METHOD FOR RECEIVING AND ACTUALIZATION OF DIGITAL CARTOGRAPHIC MATERIAL AND DEVICE FOR REALIZATION OF SAID METHOD

摘要

FIELD: digital cartography and symbolic circuits.;SUBSTANCE: method includes forming matrix for transforming image or objects coordinates distortion matrix on certain digital plans and symbolic circuits relatively to true geographic coordinates received for tracked objects via navigation devices of users, by combining plans or symbolic circuits with precise terrain chart. Distortion matrix is included in contour of displaying objects on plans and circuits, on basis of true geographic coordinates of tracked objects, sent in by users. A layer of plan or circuit of terrain transformed according to matrix is formed, on which tracked objects are marked by certain graphic symbols. Data, received on circuit, for example, route and movement speed of each tracked object, is relayed to certain users with visualization of symbolic circuit on indication device of each user. Device for realization of method has digital terrain chart, received information processing device, information indication device, n components of subscribers complex. Each component has device for determining coordinates on terrain connected by its input to output of controlling device, directly or through encoder/decoder. Outputs of control device are connected to inputs of information indication device and to device for connecting to radio channel. Device for connecting each subscriber component to radio channel is connected by its input to output of control device and is connected to group device for connecting to radio channel belonging to base portion of device for receiving digital cartographic material. Another input and output of group device for connecting to radio channel are connected directly to output and input of coordinates transforming and controlling device or respectively to output and input of second encoder/decoder, connected by other its input and output respectively to output and input of device for coordinates transformation and control. Another input of coordinates transformation and control device is connected to output of distortion matrix storage device. Next input and output of coordinates transformation and control device are connected respectively to output and input of block, containing digital terrain charts and to output and input of block, containing symbolic circuits or plans of same terrain.;EFFECT: higher speed of operation, higher effectiveness.;2 cl, 1 dwg
