Dear readers,
Another proof-of-concept I've made is about realtime monitoring a device (or person) via a web-interface. To achieve this I've made a simple (event driven) client application that sends GPS coordinates to a server. Serverside I've written a J2SE server that receives and parses the GPS coordinates and a PHP-script that shows the current (and recent) location of the user on the map using Google Maps as supplier of the mapdata. A few months later I have updated the software with a login-feature so I was multiple user capable and published it online. I haven't been doing any PR on this project, but the number of users kept on growing. In the attached screenshot you can see the active users!
If you want to try the software just visit this site. If you want a realtime tracking system included in your own solution, just contact us!
