基于ArcGIS的地形图制作关键技术分析

The Key Technical Analysis Based on ArcGIS Topographic Map Production

文章通过对ArcGIS制作基本比例尺地形图流程的研究，分析利用ArcGIS制作基本比例尺地形图的一些关键技术及相关特点，如制图前期坐标系统的定制、符号库的制作、数据拓扑检查等工作，以及地图要素符号化时的要素标注、制图表达等技术的运用。其目的通过这些关键技术及方法解决基于ArcGIS的地形图制作的难点问题，使之符合我国地形图制作规范。

By the production process of basic scale topographic maps for ArcGIS it analyze the ArcGIS production scale topographic maps, some of the key technologies and related features, such as mapping the early custom of the coordinate system, the production of symbol libraries, data topology check work map elements of the symbolic elements of labeling and the representations the use of technology. The purpose of these key technologies and methods is to solve difficult problems in the production of topographic maps based on ArcGIS, with to make suer our topographic map production specifications.
