Abstract. Real-Time Monitoring System(RTMS) is the result of the development of information technology, which has made a huge difference to the life and work. The Android based GIS terminal is designed and implemented for RTMS, integrated with Internet communication, GPS, and intelligent navigation technology. The GPS module is used to collect positioning information of the terminal. Utilizing the cloud computing, the design gives a real-time route guidance to improve efficiency of traditional GPS navigation. With the Internet technology, this paper could complete geographic information uploading function. Based on Android application development technology, the paper designs the terminal software to complete monitoring function. By using the Android software designed in this paper, the GIS terminal can realize positioning and navigation features, upload monitoring information to the back-end system. And the test result proves that the design of the application development can meet the expected functional requirements of the RTMS.
