摘要：This paper describes the development and implementation of a location based service fortsunami evacuation routes. Based on the position of the mobile phone the system provides areal-time calculation for an escape route out of the hazard zone. A smartphone applicationvisualizes the route on a map. Nowadays, tsunami hazard zones are well known anddetermined with complex simulation models. Evacuation routes in such hazard zones aremostly sign posted along roads and visualized in evacuation plans. People who are inside atsunami hazard zone have to make themselves familiar with the evacuation plans and haveto find their own way out of the zone. The developed concept shows the possibility of alocation based service to determine an escape route and visualize the result on a map. Inaddition, the route is the shortest possible way out of the zone. The concept is implementedfor a test area in Christchurch, New Zealand. The developed prototype consists of a threetier architecture. The mobile Android application (client) determines the position of thesmartphone and is responsible for the visualization of the result. A calculation program onthe server side calculates the shortest route out of the hazard zone. The necessary data forthis calculation come from a spatial data base which is the third component in thisarchitecture. The whole system allows the user to calculate an escape route out of thehazard zone at the touch of a button. Implemented in an existing tsunami warningapplication it would be a life-saving service.
