Information technology of the geochronological tracking is an assembly of processes that accumulate and integrate data about geographic relocation of ships, figures for a given time interval and represent the results as a generalizing graph in GIS. Hypotheses on the stable tendencies in migration could be represented as the above graph's sub-graphs. Such tendencies testing is reduced to the search and evaluation of the statistical significance of the matching graphs isomorphism. Full-featured development of computer interpretation of the graph theory methods based on geochronological tracking provides new quality of research using modern GIS-tools. Namely, researcher can use the quantitative methods of the corresponding logical-analytical apparatus. The proposed paper deals with a consideration of qualitatively new possibilities of such approach and the corresponding algorithmic apparatus. Dispatching for geospatial processes of maritime transport with implementation of geochronological tracking tools is tightly related with completion of more developed model of data processing in the automated vessel traffic control system. The proposed model is focused not only on each vessel's data processing but also on spatial situations tracking based on the data of geographic theatre. This is the main feature for implementation of software component of geochronological tracking for dispatching of geospatial processes for maritime transport. The article is dedicated to the thorough consideration of this feature.Keywords: Geographic information systems, GIS-technologies for historic research, geochronological track and tracking, graphs isomorphism, optimal algorithm, GIS-based interdisciplinary research.

Geochronological tracking is an effective information technology for digital cartographic spatial data sets processing. It is widely known in retrospective patterns research about geographic relocation of figures, or any other units for a given time interval. Software component of geochronological tracking is becoming one the most popular GIS-integrated applications. The article presents the basic provisions for the algorithmization of the geochronological tracking procedure for statistical testing of retrospective studies hypotheses. We can observe the results of solving this optimization problem in a general form and in a number of the most typical variants. The obtained results of solving the optimization problem are interpreted in terms of the retrospective studies subject area. There are shown the ways of further practical application of the optimized algorithm in the tasks of modern logistics, data mining and formalized knowledge.

Scheduling of geospatial processes of vessels is one of the most important processes of ensuring the navigation safety and efficiency of the water transport. It represents the control and coordination of management of geospatial processes of the water transport (i.e. the processes of ship traffic in time and geographical space) to achieve the highest indicators of effectiveness, implementation of traffic schedules, the production program and other parameters at unconditional fulfillment of the navigational safety requirements. Feature of the water transport scheduling is a constant change of situation, adjustability and some inconsistency of schedules, ship traffic schemes, etc. The main objectives of the water transport scheduling are monitoring the navigational status and safety of moving vessels, following the plans and schemes of the movement on the water areas. Modern, effective scheduling of the water transport means a realistic balance between the purposes of navigation (geospatial) safety and the production purposes.Opportunities for situational management realized within scheduling of geospatial processes of the water transport allow to increase the effectiveness and improve the quality of the country's fleet operation. Scheduling by spatial processes of the water transport using situational management tools and digital cartographic data sets is closely connected with the implementation of more developed data processing model in automation complexes for controlling the ship traffic. The model offered in the paper is oriented, in particular, not at processing data about each vessel, but at tracking spatial situations against the background of data on geographical theater, as well as assessing their danger. It is in this the implementation of the informational component of situational management for scheduling the geospatial processes of the water transport is being represented, and its informative disclosure is considered in the paper.Keywords: Scheduling the geospatial processes, situational management, digital geospatial data, spatial data, water transport.
