A formal model of the synthesized screen image of dynamic situation in the areas of mobile objects monitoring and its implementation into the web-oriented geoinformation system

Based on the set-theoretic approach, a formal model is proposed for the synthesized screen image of a dynamic situation in areas of monitoring mobile objects. The essence of the model lies in varying the description of sets of aggregated static and dynamic objects that form the information filling of an adaptive dynamic scene with allowance made for the context of a given object domain. An algorithm is developed for layerwise visualization of the contextual cartographical background with the use of the types of cartographical objects that are singled out in the model. The model is implemented in a web-oriented geoinformation system of monitoring mobile objects that operates according to the MVC concept and has a client-server architecture. To implement it, the following complex of modern web technologies is used: PHP and MySQL on the server side and AJAX and jQuery on the client side. The module of addition/elimination of information on moving objects in a dynamic scene interacts with Google Maps Web Services without creating critical loads on the server side of the system. © 2017, Springer Science+Business Media New York.
