基于FME的地形图批量分幅方法研究

地形图分幅是地形图数据生产过程中一项重要工作,包括图幅外地物裁剪、图廓整饰等工作。基于地形图批量自动分幅的目的,采用了FME数据转换处理系统与Auto CAD VBA二次开发相结合的方法,实现了自动裁切图外要素及自动图廓整饰的功能,结合了金坛地形图数据整理项目实践,结果表明该方法不仅可进行快速分幅,高效可靠,而且自动化程度很高,极大地提高了工作效率,降低了手工处理的工作量。

The Research Topographic Map Batch Subdivision Based on FME

Topographic map subdivision work is very important in the production process of the topographic map data produce,including cutting maps,maps of the border decoration work. Based on topographic map automatic batch framing purposes,using FME data conversion processing systems and AutoCAD VBA secondary development of a combination of methods to achieve the automatic cutting diagram outer contour decoration elements and automatic features, combined with terrain Jintan map data consolidation project practice,the results show that the method can be carried out quickly subdivision,efficient and reliable,and high degree of automation,greatly improved work efficiency and reduce the work-load of manual processing.
