Abstract: Method, mobile device, computer program product, and apparatus for performing Fine Grain Position Data Collection is described. In one aspect a mobile device performs measurement batching of data, for example positioning and AP measurement data. In some aspects, the mobile device processes positioning and AP measurement data in response to a batch trigger. The mobile device may send the processed measurement batch to a server for analysis or processing. A batch trigger may include receiving a positioning fix with high confidence such that the mobile device may backfilter or otherwise correct mobile sensor based positioning data associated with AP measurements. The server may interpret the data from the measurement batches identified from a number of different mobile devices to calculate position of APs within an environment.
