Are indoor positioning systems mature for cartographic tasks?

ABSTRACT: Better indoor mapping are linked together with better indoor positioning. This paper gives a brief overview over existing methods for indoor positioning. To get an impression of how well a WiFi based commercial indoor positioning system works as an input to indoor real time visualization, a network of control points were established. Accurate coordinates for existing access points were also measured to see if these could improve the WiFi measured coordinates. Our experiment indicates that the geometry of the access points/mobile platform, the nearness to the access points and obstacles, as for example walls, are the dominating limitations when it comes to measure more accurate positions.
