METHOD FOR EXCHANGING DIFFERENT TYPE OF DRAWING DATA TO OBJECT-RELATIONAL TYPE GEOGRAPHIC INFORMATION SYSTEM

摘要

PURPOSE: A method for exchanging different type of drawing data to object-relational type geographic information system(GIS) is provided to use drawing and facility information data built by another GIS or drawing drafted by CAD system even with GIS for facility management using GEUS by exchanging drawing data such as data exchange format(DXF) or shapefile to data of data base management system(DBMS) for object-relational type GIS like GEUS. CONSTITUTION: The first stage is that initial environment is set up inputting(501) database name to be created at DBMS for object-relational type GIS and file name of drawing data to be exchanged. The second stage is that attributes having space data type defined in class and class reading through drawing data file to be exchanged is defined(503) at database of DBMS for object-relational type GIS. The third stage is that drawing data file to be exchanged is exchanged(506) into space data provided from DBMS for object-relational type GIS extracting space data, reading again drawing data file to be exchanged. and the exchanged space data is stored(507) at database of DBMS for object-relational type GIS. A recorder is provided to be able to read it by computer.
