摘　　要：在AutoCAD地形图制图过程尤其是在航测地形图制图过程中,经常会出现高程点与等高线不符合的地方。本文通过对地形图中高程点等高线错误矛盾的分析和以前检测方法的研究,提出了一种能全面检查又相对快捷的检测方法,并在AutoCAD平台下运用.NET的方法实现了该算法,通过对比和分析可知,完全达到预期效果。In the process of AutoCAD topographic mapping, especially in the process of aerial topographic mapping, there are often inconsistencies between elevation points and contour lines. Through the analysis of the error contradictions between elevation points and contour lines in topographic maps and the study of previous detection methods, this paper puts forward a relatively fast and comprehensive detection method, which is applied in the platform of AutoCAD.NET. The algorithm is implemented by the method. Through comparison and analysis, the expected results are achieved.
