Remote sensing offers an efficient way to estimate vegetation properties over large geographic areas. You can use spectral vegetation indices (VIs) calculated in ENVI to analyze vegetation properties. This requires the following:

  1. An understanding of the structure and function of vegetation and its reflectance properties.
  2. An understanding of the vegetation properties that you can estimate by calculating VIs on hyperspectral reflectance data, and knowledge of how these VIs work.
  3. Using ENVI to calculate applicable VIs and analyzing the output to determine the vegetation conditions in your data.
  4. Applying classifications to the various ecologies of the indices and analyzing the classifications for specific conditions, such as agricultural stress, fire fuel distribution, and overall forest health.
