Spectrаl vegetаtiоn indices (SVI’s) аre mathematical manipulatiоns оf wavelength layers used to depict specific information regarding vegetation “greenness” from an image. SVI’s can be used to determine seasonality and changes in vegetation health and vigor over time; they can also be used to develop models used to estimate biophysical variables such as fPAR, biomass, and leaf area index. a.  List the two common SVI’s discussed in class and write the equation for each.              SVI #1:                                                     SVI #2:        b. If you were to compare values between two images acquired at different times of the year or from different places, which SVI should you use and WHY?                c. Assume the image below is one of the SVI’s you listed above:               Which area on the image has a moderate amount of green vegetation? ___             Which area on the image has a lot of green vegetation? ____                    Which area on the image has no green vegetation? ___
