Aiming at the problem of one-to-many matching for multi-scale facet element,this paper presents multi-scale area entity shape matching based on tangent space method.It searches the candidate matching set by expanding the buffer zone outside the source polygon,combines the area patterns in the candidate matching assemble,matches the new polygon shape with the original polygon shape after combining the area patterns,and gets the best matching set.Experimental results show that computational process of the method is simple and easy to implement,and it has better matching efficiency.
