| Description | This paper deals with remote spatial data management in crisis situations through Web interface represented by the Web Feature Service; Transactional (WFST) client application. WFST is a service and specification of Open Geospatial Consortium that enables client application to alter the state of feature through insert, update, and delete operations. This way allows users to access mapping server(s) and database(s) through standard Geography Markup Language. Our approach is to use GeoServer as the mapping server technology and OpenLayers as the client system accessing both, mapping server and associated database. OpenLayers is an open source JavaScript library for displaying spatial data in Web browsers and providing an API for building rich Web-based applications. Here presented case study represents a client software for an officer in charge in a crisis situation. Through this software the most up to date spatial information from the place of the crisis situation to the headquaters can be sent. Communication between the server and the client application was realized and tested through three independent communication channels; direct internet connection to the satellite, wireless internet connection and GPRS. The officer in charge can thereby draw the areas covered by fire, points representing the position of rescued citizens or line of evacuation route, etc. This information is then sent and saved in the mapping and database server. At the same time it is possible to send additional data from the server to the client application; such as e.g. alternative evacuation route calculated with information from another officer in charge. This case study has been successfully tested as the part of the crisis management infrastructure for the process of hazardous materials transportation in November 2008. |
