Mod 2


The use of the multi-spectral image allows quick and easy distinction between vegetation, water and urban areas. The blue vegetation appears to be plant growth on islands in the southern half of the image. In the northern half, there appears to be blue vegetation growth in urban parks or backyards. If you were looking to obtain sites for urban areas, the panchromatic image may be better as they stand out. You would have to be careful when using the images for making boundaries, though, as the sand in the panchromatic also appears very light in color. This could make beach-front residence difficult to determine.
