Method for realizing inter-mobile terminal position data interaction based on geographical information system

The related method for position data interaction among mobile terminals based on GIS, which comprises the following process: a. request process; b. positioning process; c. information return process; d. accessing the GIS process; and e. transmitting process. The client requests for positioning positively through the mobile terminal which can receive the position information form the positioning system and then transmit the information to another mobile terminal after checking and accessing the GIS system based on the position information. In this way, position information can be interacted within the mobile terminals. Since the process is launched by the terminal, and other mobile terminals can obtain the position information of the launched terminal without passing through the monitor center, ther launched mobile terminal doesn't worry to explose the trace.
