 +== What does it mean for an object to be at location? =
 + 
 +Given the frequency of updates, and the accuracy of the reading, an object exists in a probability polygon. A lat/long may put the person in the vicinity of their homeAn error estimate of at least 20 feet means the person could be anywhere in the home. There are lat/longs that are impossible for people to be ininside of walls for instanceSo probability changes. Without the benefit of house plansthe first time traveling over a path defines that path as a >0 probability (openstreetmaps does this)
