数字高程模型(Digital Elevation Model),简称DEM;(描述的是地面高程信息) 是通过有限的地形高程数据实现对地面地形的数字化模拟(即地形表面形态的数字化表达),它是用一组有序数值阵列形式表示地面高程的一种实体地面模型,是数字地形模型的一个分支,其它各种地形特征值均可由此派生。 DEM分辨率是DEM刻画地形精确程度的一...

数字高程模型(Digital Elevation Model),简称DEM。它是用一组有序数值阵列形式表示地面高程的一种实体地面模型,能够真实反映出地貌的高低起伏,一般不包含诸如树、建筑物等地表景观高度。遥感领域有另外一个相似的概念DSM(数字地表模型),是在DEM的基础上,增加了地表信息的高程,如桥梁、房屋、树木等。DEM是对地貌形态的...

Definition A Digital Elevation Model (DEM) is a digital representation of the topography of a land surface or terrain. It is a digital 3D model of the Earth's surface that captures the elevation or height of each point on the surface, as well as the slope, aspect, and other terrain ...
For the Elevation versus RMSE Elevation, the equation of the fitted model is: RMSE Elevation = 4.47393 + 0.000524928*Elevation. Since the P-value in the ANOVA table is less than 0.01, there is a statistically significant relationship between RMSE Elevation and Elevation at the 99% confidence lev...
