This paper introduces several methods connecting contour breakpoints. On the basis of min pair of breakpoints method we present an improved method.The basic idea is: coloration for contour lines,building of spatial grid index,finding the connectpoint between two breakpoints on the basis of different color and distance, and connecting the connectpoint. The result has a higher rate of connection correctness than other methods.
