 +== What does it mean for an object to be at a 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 homeThere are lat/longs that are impossible for people to be in, inside of walls for instance. So probability changes. Without the benefit of house plans, the first time traveling over a path defines that path as a >0 probability (openstreetmaps does this)
