| Abstract: | For meeting the practical requirement,on the base of the analysis of error causes related to scanned topographic map,the common methods for map correction are introduced,and one error correction method which integrates zone strategy and cubic convolution is propsed.The case study showed that the proposed method was prior to the single cubic convolution method,and its result met the requirements. |
