Integration of knowledge, visualization and dissemination of spatio-temporal data through geoportal systems

The article describes the basic requirements for the integration of knowledge, visualization and dissemination of spatio-temporal data through geoportal systems. Evaluation of the effectiveness of the implementation of the designed geoportal interfaces is carried out. It was shown that the main advantages of geoportals are considered the absence of the need for additional use of special programs, access at any time from any location, the ability to integrate with third-party websites, etc. The proposed structure of the platform solution is determined by the hypothesis that in order to optimize the storage processes and practical use of spatial data, a project-oriented spatial data infrastructures (SDIs) should contain loosely coupled and strongly connected storage subsystems, analysis and synthesis, as well as visualization and dissemination of spatial data; external objects in relation to SDI should be key actors, as well as external consumers and third-party providers of spatial data and information. Geoportal systems are the external part of the SDI and are used to disseminate and visualize the accumulated geospatial information and analysis results during design work. Solving the main issues of creating the infrastructure of geoportals makes it possible to create a successful strategy for the sustainable development of regions.
