Implementation of Geographic Information System with Dijkstra Algorithm Base On Mobile Application

Abstract

Padang is a coastal city, which is located opposite to the Indian Ocean. Just across Padang city there are areas of subduction, which can trigger a powerful earthquake and generate tsunami. Geologists have to say that the city of Padang is the area that is highly vulnerable to tsunamis in the near future. Several studies have been conducted to prepare Padang city for disaster. However, after conducting surveys and interviews with the Public Works Department City of Padang, most people didn't know the media for recommending the nearest disaster evacuation path. Evacuation is the most important method of saving people's lives. Disaster evacuation is analyzed for a given travel time and a specific inundation area, coastal area citizens need to evacuate to a safe place as soon as disaster occur, the prime evacuation time is very critical for them. Smart phones have become a primary social communication device during interactions in emergencies. This paper outlines the design and development of a prototype geographical information system for examining the pathways evacuation and give recommendation information, and collective actions in emergency situations can be accessed anytime and anywhere, with a map of the location and route, that people can estimate travel time, and evacuate people immediately in to a safer place. The results of this paper clearly showed the applicability and potentiality of using GIS as a tool in path analysis.
