Modern requirements for urban planning documentation and urban cadastre system include, in particular, the formation of geospatial profile data sets in a single system of classification and coding of urban planning objects, which together with metadata sets are registered in databases of urban cadastre information system.
But so far there is no holistic system of normative documents for regulation of types of geospatial profile data sets, catalog of geospatial objects classes, conceptual and logical models of geospatial profile data sets, no requirements for digital formats and coding of components of urban planning documentation , storage, retrieval and use in the system of urban cadastre, so far dominated by a graphical approach to the production of documents, focused on the preparation of spatial schemes of cartographic images, rather than their GIS models.
The absence of the listed components of the system of normative documents on geospatial profile data sets of the master plan does not allow to pass from automation of preparation of cartographic documents to geoinformation model of projected decisions for GIS of territories management and integration of information resources into national infrastructure of geospatial data.
Methods
Geospatial profile data sets (GPDS) can be defined as a unified set of geoinformation models of objects contained in the spatial schemes and plans of urban planning documentation and project documentation in the state geodetic coordinate system USK-2000 and a single system of classification and coding of construction sites for formation of urban cadastre databases.
Modern geographic information systems use three main models of geospatial profile data sets in GIS: file geoinformation model (FGM), georelational (GRM) and object-relational (ORM) [Maksymova Yu. S., 2017].
Although these models have evolved from a file to an object-relational model, they are still used in GIS.
If we talk about file and georelational models, their structure, content and means of intellectualization in the form of procedural knowledge of applied modeling remain platform-dependent, and therefore limited opportunities for both exchange and transfer of knowledge from the designer to the computer. Conceptually, only ORM, which combines both basic geospatial data in independent formats and basic and applied functions of behavior modeling independent of instrumental GIS, provides the implementation of geospatial models and spatial analysis software regardless of the GIS platform.
Thus, the key hypothesis of the exploration is based on the fact that the use of object-oriented model of gepspatial profile data sets based on OR DBMS allows to maximize the level of unification of attributive and spatial data and the level of unification of geoinformation data analysis (Fig. 1). The core of the technological model of formation of GPDS of the master plan, presented in Figure 2, is: the database of the master plan objects; a block of applied tools of spatial analysis and modeling of GPDS objects, which interact both with the database of master plan objects and with the tools of instrumental GIS; tools of instumental GIS.
The database of master plan objects is the basis of modeling and a source for formation of digital schemes according to certain rules of mapping and formation of images of electronic schemes in GIS.Tools of instrumental GIS provide communication with the database of master plan objects and by results of geoinformation modeling in the automated system of master plans GPDS (fig. 2) such components of documentation in the exchange data formats are prepared for transfer in to the registration system of urban-planning cadastre: master plan geospatial profile data sets;sets of electronic raster plans (schemes) in accordance with the requirementsDBN B.1.1-15:2012; text materials (the form of technical and economic indicators is generated by the system automatically); metadata about the set of documentation and its components, including GPDS; application scheme (with a description of the data structure and classification system used).
