| Abstract: | This paper, taking forest pest investigation system in fields for example, introduces how PDA realizes the real-time data transmission between the terminal and the server with the wireless network. Accordingly, it can apply for the free map services provided by Google map as survey map in field data collection. Meanwhile, it reduces the pressure of PDA storage space. This method can join data collecting with data processing together and improve the development efficiency and scope of applieation of PDA system. |
