Getting Started with ArcMap"The Amazon rainforest spans nine countries and millions of square kilometers, making it the largest tropical rainforest in the world. Since the 1960s, the rainforest has undergone immense deforestation. Current estimates indicate only about 80 percent of the original rainforest remains.
One of the most deforested regions is the Brazilian state of Rondônia. In 2011, a Brazilian judge prohibited the construction of a road that would have traveled through a large stretch of protected land in Rondônia, potentially causing even more deforestation.
In this project, you'll use ArcMap to estimate how much deforestation was prevented by prohibiting a proposed road. First, you'll find the study area. Then, you'll compare roads and deforestation to determine the pattern of existing deforestation, before applying your findings to the proposed road. Finally, you'll communicate the results to others by designing a map." [from learn.arcgis.com]
