You can now navigate back to the Main Screen or any other screen For each trip two files will be generated One is a GPX file that contains the vital Waypoints data and statistics GPX is an open standard XML data interchange format and many applications can read this file An XML file is a simple text file in a easily readable form for both machines and people The GPX filename that is displayed is a unique name that is based on the date and time timestamp The file extension gpx For e g 2012 Mar10 1905 gpx This file was created on 2010 October12 at 19 hrs and 05 minutes The second file is a KML files and has kml extension This is a special file that contains the trip points that can be displayed in Google Earth Again a kml file is an open standards XML file understood by many Location Based Applications LBS The KML file also has a unique name based on the date and time it was created It has an extension of kml For e g 2012 Mar10 1905 kml This file was created on 2012 March 10 at 19 Hrs and 5 minutes Both the GPX and the KML file names can be changed if the user decides to do so The next field is the Sampling Frequency in Minutes This specifies how often the Waypoints are marked and stored This is a TextBox where the user can enter a valid sampling value te es For example a sampling frequency of 1 Minute specifies that trip locations are marked every 1 minute A value of 0 25 minutes specifies sampling frequency of 15 second
