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.

State-of-the-art means for decision-making intelligent support at dispatching the geospatial processes of the sea transport that implement digital cartographic data sets do not allow an operational and adequate enough account of the natural environment changing properties affecting the dispatching decisions made at a control of complexly distributed totalities of geospatial processes. At that the dispatching is the final manifestation of a multidimensional control process of geospatial processes on the sea surface. Conventionally, a control problem of the sea transport objects' that realize geospatial processes is being solved in isolation from the accounting for a current state of the marine environment and for the variability of its hydrological, hydrophysical and other characteristics. As a rule, only issues of changing the hydrographic and hydrometeorological conditions are subjected to consideration as they concern the maritime safety and navigation specifics. Now the more complex version of the spatial processes dispatching problem is of great interest, when the environment variability defines the unique dispatching conditions in each point of the coordinated geographic space. Such problem's statement is especially actual under the circumstances of implementing the up-to-date adaptive monitoring and natural environment probing means, like subsystems for surveillance of the matching spatial sea processes dispatching systems. The above statement novelty as well as an approach to this version of the problem solving is in a fusion of data pertinent to the spatial processes representation area and data matching the typical models of digital data sets, integration of software mechanisms used to arrange for a proper work with information about geospatial processes and programs of dealing with cartographic data sets. Development of a reasonable formulation and method for solving the given version of a problem forms the essence of this paper.

The scientific and methodological tools of geochronological tracking have found the widest application in retrospective studies of the features of the use of individual products of high technology and expensive technology of various types. Subject of study. The results of such studies are the basis for organizing service, building logistic supply schemes, deploying supply networks, etc. The feasibility of such studies is especially relevant today for products of domestic hydroacoustic equipment for civil purposes. Meth-od. The competitive state of the responsible industry of precision marine instrumentation objectively re-quires a systematic approach to studying the characteristics of demand and application for these prod-ucts. Main results. It is the geochronological tracking toolkit that can become the basis for a new ap-proach to planning the promotion of products of domestic hydroacoustic equipment to the Russian and in-ternational markets. Practical relevance. The proposed information technology will make it possible to achieve an increase in efficiency in organizing maintenance processes and maintaining the technical readiness of expensive hydroacoustic equipment. This article is devoted to the consideration of the quali-tatively new capabilities of the specified tools, as well as the rationalization of the corresponding algo-rithmic apparatus.
