| Abstract: | Three-dimensional GIS is more and more extensively used in the modeling and analyzing of geological bodies.It has the advantages of intuition,real and powerful analysis functions.The High-Cutting Slope is a special kind of geological body,which has its own characteristics and is necessary to be modeled in an integrated way.It is appropriate and efficient to develop a visualized and aided analysis system of the high-cutting slopes using the 3D GIS.By studying the 3D visualized modeling algorithms,we noticed ... |
