#Recording gps tracks how to
Consult your mobile device’s user manual if you are unsure how to change battery and/or system management settings.In this fast-paced digital world, there are applications designed to better each and every scenario that make our life smoother and flawless. Some mobile devices also have system management settings that may affect what an app is allowed to do in the background. Battery management settings vary by mobile device although commonly this can be fixed by turning battery optimization and battery saver settings off in your mobile device’s settings for the CalTopo app. This can be resolved by ensuring the CalTopo mobile app is allowed to run in the background with continued access to GPS. The straight lines occur because the app wasn’t allowed to access the GPS while the app was backgrounded so the track jumps from the last time the GPS was accessed to your current location, resulting in a straight line. The most common cause for straight lines in recorded tracks is aggressive battery management by your mobile device that restricts background access to the GPS or kills the app when it’s in the background. The Recover Track dialog that may also appear after the app has been in the background Examples of both of these are shown below. You may also see a Recover Track dialog with options for continuing, finishing or discarding the track. However you may notice straight lines in the track that don’t accurately reflect where you actually travelled, typically after the app has been in the background (such as when the screen is off and the device is in your pocket). The CalTopo mobile app uses your mobile device’s GPS to determine where you are when you use any of the app’s location functions, including recording a track. Troubleshooting Recording Tracks Why do I get straight lines when I record a track? Check out this blog post for a more in depth discussion of GPS accuracy as well as the results of an interesting experiment comparing 4 different devices! This, along with a huge range of other outside factors, can cause the resulting recorded track to differ from the planned route or recorded routes from other GPS devices or apps.Īlthough the overall accuracy is still incredibly good, these differences are expected and are a normal part of the experience of using any GPS product. Raw data for a recorded track (red) versus a trail traced using satellite imagery (blue)Īt this time, CalTopo does not do any smoothing when recording tracks in its own app. To begin recording your track, tap the 4 dot location menu in the lower right corner of the map viewer and select Record Track. If you did not have a saved map open, the process for recording a mobile track would still be the same. The screenshots below show the steps for recording a mobile track with a saved map open. If you wish to save your mobile track to a particular map, it is easiest to have the map open before you start recording your track. You can record a mobile track using the CalTopo mobile app with or without a saved map open.

Please refer to the previous lesson for instructions on how to download base layers for offline use. Remember if you plan to record a mobile track in an area without a data connection, you will need to download base layers for that area ahead of time in order to view your track on a map while you are offline. In addition we will also discuss GPS accuracy since we frequently receive questions about this topic from users. This lesson will cover how to record and manage your tracks using the mobile app. You can also view data about previously recorded tracks such as the elevation profile as well as navigate the track in both forward and reverse directions. While you record your track, you can display information such as elapsed time, distance and elevation gain. Any track recorded with the mobile app will be automatically saved to your account and can be saved to a specific map. You can use the mobile app to record a track as you travel your route.
