摘要
考虑到当前的在线地震应急专题图制图方式存在诸如交互性差、灵活性不足和表达效果不统一等问题。研究分析了当前各类在线制图产品存在的不足之处和制图平台使用的开发技术,结合开源QGIS软件和WebGIS技术,设计并实现了在线地震应急专题制图系统。该系统提供规范的制图模板和模板管理功能,以及动态化的符号配置效果,通过清晰化的制图流程和高效的制图产出,对企业和政府在地震应急专题地图的定制和制图效率具有一定的实用意义。
Considering that the current online earthquake emergency thematic mapping methods have problems such as poor interactivity,insufficient flexibility and inconsistent expression effects. This paper studies and analyzes the current shortcomings of various online cartographic products and the development technology used in the cartographic platform,combined with open source software QGIS and WebGIS technology,designed and implemented an online earthquake emergency thematic mapping system. The system provides standardized mapping templates and template management functions,as well as dynamic symbol configuration effects. Through a clear mapping process and efficient mapping output,it has certain practical significance for enterprises and governments in the customization and mapping efficiency of earthquake emergency thematic maps.
