Google Map GPS Cell Phone Tracker allows you to track Android, iOS, Windows Phone, and Java ME cellphones using Google Maps. It has two parts, a server and phone clients. You have a choice of two servers, using asp.net and SQL server or PHP and MySQL. The server software allows you to view cellphone locations in realtime using Google Maps and store routes and view them later. The client applications send their locations to the website periodically. All four applications work properly in the background and are written natively on each platform.
MyGeoTrails allows you to mark places of interest on the map along the trail created by the app and share them on Facebook if you wish. You may even share the complete trail with the click of a button. Use retrace mode to travel back on a trail already created before. The app records your GPS locations periodically when you press the start trail button. The information is stored only in your phone. When you explicitly share your trail information, only then is the information moved around on the Internet.
O2OO reads sensor data from a car into a sqlite database and generates graphs of the data so you can analyze the behavior of the car. It can also retrieve the location from a GPS module and store it in the same database, then can create a Google Maps KML-file, coloring the route line with a color depending on a sensor reading.
LocDemo demonstrates the functionality of libwlocate. After startup, it evaluates the current geographic position of the user and displays it within a map. This solution offers geographic localization that works without the use of GPS and without submitting tracking or position data to commercial providers of such services.
phpMyGPX is a Web application based on PHP, MySQL, and OpenLayers to manage photos and GPX files with a browser, on your local machine or online, to share your tracks and images. GPX is an XML file format containing track points and routes collected by GPS receivers, and is very popular with navigation, geocaching, and OpenStreetMap.
