This is our biggest pretty image as of 8/29/2000. It is 14535 by 11946 30-meter pixels, considerably more detailed than the gif file that you see. The data is stored in the UTM zone 10 projection, so integrating information east of 120 would be difficult.
A Tif file of this image is 12 inches high and is recorded at 200 dpi. It unzips from 8345169 bytes to 14092572 bytes. The saturation seems to have dropped in the creation of the tiff file.
