Research on sensor data visualization method based on real-time dynamic symbol

Geographic information system has been widely used in sensor device management. The sensor was abstracted into the map symbol and displayed on the map. while it is difficult to realize the real-time data visualization in the GIS visualization process, this paper studied the design method of the real-time dynamic map symbol, applying the communication protocol to the process of modeling and visualization of the map symbol. this study builds data model of real-time dynamic map symbol from two aspects(data communication protocol, visualization), and put forwards the combining method of the communication protocol, dynamic symbol real-time sensor data visualization in the GIS environment. so as to realize the sensor data visualization based on the real-time dynamic map symbol.
