The integration databases should be constructed for the enormous information over the life cycle of civil engineering structures.
In this study, the environment where an integration database is controlled on the base of GIS and 3D CAD-Data are used. First, the Geodetic Reference Positions are specified on CAD-Data, and the coordinate system of CAD-data is transformed into the geodetic coordinate system. Next, the Geodetic-Schema is designed for standardization of data structure of Geodetic-Data. The CAD-Data are transformed into Geodetic-Data and output format is discussed.
