GPS Data Preprocessing
I got gps traces of busses which traveled from one place (bus station) to another. This file contains relevant(eg:- Data recorded between the starting bus station and ends with the destination stop) and irrelevant GPS traces(eg- traces recorded from bus station to the home of the bus driver). All the data of the month is in the same file. Looking for a efficient preprocessing technique to separate journeys from the file. The data fields in the files are "timestamp", "lat","lon". Can somebody suggest any techniques for this preprocessing step?
