Latrine

Locus Map Android GPS live tracking server script

Latrine is a minimalist GPS live tracking server script. It is very easy to set up and requires no database. All you need is a web server which can execute Perl scripts.

More information on the live tracking feature of Locus Map Pro can be found on its documentation web page.

Features

• Tracking: Server receives data from Android device with Locus Pro installed and live tracking enabled.
• Live following: Data sent by Locus Pro is shown live on map.
• Multiple map layers: Currently you can choose between OpenStreetMap, OpenCylceMap, Hike and Bike (with Hillshading) and ESRI
• Multi-user: Authentication with key

Functions

Authentication is done with a key. Anyone who knows the key can see and update the GPS location. Your key must be at least 5 characters up to 15 characters a-zA-Z0-9_.
