Abstract: A first set of traces is received by a device, each trace including a set of location data. Each set of location data includes an origin point, a plurality of intermediate points, and a destination point in an ordered sequence. A bounding box surrounding a trace of the first set of traces is drawn, the bounding box corresponding to endpoints of the trace. A function determines a threshold and classifies a trace as stationary or non-stationary. A trace is classified as stationary or non-stationary by comparing a ratio represented by the trace length divided by the bounding box diagonal length to the determined threshold. In response to classifying the trace as stationary, the trace is labeled as stationary. In response to classifying the trace as non-stationary, extremities are extracted from the trace for re-classifying.

Abstract: A trace comprising location data about a computing device is received at a mapping server, where the trace stores the location data about the computing device in an ordered set of points. The origin and destination of the trace are obscured. Then, the trace is then separated into a set of subtraces by dividing the received points of location data into a set of subtraces, and removing the links between subtraces of the set of subtraces. For example, subtraces can be divided based on size, distance, elapsed time, or features of interest present in the location data.
