Description: In order to detect the spatial con flicts that rivers dev iate from the va lleys in the process o f topog raph ic database
updating, a new a lgor ithm using the vector pro jec tion m ethod to qu ick ly extrac t the va lley lines related to the r ivers is
proposed. B ased on the algorithm, am ethod to detect the inconsistency that rivers dev iate from va lleys is advanced. The
abov e algorithm has been imp lem ented by VB6. 0+ MO, and ach ieved the better effic iency.
