摘要

The purpose of this work is to develop a distributed interactive online geographic information system (DIO-GIS) viewer using wavelet theory. Wavelet analysis is a new mathematical tool that transforms information into a multiresolution format. This allows efficient transmission of data upon clients' requests. In DIO-GIS, a raster map is treated as a 2D function and decomposed into a nonredundant hierarchy of submaps by storing only the differences between the various resolutions. These differences in scale can be compressed, transmitted separately over the Internet, and then reconstructed up to the desired resolution by the client.
