Disaster management system based on GIS web services

Disaster management system based on GIS web services exclusively designed to handle the disaster such as tsunami, flood, earthquake, cyclone etc. The necessity of the system is many people lives in danger because of lack of providing timely help to the affected victims and tardy response of relief works. Disaster management system incorporates with GIS web services to identify the affected areas and possible routes to reach the location. To the general public the system provides the information of getting the medical aid and relief materials to the deceased victim. In this paper, we have designed a prototype for disaster management system using GIS web service which envision of providing the required services to the needy people. The system consisting of three important services police, fire and medical has been developed using GIS web services and using AJAX (Asynchronous JavaScript and XML)approach the spatial data are integrated into the map. Since the spatial data are bulk in size, integration of GIS data with the map is a challenge for GIS developers. In the conventional process every time the request will be processed by the server and send back the response to the client. Since this is a time consuming process and the performance of the system will be deteriorated. To address this issue, the AJAX was introduced to integrate with the GIS web service. By integrating AJAX with GIS web services, the map and the spatial data can be loaded efficiently into the client browser and loading time can be minimized. Moreover, Quality of Service (QoS) optimization using fuzzy inference rule based approach has been introduced to select the best web service in case of similar service is available for same functionality in the internet. Using this approach QoS attributes of response time, throughput, availability and reliability of GIS web service are optimized and according to the user´s requirement best service will be provided to the client. The system also designed to su- - pport mobile environment.
