July 27: Week Four?!

Today I met with Dr. Vodacek in order to ask some questions on how to do analysis of fire burns over time.  He suggested that to start, I should choose four images from four decades (1980s-present) that were taken before fires and compare them to each other in order to note change over time. He also gave me a paper to read about SAVI and MSAVI so that I will know how to calculate this index in ENVI; he also helped me by explaining different strategies which will help me to check if I have built and applied a mask correctly.  I spent the remainder of the day reading the article and will start looking for the four images tomorrow.
