林业专题制图分幅技术的研究与实现

对林业专题图制作中的分幅技术进行了分析研究,详细介绍了林业专题制图模块的工作流程,运用软件工程中的MVC设计模式将专题图制作的数据和样式分离,各类专题图样式统一用样式模板控制,不同的分幅方式统一用分割模板控制,并将其应用在县级森林资源管理信息系统的林业专题制图模块中,实现了专题类型和分幅方式的灵活定制。

Study and Realization of Forestry Thematic Mapping Framing Technique

The technology of forestry thematic mapping framing was analyzed and studied in the paper,and the workflow of forestry thematic mapping module had been introduced in detail.Moreover,through using the MVC design patterns in software engineering,the data and style were separated from thematic mapping,using map style model control thematic map style uniformly and using segmentation templates control map division uniformly,and the module of forestry resource thematic mapping was applied in county-level forestry resource information system and the flexible customization of thematic type and map division was realized.
