic scripting with known prototypes. Established that its main advantage is that they are, in addition to high performance, is the domestic product which, in turn, enables refinement and modification. The results of proponuэtsya used on farms and agricultural enterprises, transport logistics business direction, institutions cadastre, as well as conduct training and educational activities, including the National University of life and environmental sciences of Ukraine.
