中比例尺地形图数字化方法研究

Research on Digitizing Method of Medium Scale Topographic Map

针对1∶5000和1∶10000比例尺地形图地形、地物要素的类型、特点、分类编码、图式符号、数字化方法、开发技术等问题进行了深入的研究,探索在AutoCAD平台下开发中比例尺地形图数字化软件,实现中比例尺地形图的定位、数据编辑、交互及批量符号化处理、自动绘制格网图廓等工作,实践证明该方法具有操作简便、地物符号齐全、图形美观、规范,实用性强等特点。

This paper deeply discussed the terrain, feature type, characteristic, classification coding, cartographic symbol, digitizing method and development technique for 1 ： 5 000 and 1 ： 10 000 topographic map. It probed into the development of digitizing software for medium scale topographic map based on AutoCAD platform. It realized the positioning, data compilation, batch symbol processing, and automatic drawing of grid and map border for medium scale topographic map. It proved that the method has the characteristics of convenience for operation, complete feature symbols, beautiful figure, standard, and better practicability etc.
