基于MapGIS K9的林业地图符号库构建及符号化实施（英文）

为提高林业地图的制图效率和智能化水平,笔者提出了基于MapGIS K9平台的林业地图符号化方案。首先按照国家林业局2010年10月颁布的《林业地图图式》构建林业地图符号库,然后建立符号配置规则库以实现数字环境下符号配置规则的表达,最后在MapGIS Objects组件开发技术支持下实现了符号化模块,按照符号配置规则对林业专题数据进行可视化表达。实践证明该方案能够基本满足包括森林资源规划设计调查成果图在内的常见林业地图制图要求。

Construction of Forestry Map Symbol Library and Symbolization Execution Based on MapGIS K9

In order to improve the cartography efficiency and the intelligent level of forestry map,we put forward the symbolization scheme of forestry map based on MapGIS K9 platform.Firstly,the symbol library of forestry map was constructed according to The Graphic Representation of Forestry Map which was issued by the National Forestry Bureau in October,2010.Then,the symbol configuration rule database was established to realize the expression of symbol configuration rule in the digital environment.Finally,the symbolization module was realized with the support of MapGIS Objects component development technology,and the thematic data of forestry were visualized according to the symbol configuration rule.The practice proved that the scheme could basically satisfy the cartography requirements of common forestry maps which included the forest management inventory map.
