| Abstract: | Multi_resolution real_time modeling and rambling on topography surface has an important application in GIS, but it is a difficult problem in algorithm design. The modeling features of B_Spline curve and surface fitting are studied,and B_Spline wavelet also. This paper realizes automated multi_resolution modeling on DEM (Digital Elevation Model) topography surface by combining non_uniform B_Spline surface fitting with quasi_uniform B_Spline"wavelet multi_scale effectively. The proposed approach in the article is applied to the slope DEM simulation of one constructing expressway located in mountains. The resulting simulation shows that the modeling is realistic and resolution is visible. |
| Keywords: | multi-resolution modeling on DEM topography surface construction non-uniform B-spline wavelet |
