Efficient Compression of Vector Data Map Based on Clustering Model

This paper proposes a method for the compression of vector data map basedon a clustering model.The proposed compression method was implemented and applied to compress vector data map to investigate its performance in terms of the compression ratio,distortions of geometric shapes.The results show that the proposed method provides a feasible and efficient solution for the compression of vector data map and is able to achieve a promising ratio of compression and maintain the main shape characteristics of the spatial objects within the compressed vector data map.
