基于PostGIS的历史航迹重演分析系统设计与开发

摘要

针对当前航迹数据的存储管理与分析计算技术不成熟 、没有一套完善的历史航迹数据存储 、管理 、重演与分析工具的现状,首先设计了基于PostGIS数据库的历史航迹重演分析系统架构,并建立了该系统的具体功能模块;然后,采用C#编程语言和SharpMap地图渲染引擎对系统的原始数据存储 、航迹重构 、航迹时空查询 、重演与显示等模块进行了开发实现,验证了该系统架构的灵活性 、易用性和可扩展性.%The present technologies on trajectory data storing ,managing and analyzing are immature , and there is no good software for storing ,managing ,replaying and analyzing the existing historical trajectory data .In order to solve these problems ,a framework of the historical trajectory replay and a-nalysis system is established based on PostGIS database ,and specific function modules are designed . These modules of the framework ,including raw data storing ,trajectory rebuilding ,trajectory spatio-temporal querying ,and trajectory replaying are developed by using C # and SharpMap engine .The de-veloped system verifies the flexibility ,usability and good expansibility of the presented framework .
