海域使用立体分层数据模型构建与应用OA

Marine stereotactic space management is an effective way to optimize ocean space and improve the utilization efficiency of marine resources.Purpose of the study is to set up digital and automatic management of the stereo right to use marine.Using survey data,planning data and management data from the National Maritime Dynamic Surveillance Monitoring Database,the study analyzed the data features of the three-dimensional layered sea use.The entity data model is used to transform the two-dimensional vector ownership data into a three-dimensional model.According to the technical route of ontology construction,data correlation and analysis application,the data model was built to study the maritime stereotactic space,which was ap-plied to developing the 3D visualization application system.In terms of consistency,readability,flexibility,efficiency and so on,the three-dimensional data model meets the application require-ments,which is superior to the traditional two-dimensional data model.Employing the Cesium 3D engine,the major function of the system is the spatial analysis and synthetic statistics of the stereo right to use marine.The data model and application system have supported the up-front exploration of the management and decision on the right to use maritime stereotactic space.It has been effectively applied in Guangdong Province.
