The quality and availability of positional information (location, orientation) is a key resource that strongly influences the way in which many systems incorporating spatial information can provide services to their user. In this extended abstract, we discuss a number of issues and ideas on how to cope with low-quality positional information, how to improve that quality and how integrating qualitative and quantitative approaches may be beneficial in this context. We present a number of examples from systems that we developed in the past and that we are currently developing, and we point out possible improvements.
