| Abstract: | In order to substantially accelerate the process of intersection finding using vector
data in GIS and CAC. this paper puts forward a new method. namely. Raster Detection
plus Vector Calculation. On the basis of analysing the reasons of defects by the pure
vector mode intersection finding. this paper not only describes the principle of this method.
introduces corresponding data structure and algorithm. but also demonstrates the prelimi-
nary experiment results and the further analysis on this method. |
