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

摘要

A method for searching a CAD(Computer-Aided Design) drawing file by using a GIS(Geographic Information System) space-linked database is provided to prevent damage of an original form of a CAD drawing, prevent duplicated file management, and reduce time, manpower, and expense needed for constructing the GIS space-linked database by omitting correct position and structure editing processes in a GIS space-linked database construction process. A CAD drawing is automatically extracted and constructed without inputting any GIS attribute(S-1). A position of a mouse cursor resized and moved in a GIS is traced, and concrete facility information of an object pointed by the mouse cursor is searched and displayed by using a GIS space-linked database(S-2). Files related to the object are searched from the GIS space-linked database and a list of the searched files is displayed on a screen when the object is selected from a facility(S-3). The file is displayed in the screen when the file is selected from the list(S-4).
