Performance measurements and optimization of visualization of routes traveled in the distributed dispatcher and teleinformation system for visualization of multimedia data for the Border Guard

Monitoring of country maritime border is an important task of the Border Guard. This activity can be enhanced with the use of the technology enabling gathering information from distributed sources, processing of that information and its visualization. The system presented in the paper is an advancement of the previously developed distributed map data exchange system. The added functionality allows to supplement the map data with multimedia (telephone and radio calls, video (cameras), photos, files, SMS) and presentation of current and archival situation on a multidisplay screen in the Events Visualization Post. The performance tests, and in particular the measurement of waiting times for responses, show that the biggest influence on the Center server delays is the handling of messages regarding visualization of traveled routes. Therefore, it was decided to optimize the way of visualization of traveled routes on digital maps in order to reduce the amount of overload of the Center. The main focus of this article is a description of the concept of a new method of visualization of traveled routes and a new way of retrieving data on traveled routes. In addition, the paper sets further direction for the development of the STRADAR system, such as visualization of radar data from a new type of radar devices, control of cameras at observation points, monitoring of system components, and more.
