Building Modeling,ices. This chapter, therefore, explains building modeling and integrates basic algorithms for vector graphics and raster graphics, environmental models, navigation graphs, and location modeling. Furthermore, two approaches to standardization of environmental information for indoor location-based services are outlined: City GML and IndoorOSM.

Prerequisites, contains a detailed section on signal propagation and statistical models for signal propagation, which are behind several indoor positioning approaches. It further introduces the most important sensor systems, which can be used to infer the position of a mobile device in buildings.

Position Refinement,o measurements. Advanced systems can use time-series information for refinement including Weighted Least Squares, Recursive Least Squares, Kalman filtering, and particle filtering. The main results and algorithms get a closed explanation in this chapter.
