摘要：This paper presents the results of imagery integration in disaster prevention system for the project of "Special Project for Earthquake Disaster Mitigation in Urban Areas". The proposed approaches differ from existing ones as follows: support registration and spatial- temporal management of (a) original aerial imageries, (b) images of other resources, such as raster result of all kinds of manual or automatic analytical results of the original aerial imageries, (c) video and snap images. Functions for vector conversion for images analytical result, such as extraction of changes, are also provided for further analysis with GIS functionalities. For imageries of high resolution and therefore huge size, they are hierarchically restructured for high access speed. Initial evaluation tests with the prototype system of the above specifications show that the system can build up multimedia database within a few hours for timely spatial decision support. The accessibility and comprehensibility of multimedia database is superior to those of the existing systems
