Interoperable 3D Emergency Routing Based on OpenLS

In this paper we introduce the concept and the implementation of an Emergency Route Service 3D (ERS3D), which is based on the already established OGC Standards OpenLS and which further covers the following two aspects: Firstly, the possibility to bypass restricted areas or closed streets during disaster situations and secondly the ability to return a 3D route geometry that can be integrated into a 3D application. Within the project OK-GIS (Open and free GIS for Disaster Management) a Route Service based on OpenLS Specifications was implemented. This was then taken as the basis for building more complex services. Based on the initial Route Service an Emergency Route Service (ERS) was developed, along with a 3D Route Service (3DRS). The combination of the 3DRS and the ERS then resulted in a 3D Emergency Route Service (3DERS). An important aspect is that this can be achieved solely using OGC standards, so no further standards need to be specified for this application. Moreover this shows that more complex services can be realized by combining existing OGC services and integrating them into a 3D spatial data infrastructure.
