摘要
文章提出一种计算DEM等高线数据的方法。通过分析等高线和DEM单元网格的关系,获得判断等高线的走向的方法,进行等高线跟踪,由此获得完整的等高线坐标序列。
This paper presents a method to calculate the contour datawithDEM. Through the analysis of the relationship between contour lines and DEM unit grid, the direction of contour lines could be determined, thus the complete contour coordinate sequencewill be obtainedby contour tracking.
