【摘要】 提出一种基于等高线建立规则格网数字高程模型的方法。该方法考虑了原等高线的数值特征和几何特征，因而具有较好的稳定性和可靠性。还提出了对于所建立的数字高程模型可信性的两种验证手段：解析曲面比较和等高线还原对比。更多还原

【Abstract】 In this paper a method for establishing a gridded DEM from contours is discribed.The method takes into consideration the numerical and geometrical characteristics of contours,and therefore has better stability and reliability.Two methods are proposed to measure the reliability of the established DEM:comparison of the analytical surfaces and the restoration contours.更多还原
