| Abstract: | In process of real-time 3D terrain-data acquisition based on PDA, the communication program was programmed with windows CE API function, serial interface operation combined event-driven with asynchronous-driven was adopted in communication port. It may realize not only real-time obtain GIS data, real-time paint map and real-time note attribute of map but also automatic build graphics via terrain-data acquisition module based on PDA and communication between PDA and mapping apparatus. |
