Overland is a passive GPS tracker for both iOS and Android and which can record geo-location data in user-specified intervals/accuracy and sends it to a server of the user's choice that has been developed by [[Aaron Parecki]]. The source code for [https://github.com/aaronpk/Overland-iOS iOS] and [https://github.com/OpenHumans/overland_android Android] versions is open source. 

== Data recorded by Overland ==
Besides the GPS coordinates, Overland also records some additional information with each location recording: 

* Motion state (walking, running, driving, cycling, stationary)
* Phone's battery level
* If connected to a Wifi, the name of the network

User's can setup the desired accuracy of the location data that is recorded and also the frequency with which data should be recorded, to find a personal trade-off between accuracy, granularity and phone battery life. 

== Server setup ==
Overland is designed to push the location data in regular intervals to a server on which the data should be stored. As the Overland [https://github.com/aaronpk/Overland-iOS data structure is well documented], users can in principle write their own server to store the data in. Additionally, Aaron Parecki also provides [https://github.com/aaronpk/Compass Compass], an open-source server that works with Overland which you could host yourself.

If you don't want to host anything yourself, [[Open Humans]] also [https://overland.openhumans.org provides an integration for Overland]. This integration creates a private endpoint for users, to which they can send their location data which in turn is privately store it in their Open Humans account.

== Projects that used Overland ==

* [[Aaron Parecki]] is using Overland to [https://aaronparecki.com/ display his rough location on his personal website]
** Inspired by this, [[User:Gedankenstuecke|Bastian Greshake Tzovaras]] made [https://my-personal-api.herokuapp.com/ a small ''personal API'' tool that uses Overland in combination with Open Humans] to display current location on the web. You can see it in action [https://tzovar.as/ in the footer here] and [http://www.madpriceball.net/ in the header here].
* Bastian used Overland in combination with environmental noise data from his [[Apple Watch]] to [https://exploratory.openhumans.org/notebook/77/ find out where he encounters most noise].
** He also used Overland to [https://exploratory.openhumans.org/notebook/163/ explore how the COVID-19 lockdown affected his movements].
