Discuss some of the inferences that may be made from location data that is personally identifiable (i.e. the user of the data knows the identity of the subject together with their location at particular times), and also discuss the inferences that may be drawn from the same set of location data when it is not (yet) associated with the identity of an individual. Basically, what I want here is a list of what can be learned, and a brief description of how each inference could be made..
