  1. NDVI Normalized difference vegetation index Band Ratios in Remote Sensing KEY REFERENCE: Kidwell, K.B., 1990, Global Vegetation Index User's Guide, U.S. Department of Commerce/National Oceanic and Atmospheric Administration/National Environmental Satellite Data and Information Service/National Climatic Data Center/Satellite Data Services Division.

  2. First: A few Simple Reminders about Spectral Signatures Thanks to Robin Weeks

  3. Laboratory Spectral Signatures IICommon Urban Materials Healthy grass Concrete Astroturf wavelength Thanks to Robin Weeks

  4. The Effect of the Atmosphere on Spectral Data Path Radiance (Lp) Atmospheric Transmissivity (T) Thanks to Robin Weeks

  5. Effect of Topography on Scatterplots Grassy fields Flat terrain Terrain without topography Water/ shade Bare ground Terrain with topography Thanks to Robin Weeks

  6. Vegetation:Pigment in Plant Leaves (Chlorophyll) strongly absorbs visible light (0.4 to 0.7 μm)Cell Structure however strongly reflects Near-IR (0.7 – 1.1 μm) Thanks to Robin Weeks
