Latrine-Live

Locus Map Android GPS live tracking server script

ScreenShot

Latrine-Live is an enhancement to Latrine, 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 PHP 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 together with moving data. (all of locus possible data is supported)
  • Track History: The track gets recorded and displayed.
  • Multiple map layers: Currently you can choose between: OpenStreetMap, OpenCylceMap, OutdoorsMap, LandscapeMap, OpenTopoMap, Hike & Bike (with Hillshading), Google Hybrid and ESRI
  • Multiple map overlays: Currently you can choose between: Hillshading, Contourlines, Waymarked Hike & Cycling
  • Multi-user: Authentication with key
  • Dialog for key: If URL is given without a direct key, a prompt shows up for to enter the key
  • Disable Auto-Pan: Panning the map is active, as long as the popup is shown. When closing the popup, the user is able to en-/disable panning by checkbox
  • Delete files: It's possible to delete files on server by URL
  • Housekeeping: If not stored on /tmp device, the created files 'key'.latlaon & 'key'.geojson are kept as long as housekeeping time is set in latrine.php
  • Messages: It's possible to provide a variable 'message' within locus and send free text with your position and moving data

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_.

Show map

http://<SERVER>/Latrine-live/index.html?#<KEY>
or
http://<SERVER>/Latrine-live/#<KEY>
or
http://<SERVER>/Latrine-live/ (You'll get asked for KEY then)

Example:

http://localhost/Latrine-live/index.html?#OnMyBike
or
http://localhost/Latrine-live/#OnMyBike
or
http://localhost/Latrine-live/ (You'll be prompted for KEY then)

Installation

1.) Adjust the storage location my $store = '/tmp/latrine/'; in latrine.php.

2.) Adjust housekeeping time, if desired, in latrine.php.

3.) Adjust the location (URL) to your PHP script var phpScript = 'latrine.php'; in index.html.

4.) Add Thunderforest API Key (for Opencycle, Outdoors & Landscape Map) in index.html and uncomment the line.

5.) Upload latrine.php and index.html onto your web server. The PHP script latrine.php must be executable by the web server. The leaflet directory is obsolete as we're using downloadable leaflet from CDN (since 16.9.21)

6.) Configure Locus Map. Do not forget the key. The URL is: http:///Latrine-live/latrine.php

LocusMap

7.) Go out 👍

Sample Configuration for Mac OS X

  • Web Sharing must be enabled
  • Copy index.html to /Library/WebServer/Documents/
  • Copy latrine.php to /Library/WebServer/CGI-Executables/ and run chmod +x latrine.php
  • Default storage location in latrine.php is just fine
  • Adjust the location (URL) in index.html to var phpScript = '/cgi-bin/latrine.php';
