QoS Based Design and Development in Spatial Data Sharing Platform for Disaster Management

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