Abstract

This paper proposes a new data structure for GIS image data (wavelet pyramid structure) based on integer wavelet transform. With this structure, an original image is divided into an image of the lowest resolution and two groups of image detail coefficients. These coefficients are organized by a pyramid structure-wavelet pyramid structure. In comparison with R-trees, this structure can reduce data redundance and the original image can be restored perfectly and losslessly with this method.
