DEM高程内插
- 根据提供的10个数据点的坐标(Xn,Yn,Zn)和待求点的平面坐标(Xp,Yp),要求利用移动二次曲面拟合法,由格网点P(Xp,Yp)周围的10个已知点内插出待求格网点P的高程,编制相应的程序(According to the coordinates of the 10 data points provided by the (Xn, Yn, Zn) and to calculate the plane coordinates (Xp, Yp), using two mobile surface
DEM内插
- DEM内插就是根据参考点上的高程求出其他待定点上;(1)根据实际内插要求,解算待定点P的平面坐标(;(2)为了选取邻近的数据点,以待定点P为圆心,以;由于二次曲面系数个数为6,要求选用的数据点个数n;满足要求;vi=Ax2+Bxy+Cy2+Dx+Ey+F-Z;由n个数据点列出的误差方程为v=MX-Z;(Is inserted according to the elevation reference point for other fixed point DEM; (1) according to
