OpenLocation

Track your position / Where are your friends?

Description

Track your position / Where are your friends? OpenLocation periodically sends the location of your android-phone to a web-server. Both client and server are open source so you can host the database (which contains all your previous locations) on your own server. Sample server on: http://location.h3ndrik.de

How it works

OpenLocation will keep track of the following information:

your location
your altitude, speed and bearing
how the data was obtained (GPS, triangulating over cell-towers/wifi, ...)
a timestamp and the current ip-address of the client

The android-client will cache every position information obtained by the system and periodically send them to the server. This should be implemented in a battery-conserving way. E.g. OpenLocation uses the location data of the network or data that was requested by other apps anyhow. Only if there is no data for 15min the app will get active. Data will be transferred if the internet connection is active anyhow, but at least once every 20min (and at most every 5min).
