An improved method for connecting broken contour

HUANG Xuelian, HU Peng,BAI Yiduo (School of Resource & Environment Science, Wuhan University, 129 Luoyu Road, Wuhan 430079, China )  
This paper introduces several methods connecting contour breakpoints. On the basis of min pair of breakpoints method we present an improved method.The basic idea is: coloration for contour lines,building of spatial grid index,finding the connectpoint between two breakpoints on the basis of different color and distance, and connecting the connectpoint. The result has a higher rate of connection correctness than other methods.
