Abstract
Generally, feature of real world as 2-dimensional information of point, line and polygon achieve a GIS function from 2-dimensional GIS. But at enduring the geography elements which exist when it is composed of 3-dimensional spatial information it is abstracted with 2-dimensional which will reach, the loss of many information and 2-dimensional GIS of existing the basic limit exists md, Accordingly, 3-dimensional geography elements of the real world even at the computer controlling with 3-dimensional geography element original it will be able to minimize the loss of information which it keeps, for 3-dimensional expression and the analysis against the natural facility and the artificial facility of the real world it is the actual condition whose 3-dimensional GIS of ultimate form are necessary. This study was 2-dimensional feature a point the line and polygon and 3-dimensional spatial data information as the method for to use the VRML(Virtual Reality Modeling Language), 3-dimensional virtual worlds for 3-dimensional GIS applications to create and hereafter various decision making of at connection web more efficient and the possibility of doing in vision in order to be, it drew up a spatial database.
