沉船之类的沉物数据因为其对航行安全的威胁,是海图图面反映的重要水上要素。本文通过分析国内外现状,探讨建立沉船等沉物的管理机制,及建立沉船沉物数据库的必要性,并对基于WebGIS架构的沉船库的系统流程、数据库设计、功能实现等进行分析设计,以WebGIS的形式将沉船沉物数据在浏览器中发布,保证数据的准确性和惟一性,提供航海用户查询使用。
Sediment data such as wrecks, because of their threat to navigation safety, are important waterborne elements reflected in the chart. Based on the analysis of the current situation both at home and abroad, this paper discusses the establishment of the management mechanism of sunken shipwreck and the necessity of establishing the shipwreck sunken object database, and analyzes and designs the system flow, database design and function realization of sunken shiphouse based on WebGIS. In the form of WebGIS, shipwreck sediment data will be released in the browser to ensure the accuracy and uniqueness of the data and provide navigation users with queries.
