Abstract:To mitigate the consequences of increasingly frequent disasters across the globe, better real-time collaborative disaster management tools are needed. In particular better stakeholder collaboration would allow the integration of different types of data from diverse sources, thus strengthening analytical capabilities and decision making for disaster response. When a disaster occurs, satellite imagery can provide reliable information quickly to assess the situation and the extent of damage. The International Charter “Space and Major Disasters”, in conjunction with intermediary agencies, provides for space resources to be available for disaster response. It is widely seen as a successful example of international humanitarian assistance following disasters, showing a growing number of activations and provision of image-derived information. However, the Charter is also facing challenges in its operation, especially with respect to accurate information delivery and type based on varying stakeholders and lacking integration and feedback of information from the affected area. This project, therefore, seeks to offer a solution to the current challenges by moving away from static map data provision to a more dynamic, distributed and collaborative environment by use of Geo Web Services. Geo Web Services brings together vast stores of data from heterogeneous sources, along with geospatial services that can be mashed-up and be used to create better information. The project looks in depth how heterogeneous disaster management agencies can work together in a loosely coupled environment and create new synergies. A prove-of-concept was developed to demonstrate the importance of Geo Web in collaborative mapping and real-time information dissemination by utilizing open source products aided by User Generated Content and Volunteer Geographic Information. A Geo Web Service architecture showed that geocollaboration and real time disaster mapping and management is feasible within the disaster domain. The project further compares other available virtual disaster viewers, and gives solutions and recommendations for the adoption and implementation of the architecture. Key words: Geo Web Services, Web Syndication, Web 2.0, Mashup, Crowdsourcing, User Generated Content, Ambient Computing, Ubiquitous Sensors, Neogeography tools, Interoperability, Service Oriented Architectures, geocollaboration, convergence, democratization.
