Abstract
Purpose. The purpose of the research is development of an object-oriented geoformation model of settlements master plans geospatial profile data sets. The topicality of the research is due to the need to meet the current requirements of the legislation on the development of geospatial profile data sets as, considering the importance part of master plan documentation of increasing the level of automation and level of master plan digital data quality for their further effective use in the urban cadastre system. Methodology. The basis of the master plan geoinformation model development methodology is a traditional approach to database (DB) design, which includes levels of conceptual, logical, and physical modeling. For conceptual modeling UML (Unified Modeling Language) is used, which is recommended as the main modeling tool in the geographic information / geomatics complex of international standards. A software tool that supports the interactive mode of creating UML diagrams Visio is used. For implementation of the master plan geospatial data base and the behavioral component of the geoinformation model, the expansion of the standard language SQL99 with the new geometry data type and built-in functions that provide storage, processing, and analysis of geospatial data in relational database management systems are used. The proposed models in the research is realized in the object-relational DBMS PostgreSQl / postgis and geographic information system QGIS. Results. The typization of the geospatial profile data sets’ organization models is done in GIS. The advantages of object-relational data model for the preparation of geospatial profile data sets in the framework of the master plan were substantiated. A technological model for the formation of geospatial profile data sets based on the geospatial data base of the master plan objects data base was proposed and implemented. An example of the implementation of methods for the master plan restrictions zones automated construction using SQL-function is given. Scientific novelty. The master plans geospatial profile data sets formation model was developed, based on the integration of object-relational databases and geographic information systems and master plan’s geospatial profile data sets object-oriented model was developed. Implementation of which in the object-relational DBMS ensures data independence from means and formats of instrumental geographic information systems. Practical significance. The proposed master plans’ geospatial profile data sets object-oriented model provides for an efficient increase of creation and use of master plans geospatial profile data sets in the urban cadastre.
