Analysis on high fidelity of the DEM

The problem of DEM the artificial high-fidelity model is to maintain a realistic three-dimensional or three-dimensional data with the original in its conflict-free region adjacent to the three-dimensional characteristics and elevation logic.Between adjacent contour corresponding to the actual height of the partition area can be monotonous for a continuous surface connection of the surface,making high-fidelity characteristics of the actual elevation in this zone is set up.High-fidelity characteristics of the DEM ensure that the process of forming height is still high,lower low is still to ensure that the Department of the flow line elevation sequence,and to maintain the substance of the original data sequence of ups and downs of the terrain.
