| Abstract: | This paper introduces reconstraction of the three dimensional terrain model from aerophotogrammetric data. The improved cubic polynomial surface is used to interpolate the network. A rapid display algorithm is suggested based on the network, thus realizing the three dimensional representation of the earth objects modeling, trees and texture. |
