RAnz
RAnz is a .nmea GPS file processor for riders developed in java. RAnz processes .nmea GPS files and extracts statistics from that information such as best time, best lap, distance, etc. at the same time that shows you the trace of your route. It is the best way of keeping track of your trainings and see how much you are improving. All information will be stored in a MySQL database so do not worry about losing it!
Uploading .nmea files to RAnz
Once you've started RAnz you will be directed to its main window where clicking on session -> load session will give you the opportunity to upload your .nmea file so RAnz can analize it.
After selecting your file, RAnz will ask you to click on the starting point of your session so it can have a starting point to base all its statistics.
From here you will be able to check the statistics of your session based on laps giving your information such as you best lap, worst time, fastest trace etc.
You also have the option of selecting inividual or several laps to show on the panel and get information just about those laps.
