Figure 2. Configuration of the system 
Figure 2 shows the configuration of the proposed system. The 
Spatial-Temporal GIS is the system designed and developed by 
the consortium of DiMSIS, which is a GIS for managing 
disaster information (Kakumoto 1996). The imagery integration 
system is an extension of DiMSIS, including the support of 
KIWI+ format (KIWI+ 2003). It contains registration modules 
for the following sources: 
a. Aerial photo; with or without orientation data 
b. Orthogonal or satellite imagery 
c. Snap photo 
d. Video 
e. Simulation or analytical imagery; such as those from 
change detection systems 
4. DETAILS OF INDIVIDUAL MODULES 
The imagery integration. system consists of graphical user 
interface (GUI) and image processing modules. 
GUI includes dialogs for specifying necessary information 
required by registering all types of imagery into the system. 
Figure 3 and 4 are dialog examples for registering aerial 
imagery and video scripts respectively.

The information for coordinated imageries is summarized in 
Table 1. The imageries are restructured in a hierarchical way to 
ensure efficient display control, such as zoom in/out, pan. 
Compression option and its ratio can also be specified for 
saving of storage space.

Figure 5 shows an example of registered aerial image, overlaid 
with cartographical map. To absorb the displacement of image 
due to variation in DSM, function for adjusting image display 
position is also implemented.
