| Abstract: | This paper studies the method and process of interpolating the DEM based on rectangular grid with B spline and smoothing spline. Comparing with dual linear interpolation an optimal spline algorithm is provided .Theoretical analysis and experiment indicate that the discussing methods have better effect. |
