With the rapid development of internet technology and geographic information technology, the research and application of GIS based on browser/server has been extended to many industries and fields, such as emergency, military, aviation, geological exploration and so on. Collaborative plotting is based on the map service published by GIS data and performs collaborative work on two-dimensional maps, but the traditional plotting systems are single-user plotting, and each user works independently, which cannot meet the requirements of multi-user collaborative plotting. Based on WebSocket data push, combined with WebGIS map service and other technologies, this paper presents a design scheme of emergency situation map collaborative plotting system. The purpose of this paper is to study and support multi-user operations such as real-time asynchronous map plotting and map editing, put forward an exclusive control mode to realize multi-user cooperative work and complete the exchange and perception of current environmental plotting information, and achieve the purpose of seamless exchange, coordination and synchronization of command decision-making, planning and deployment, so as to predict the trend of development and provide decision-making services for emergency command applications. The test results show that the method and the designed system can greatly improve the work efficiency in multi-user emergency plotting and win time for emergency command.
