Formalization of Life Cycle Stages of Geographic Information Products Creation at Research and Production Enterprises
Purpose of research. The purpose of this article is to formalize the processes of creating geographic information products (GIP), within its life cycle (LC), taking into account heterogeneous types of GIS resources of a research - production enterprise (RPE). A typical subsystem of AIS infrastructure of an enterprise is an object of this study. Methods. On the basis of an analysis of scientific sources and standards it was shown that changes in traditional approaches, principles, models are necessary in the creation of GIP. It is also necessary to change infrastructure and resources management of NPP. Presented in tabular form model is describing GIP life cycle taking into account the list of required resources and provisions. Features of LC GIP based on geoinformation technologies processes have been identified. The general approach in formalization of stages describing processes of GIP processing and operation of typical elements of GIS enterprise is described. A model of automated processing process (APP) of GIP is developed on the basis of system representations and theoretical-multiple approach. It is represented by the Cartesian product of vectors. The role and features of information support in the development of GIP are highlighted. Results. The analysis of GIP functioning features, as well as developed structural graphic and tabular presentation, made it possible to identify links between GIP features and stages content of their LCs. The results will allow clearer positioning of GIP elements and components presented for development and operation, especially in GIS NPP. The results will provide an opportunity to define the requirements for systems of this class adequately. Conclusion. The presented LC GIP models, taking into account the identified features of their construction and functioning, will allow, in the future, setting and solving modeling and management system tasks of this class.
