A new method of automatic creation of topological relation between contours by constructing the\n“topologic contain binary tree”is discussed in this paper

and based on the binary tree data structure a fast color fill application is proposed to commendably realize the vector effect of contour color fill graph in random scale

random height interval

random boundaries surroundings.From the relationship between boundary lines and contours

the topologic relation among contours can be built and stored in the tree structure.Such a topologic structure displays the linking and closing between boundary lines and unclosed contours

the nesting among closed contours in the order of tree rings.It is successfully applied in visualization and automatically mapping of submarine topographic data observed by multibeam

and it overcomes the insufficiency of contour mapping produced by common algorithm

especially conquers the inconsistency between color blocks and contours produced by mapping software for multibeam postprocessing.
