6. CONCLUDING REMARKS 
How to make an effective system in preservation of cultural 
properties was described from photogrammetry and information 
processing points of view. 
To express structure drawings and images more intelligibly, 
their three-dimensional solid figures (Isometric Drawings) and 
CG were developed in a spatial three-dimension by using 
Digital Photogrammetric Workstation. By using this system, it 
becomes easy to obtain advice from cultural property experts 
with a higher cultural appreciation. 
In this paper, by combining huge shape information with 
various drawing information for maintenance purpose, a 
integrated management system by using CG and 3-dimensional 
management system has been developed. By using the personal 
computer, additional information can be inputted easily and 
three-dimensional shape can be displayed quickly. Moreover, 
the system has been applied to the Atomic bomb memorial 
dome, and the possibility of three-dimensional preservation 
management was introduced. As the results, conventional two- 
dimensions maintenance management and repaired condition 
records can be visualized into three-dimensions, therefore, 
planning and consideration related to preservation activities 
become easier. 
The 3-dimensional GIS information management system used 
in this research can be utilized in many fields as an effective 
tool for preservation and maintenance management as well as 
cultural property. By making damage condition and repair 
history information feed back to a repair plan, a real time three- 
dimensional visualization can be performed and a more rational 
repair plan and construction can be achieved. In future, this 
system can be greatly utilizable as a tool of observational 
construction method to the maintenance management society.
