基于卫星导航与时空实体实现船舶轨迹分析系统
Ship trajectory analysis system based on satellite navigation and spatio-temporal entity
摘要
Abstract
Based on satellite navigation,spatio-temporal entities,web geographic information system(WebGIS),spatial databases,etc.,key information on ship attributes,real-time positions,historical paths,associated relationships,and operating statuses has been extracted,leading to the construction of ship entity resources and the establishment of a ship trajectory analysis system.The system provides functions such as map services,trajectory data management,trajectory visual query display,trajectory spatio-temporal analysis display and analysis model parameter configuration.It enables management and analysis of multi-source,multi-temporal and diversified ship trajectory data,presenting ship element characteristics and analysis results,increasing information value density,and enhancing query and analytic abilities.Thus,it enhances the efficiency and accuracy of ship trajectory analysis,serving as a more effective support for ship trajectory analysis business and related applications.关键词
