Research on ship dynamic map based on AIS

With the development of cloud computing, big data and other technologies, WebGIS has been widely used as an effective tool for processing and analyzing spatial data. AIS data covers the core elements of ship navigation, and its visualization can track the ship trajectory and count the traffic density. For effectively analyzing AIS data, this paper designs and implements a web ship dynamic map system based on AIS data. This system consists of data layer, data service layer, business logic layer and presentation layer. Data layer realizes data storage through big data technology and relational database. The data service layer provides data through GeoServer and Spring Dao technology. The business logic layer realizes business logic through Spring Boot, which converts the data into JSON format and provides it to the presentation layer. The presentation layer realizes map display through Openlayers. Practice shows that the system can meet the requirements of real-time display and has high scalability.
