采样误差

The computer simulated sampling points with different grid cell sizes were generated and then interpolated into 10000 points with inverse distance weighted. Finally, the original value was compared with the interpolated value for the same grid cell to find the sampling error, and optimal sampling points were determined according to the allowable sampling error.
