2. OVERVIEW OF THE JOINT PROJECT 
The project of “Special Project for Earthquake Disaster 
Mitigation in Urban Areas” is initiated by The Research and 
Development Bureau of Ministry of Education, Culture, Sports, 
Science and Technology. It started from August of 2002 and 
schedule for three years, extensible to five years. It consists of 
three core projects as follows. 
(a) Prediction of quake pattern 
Studies the crust structures of metropolitan cities. 
(b) Improvement of quake resistance 
Studies the technologies for improving quake resistance using 
shock stand of large scale, with the cooperation of ten sub- 
teams. 
(c) Optimisation of rescue strategies 
Optimises the strategies for rescuing victims (19 sub teams), 
the infrastructure with rescue robot (11 sub teams). 
(d) Integrated earthquake disaster management 
Study the policies and regulations related to earthquake 
prevention for earthquake — disaster 
management 
The authors' research team belongs to the third core project and 
emphasizes on data collection and information retrieval. Here, 
data collection aims at registering and managing live data 
collected during disaster management activities. Data can be 
either multimedia data such as aerial imagery, satellite imagery 
disaster integrated 
of high resolution and video data, or document files as 
generated by DTP or spreadsheet applications. Information 
retrieval aims at providing user with data inputting, searching, 
analysing environment, based on the results of data collection. 
3. CONFIGURATION OF THE SYSTEM 
Figure 1 is the result of researches by author's group during the 
first stage of the project. It shows the information and actions 
for disaster management. Especially during the initial stage of a 
disaster, the most direct and informative resources are all kinds 
of imageries including video. The functionalities of imagery 
integration proposed and implemented in this paper facilitate 
the usage of imageries, either by independent view, or 
integrated with vector data in a GIS. The functions also include 
image processing modules that convert simulation or analysis 
result in raster image format into vector format, for more 
efficient and precise analysis with existing GIS functions. 
Since both geographical and temporal factors are as important 
for observation and analysis of events after a disaster, all the 
imagery information is registered as spatial-temporal objects. 
To enable the coexistence of imageries of different resource, 
and for the same area, all the coordinated imagery objects have 
the attributes of transparency and mask colour.
