基于MAPGIS的地形图数字化研究

Study on digitalization of topographic map based on MAPGIS

随着计算机科学技术的不断发展,测绘行业中地形图较之以前的手工制图有了很大的发展。由中国地质大学(武汉)研制开发的MAPGIS软件具有强大的图形编辑和图形处理功能,是测绘行业中常用的数字制图工具,提高了测绘工作的效率。本文介绍了MAPGIS在地形图镶嵌配准、矢量化、误差校正等数字化制图的技巧和方法。

With the continuous development of computer science and technology, the drawing method of topographic mapping has made a greater development comparing with the previous hand-drawing in the surveying and mapping industry. The common software for digital mapping named MAPGIS is developed by the China University of Geosciences(CUG-Wuhan), and has the great graphic editing and processing functions to improve work efficiency. The paper introduces the methods and skills of topographic digital mapping with MAPGIS, such as mosaic, registration, vectorization and error correction, etc.
