A DATABASE FOR LINK OF SERCH DATA IN GIS SYSTEM, A BUILDING METHOD

摘要

A method for automatically constructing a database linked with a GIS(Geographic Information System) space by using a CAD(Computer-Aided Design) drawing is provided to build a shape file by maximally utilizing information included in the CAD drawing, and omitting location and structure editing processes in a GIS system construction process. A shape file is obtained by converting a CAD drawing including an individual or complex facility to be built into a GIS shape file format. CAD drawings, document, moving picture, and image files are integrated and classified into each folder according to a classification system. Match information between a CAD drawing and a GIS is extracted from the CAD drawing, and a database is constructed by using the match information. The shape file is obtained without performing location and structure editing processes regardless of close, cross, and topology errors of a polygon in the CAD drawing to keep an original form of the CAD drawing.
