Abstract
Recently, the necessity of using spatial information for web-based and mobile applications has been rapidly increasing. However, there are two challenges against the publication of spatial information. The first one is efficient data transmission, which is both large and complex, through a slow wireless communication link. The second one is how to provide the resultant adapted data for varied and heterogeneous clients. This paper proposes a new transmission method, namely, the Scale-Dependent Transmission method, with the purpose of improving the efficiency of vector spatial data transmission across the Internet. Its main idea is “Transmit what can be seen”. Scale is regarded as a factor naturally associated with spatial features so that not all features are visible to users at a certain scale. Additionally, the paper proposes Wavelet-based map generalization algorithm, which achieves O(n) time complexity and adapts data to fit the needs of varying clients. Experiments show that the response times of individual operations were substantially reduced when using the proposed method.
