摘　　要：研究在不规则曲面上基于规则格网进行等值线的生成方法,提出解决等值线二义性及非闭合等值线绘制的处理方法,最后基于Mapxtreme技术实现规则格网的等值线绘制。有效解决了绘制的等值线的二义性问题和非闭合等值线绘制的处理问题,将该方法应用于实际领域所绘制的等值线在效率和效果方面都取得了令人满意的效果。We focused on the generation method of isoline on irregular surface based on regular grid in this study. An efficient resolution to isoline ambiguity and drawing of non-closed contour was proposed. An implementation of the resolution based on Mapxtreme technique was also introduced to draw the regular grid isoline in fieldwork application, which had satisfactory efficiency and performance.
