ArcGIS环境下的数字影像地形图产品设计与快速成图

Design and Rapid Mapping of Digital Image Topographic Map in ArcGIS

针对现有数字影像地形图产品设计架构不统一以及传统生产模式繁琐冗余的问题,设计了一种实用性强、应用范围广、生产高效的多样化数字影像地形图产品,并提出了ArcGIS环境下的批量生产与快速成图方法,保证产品多样性与现势性的同时又具备高效统一的生产流程。该方法采用开放式模板化设计,建立规则库、表达库和模板库之间的多种类和多级映射关系,通过二次开发实现了数字影像地形图的快速批量自动制图。结果表明,该产品能够有效满足不同的生产需求,开放式自动制图技术不仅大幅度提高了地图产品生产效率,还支持多样化需求。

In view of the inconsistency of product design architectures of existing digital image topographic maps and the cumbersome and redundant issues of the traditional production mode,we design a diversified digital image topographic map product with high practicality,wide application scope and high production efficiency.A mass production and rapid mapping method based on ArcGIS with an efficient and uniform production process is proposed to ensure the diversity and presentability of the product.The method adopts open template design,establishes multi-category and multi-level mapping relationships among rule base,expression base and template base.It realizes rapid batch automatic mapping of digital image topographic maps through secondary development.The results show that the product can effectively meet different production needs,and the open automatic mapping technology not only substantially improves the production efficiency of map products,but also supports diversified needs.
