摘要
船舶数据的管理和可视化对航道、船舶管理具有重要意义。大量快速更新的船舶位置信息和影像数据,对数据存储、检索以及可视化提出了较高的要求。本文结合实际应用需求,基于非关系型数据库MongoDB和开源地图API设计并开发船舶信息管理系统。该系统将船舶和热点区域数据存储在MongoDB中,可在浏览器中高效同步显示大量空间数据,提供属性查询、空间检索和统计制图等功能,并且可在线编辑数据库中的热点区域数据。本系统主要解决了MongoDB数据库中空间数据高效检索,BSON文档格式和Geo JSON地理要素格式的转换,数据库中空间数据在线编辑等问题,为船舶信息化管理提供了支持。
Ship data management and visualization are important parts in the field of channel management,ship management and soon. Massive and rapid updating ship data and image data makes it more challenging to manage and visualize the data. In this paper,a geographic information system for displaying and managing ships is developed based on MongoDB and OpenLayers. The ship data and the hot place data stored in MongoDB can be efficiently displayed in browser. Multi- criteria query,spatial query for ship,generating statistical chart and editing database online are all implemented in this system. Efficient spatial query in MongoDB,Converting BSON document to Geo JSON format and online editing have been solved in this paper. It is hoped that this system could provide support for ship management.
