    5. Based on the characteristics of the geological exploring data, a method for establishing data model was presented, in which the triangle network was combined with the quadrangle network. at last, the geologic maps needed for geological research were drawn through the gdi ( graphics device interface ) and the 3d visualization system model was established for stratumtous geological body. base on the achievments mentioned above, a software system was developed which can be used independently without relying on any software platform
