Digital maps can be stored and distributed electronically using compressed raster image formats. In this paper, we evaluate the most suitable compression methods for storing digital map images. We apply the latest compression standards for binary images (G4, JBIG2), and the standards for computer graphics with limited number of color tones (GIF, PING). Experimental results are given for two sets of clean noiseless map images generated from digital map database, and for one set of noisy images.
