SPEX: Stay Point EXtractor.

positional arguments: filename Trace file name output_location Output folder location

optional arguments: -h, --help show this help message and exit --action {extract_points,extract_metrics,extract_both} Choose what action to do. -t [T] Time threshold (in minutes) -d [{haversine,euclidean}] Distance function (haversine or euclidean) -r [R] Radius threshold (in meters)

Usage examples

python spex.py my_trace.csv my_output_folder/ --action extract_both

• (Extract the stay points and the metrics from the my_trace.csv file and store the stay points in the my_output_folder, using the default values of time threshold (30 minutes), radius threshold (500 meters) and distance function (haversine)

python spex.py my_trace.csv my_output_folder/ --action extract_metrics

• (Extract only the metrics)

python spex.py my_trace.csv my_output_folder/ --action extract_points -t 60 -d euclidean -r 1000

• (Extracts only the stay points and sets specific values for time, radius and distance function)
