　　In order to solve problems exist in spatial data watermarking technique with rapid expansion,this study aims to develop a watermarking system of vector maps that is based on spatial relationship.It hides the information into spatial topological relation and areas.This system also integrates different types of attacking algorithm and visual analyzing system for map data.The experimental test gives consideration to both theory and practice as well as innovation and function; meanwhile,it takes an important step in area of spatial data security and further industrialization.
