Vector data compression plays an important role in the research of terrain environment simulation,integrated mapping and GIS.It is a very important task for the increase of storage capacity of mobile equipment and the improvement of transmission efficiency of vector data on network.According to dynamic programming algorithm theory,Douglas-Peucker algorithm and vector data characteristics,the paper proposes a model and improved method of vector data compression based on dynamic programming algorithm,and extends this to the case of multiple objects.Experimental results show that this method can be smaller compression errors.
