TM/ETM+

To be added: fVEG by merging multiple TMSCAG runs populate database Karl database with file locations for Landsat 5 and 7 pre-processing function that skips when the output already exists post-processing with option for subset to be saved in specific location

Output: .mat -

   a) fsca raw - values are 0 to 1 (do I set Tom's -9999's to 0? I should use NaN)
   b) fsca - values are 0.15 to 1. Product has had the following masks applied
   c) masks 7 bands:
               1) edge mask - to deal with bands having different spatial extents (describe how this is done - see code)
               2) shadow mask (all bands < 0.10)
               3) water mask (all bands < 0.10 & NLCD indicates water) note: this isn't really necessary given the prior mask but the inverse gives us lake ice and we also know where the water isn't snow covered.
               4) "other land"  - herbaceous wetlands sometime come up as snow, this is optionally ?calculated and applied? but saved
               5) 3 band saturation mask indicating combination of saturation that result in different TMSCAG "runs"
               6) optional cloud mask (calculated for scene only applied w/ flag - rarely used)
               7) temperature mask from band 6, emissivity of snow is high using brightness temperature for now
   i) surface reflectance (6 bands)
   k) brightness temperature
   j) RGB - bands 5,4,2 (stretch version of surface reflectance)

.tif -

  a) fsca.tif (Painter et al, 2009)
  b) clouds.tif (Dozier, 1989)
  c) rgb.tif
