In this case study, you will learn how remote sensing can aid in the monitoring of tropical rainforests, such as the Amazon rainforest. You will see how this forest disappeared over a period of 30 years, and how the rate of deforestation can be measured. You will also learn that, even in deforested areas, the process of vegetation growth still goes on.

The satellite sensor you will be working with is Landsat TM. The exercise will be done using the LEOWorks image processing software.
