lEO, THANK YOU! Follow your instruction, I believe I get it. The mosaic wizard is the greatest function that other softwares do not have. I make a "project" folder in which there are three folders : c:ER Mapper\project\p128-45 and \p128-46, \128-47. Accordingly, I save each image into the same folder "ers" as p128_45_2_1_1993.ers and p128_46.., p128_47 .ers. After I have done all three images, I click on the mosaic wizard, load p128_45_2_1_1993.ers, keep the same default, click greyscale, finish. Image display in greyscale, I open algorithm window, It shows there are three layers. I click "surface" and change to RGB, a color image displays. However, the display window only displays 2 image, a gap in between. I turn on and turn off the layer to determine which one is not being mosaiked. I find p128_45 is missing (when I click greyscale in mosaic window, a dialog quickly displays what is being mosaic, I see rejecting... and mosaicing...) Probably one of the row is not correct. Thanks again. It works! Have a wonderful weekend. May I call you from time to time to learn more from you.
