摘要
为满足矿区对同一测区的多种不同比例尺地形图的需求,提出在计算机上实现矿山数字地形图不同比例尺间的转换方法,详细论述AutoCAD制图软件转换生成不同比例数字地形图的方法和过程,讨论AutoCAD软件生成的数字地形图到MapGIS格式地形图的转换方法,最后实现清晰准确的格式转换及比例变换。
In order to meet the needs of various different scale topographic maps of the same survey area, the conversion method among different scale digital topographic maps is presented. The methods and processes of generating different proportional digital topographic maps by AutoCAD cartographic software are discussed in detail. The conversion method from digital topographic maps generated by AutoCAD software to MapGIS format is discussed. The format conversion and scale transformation are implemented, and the results are accurate.
