GPS Visualizer is an app to convert your GPS Route Track log/data in NMEA/GPX format and display it on Google Map and Google Earth formats. We have built this app as a part of our project in which we have built a GPS based vehicle track logger. Our GPS logger is based on a Arduino Uno microcontroller board with an Arduino GPS shield from ITEAd studio . The GPS shield has an SD card interface which supports storage of standard GPS signals in NMEA format to be stored and saved on text file in microSD card. The text file then can be uploaded using this app and then the app will convert that text format NMEA codes into proper Google Map GUI interface.
