Optimum Site Selection for Fire Brigade in Ella, Sri Lanka by Utilizing GIS

Abstract

As an island nation, Sri Lanka is facing different disasters while the forest fire disasters that are dominant in the highlands of the country are significant. In the Ella neighbourhood, forest fires occur every year near the end of the dry season. Further, the absence of other fire stations near the area is a considerable issue and under the investigation found a suitable location for the forest fire brigade and analysed the network connectivity to the selected location from any place of the Ella. To find the best placement for a fire station, a site selection analysis was performed in a GIS context via weighted overlay analysis. As the data sources of the study population, Land use land cover, elevation, water sources, road, building, pre fired area, and pre-hazardous areas were utilized in the ArcMap 10.5 software platform through spatial analysis tools and network analysis tools. For the determination of weights for each factor, the Analytical Hierarchy Process was used as the main statistical technique of the study. Finally, the selected areas were examined via visual validation in Google Earth and selected the most suitable location for fire brigade establishment along with the network analysis. In addition, the establishment of the fire brigade is crucial in the central part of the country due to the magnitude and the frequency of the disaster. Further, the proposed study can be utilized as a comprehensive guideline for any organization before the establishment of the fire brigade
