This project aims is providing wireless access to the Google Earth system through the
mobile phone of the user. It is designed to operate in the railway and bus stations. This device is
provided with an LCD where the Google earth map is displayed and this map can zoomed and
can be moved in different directions so that the passenger can make use of the map from his
normal mobile which need not require any GPRS facility. It also makes the user independent and
need not depend on any person to know about the direction in which he has to reach the
destination.
In this project we make use of the PC with internet connectivity. This PC displays the
Google earth map on its LCD. When ever the passenger needs to find the path to his location he
has to call to a predefined mobile number which is interfaced with the PC. The passenger can
make use of the number pad of his mobile to drag and zoom the map in different directions.
The microcontroller is the heart of the entire project. It provides an interfacing between
the mobile and the computer. The mobile connected to the microcontroller is enabled with
automatic call answer option. The controller receives gets the commands from the mobile with
the DTMF tones and provides the same information to the computer using serial communication.
There will be a software application at the PC end which process the information received from
the controller and performs the corresponding functions.
Features:
1. Wireless access to Google Earth map.
2. User friendly operation.
3. Map navigation can be done from the mobile.
