Compressing multi-component digital maps using JBIG2

Digital maps can be stored and, distributed electronically using compressed raster image formats. In this work, we study how the latest JBIG2 standard can be used for storing the map images. Image tiling must be performed to support direct access to partial images in the compressed file. This can be implemented by storing each image block as its own segment. Another problem is how to store the multiple image components. There are altemative ways to solve this problem by utilizing the features of JBIG2 in creative ways.
