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.
GPX Viewer is a simple program to visualize a GPX file. It uses libchamplain and cairo for the plot. It can show multiple GPX files, show waypoints and multiple tracks per GPX file, highlight a selected track, show a speed vs. time graph, and show distance, duration, average, moving average, max speed, moving time, and GPS points. It supports zooming, smoothing of the speed graph, and highlighting points in a speed graph on a map.
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.
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.
