A 3D indoor routing service with 2D visualization based on the multi-layered space-event model

Abstract

In this chapter the draft for a novel conceptual model for indoor navigation, the multi layered space-event model (MLSM), is combined with existing standards for Geo Web Services in order to define a framework for a 3D indoor routing service with rule-based 2D visualization. We prove that the MLSM in the test scenarios we defined can be used as a conceptual model for an indoor routing service. With the help of a prototype we also show that the MLSM needs some extensions if a 3D MLSM graph shall be visualized in 2D. Our case scenarios and visualization examples are based on an existing Building Information Model (BIM) of a specific building.
