Development of Methods for Extracting Space Information from 3D CAD

The aim of this study is to establish plans for transferring information to GIS System by extracting general space information on public buildings. For this purpose, conducted researches on studies on object oriented 3D Data and collected information on plans for extracting 3D data, plans for exchanging data between systems and the status of using object-oriented 3D Data. I studied visualization of space information and methods of exporting property information based on these studies on papers. I analyzed 3D space data structure of ArchiCAD and IntraMap and decided methods of integrating 3D CAD and 3D GIS.
