Pro users are able to plot placemarks with improved accuracy using the new Plot GPS Average tool. Plot GPS Average is a tool in which the users' fixed location can be determined with a possibly higher degree of accuracy (dependant on location, number of satellites in view and possible interference) by sampling the users' location over a period of time and then creating an 'averaged' location coordinate from the collection of sampled points.
Plot GPS Average can be accessed from map tools (three dots icon) on the map toolbar.
How it works
The Plot GPS Average tool has two modes with which to plot an average point; manual and timer. The tool starts in manual mode. These modes can be accessed by tapping the gear at the bottom right. Manual mode allows the user to drop the placemark whenever they see fit (15 seconds, 30 seconds, 2 minutes etc). Users will see the number of GPS fixes in the average and the duration. They will also see all the location fixes in the form of coloured dots around the location dot.
If users choose the ‘Timer’ option, they can then set the length of time the timer runs for. The shortest time a user can choose is 15 seconds. Once the length of time is chosen, hit ‘Close’ to go back to the tool.
Once the timer setting is chosen, users may have to wait until the timer is ‘Ready to start’. The user can then start the timer with the green start button. Users will then see the number of GPS fixes on average and the duration. They will also see all the location fixes in the form of colored dots around the location dot.
Due to popular feedback, users also have a third option, which allows them to specify a specific number of fixes to sample over (between 30 and 1000). Once the number of fixes is specified, press the green button to start recording the placemark average.
If there is an unstable average, then the user will see ‘Unstable Average’ below the coordinates. They can tap the ‘i’ to get more information. More details will be provided in the message that appears.
If there is a stable average, then the user will see ‘Stable Average’ below the coordinates. Users will need to have at least 30 fixes in order to see ‘Stable Average’. More information can be provided by tapping the ‘i’ beside ‘Stable Average’.
Users also have the option to restart the Plot GPS Average tool, with the orange refresh button. This will reset all fixes and start the tool again. This can only be used while the tool is running before the placemark is dropped.
If the tool is in manual mode and the user is satisfied with the number of fixes, the status of the average (stable vs unstable), the user can drop the placemark by tapping the placemark icon to the right. Once the placemark is dropped, the user will be taken to the Edit Placemark screen where they can edit the information of the placemark.
If the tool is in timer mode, once the timer is up the tool will automatically drop the placemark, and the user will be taken to the Edit Placemark screen. All of the information from the Plot GPS Average tool will be displayed within the ‘Description’ field of the placemark.
