Module 2, Q7 Compare Displays



There are at 2 major differences between these displays that I notice.
1. The panchromatic has a clearer spatial resolution. The urban area in the multispectral is noticeably more blurry. The resolution is 10x10m to the multispectral's 20x20m.
2. The obvious difference of color as opposed to grayscale emphasizes the contrast between surface features, specifically the blue areas to the southeast that I'm guessing are grassland swamps. A river flows through it that appears to carry much sediment at the mouth which shows very well in the multispectral.
