Abstract :
This paper aims to describe development of a Web-based spatial data sharing platform for disaster management. Alongside functionality, quality of image(IQ) is basic to successful sharing of distributed geo-services.This paper explores IQ provisioning in the context of geo-service sharing for disaster management.The paper presents an IQ model for disaster management and illustrates how user level IQ requirements can be supported in IQ-aware geo-service architecture. In contrast to context-specific IQ assurance approaches, which usually focus on a few variables determined by local needs, this approach provides interactive, multi-granularity and contextsensitive IQ indicators that help experts to build and justify their opinions. The prototype system was designed and validated by enhancing IQ generated by remote sensing through the technologies of visualization.
