| 摘 要： | DEM高保真问题指人工模型是否保持了有实际三维空间或原始三维数据所具有的在其相邻区域的无冲突的三维特征和高程逻辑.在相邻等高线间所对应各实际高程地带均可剖分为连续的各单调坡面的连接曲面,使得高保真特性在这个实际高程地带内是成立的.高保真特性保证了DEM形成过程中高处仍高、低处仍低的特性,保证了汇水流线的高程序列;实质是...

| Abstract: | 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... |
