基于开源QGIS平台的地图符号设计实现研究

Research on Map Symbol Design and Implementation Based on Open Source QGIS Platform

针对开源QGIS平台缺少相关专业制图符号无法满足测绘专业领域使用需求的问题,提出了一种基于开源QGIS平台的地图符号设计实现方法,即通过平台自带的样式管理器实现和通过第三方矢量设计工具辅助平台进行符号设计,以满足复杂应用场景下地图符号设计应用需要。基于开源QGIS平台的地图符号设计方法可以节约测绘领域企事业单位的运营成本,在商业地理信息系统(Geographic Information System,GIS)平台之外为社会企事业单位提供开源替代解决方案,同时有利于开源GIS平台的推广使用及促进开源事业的发展。

In response to the issue of the lack of relevant professional mapping symbols on the open-source QGIS platform,which cannot meet the usage needs of the surveying and mapping field,this article proposes a map symbol design and implementation method based on the open-source QGIS platform.There are two ways to implement this technology,one is through the platform's built-in style manager,and the other is through third-party vector design tools to assist the platform in symbol design,which meets the needs of map symbol design applications in complex application scenarios.The map symbol design method based on the open-source QGIS platform can save the operating costs of enterprises and institutions in the surveying and mapping field,provide open-source alternative solutions for social enterprises and institutions outside of commercial Geographic Information System(GIS)platforms,and facilitate the promotion and use of open-source GIS platforms and promote the development of the open-source industry.
