The image(1) upper left is multispectral and the image(2) lower right is panchromatic. The primary difference is color - one is in RGB 4-3-2 and the other is in black & white 1-1-1. The resolution is different, probable 30m vs. 15m. The spatial pattern is also different. Image(1) shows vegetation islands in red and
clearly defined water bodies in blue. In Image(2), islands looked like water bodies.
