The use of GIS-based network analysis capabilities for location-aware emergency messaging: a prototype application

The relevance of this paper lies at the crux of any urban emergency response infrastructure. The effectiveness of any emergency response system depends greatly on both the information content of the message that is relayed by first responders as well as the time window that the system operates in. The system developed in this project will try to address this gap by enabling a centralized emergency authority to transmit location-aware situation assessment of any specific emergency event.

According to Morrow (1999), disaster vulnerability is a social construct, and similarly, urban civic emergencies are ubiquitous across the world.
Although a number of natural and potentially anthropogenic hazards may exist in a specific location at any given time, the scale of vulnerability comes into existence when people are exposed to such hazards. With an increasing number of people coming in contact with potentially hazardous natural and anthropogenic disaster prone situations, emergency management efforts need a suite of information needs to cope with such situations. Any emergency management and disaster mitigation plan therefore needs real-time and detailed information on the location, information of the quantum of risk involved and the number and nature of people at risk to that specific situation. Integrating such information in quantitative, qualitative and locational terms is the ambit of geographic information system (GIS) enabled decision support systems (DSS) (Contini et al. 2000).
Similar to information needs for emergency planning; civic authorities usually grapple with increasing urbanization and the delivery ...

4.5. Messaging
On clicking ‘OK’ on this dialog, the items selected are written to a text message, the algorithm cycles through each feature theme representing each class of responders (police, hospital and fire-stations for 911 type calls and civic authorities for civic amenity requests) and finds the facility closest the event location. Each unit nearest to the event location is selected on the basis of the cost specified in preceding steps. After the algorithm runs its course, it shows a message that says “Emergency messages sent” and exits. The routes for each unit of each facility are drawn on the display for reference purposes. An example of a typical text message to a hospital is as follows.
