This is an image of South East Bali courtesy of the Landsat 7 satellite using bands 3,4, and 5, which shows that area in inferred color. Infrared displays landscapes in colors we cannot see in the visible, showing the different surface types. The infrared bands are useful to our research because it clearly displays our areas of interest, such as rivers and bodies of water.
Above is the same image categorized into specific land types. Land types are broadly described by a color. The image above is compromised due to distortion from cloud interference, but the colors help classify areas of interest. For example, blue and green represent water (st varying depths), while pink and maroon areas are clouds (unfortunately), barren or covered areas.

Comparing the images of Southern Bali from 1997 and 2010, there is a significant difference between development in the tourist center of Kuta & over populated cities like the capital, Denpasar. The amount of vegetation in the image taken in 2010 is noticeably lesser in the image taken in 1997. The loss of vegetation due to an increase in urbanization indicates an increasing population and pollution production.
