    • Abstract
  • Using spatial autocorrelation analysis,the digital elevation error is studied;and the results show that there is no significant global spatial autocorrelation of digital elevation error in all cells,the spatial pattern of digital elevation error is random on the whole.There is significant local spatial autocorrelation between one cell and its neighbors,and the difference of digital elevation error between one cell and another is small,the spatial pattern of digital elevation error converges strongly in local areas.
