TM/ETM+

To be added: 1)fVEG by merging multiple TMSCAG runs (write matlab function) 2)use emissivity for each landcover type to determine actual temperature instead of brightness temperature 3)post-processing with option for subset to be saved in specific location 4)populate database Karl database with file locations for Landsat 5 and 7 5)pre-processing function that skips when the output already exists

Output 1: .mat - 

   1) fsca raw - values are 0 to 1 and NaN (-9999 from TMSCAG, 0 for TMSCAG<0)
   2) fsca - values are 0 and 0.15 to 1 and NaN from above. Product has had the following masks applied as NaNs
   3) masks 7 bands:
               1) edge mask - to deal with bands having different spatial extents
                  a) NLDAS processing did a similar thing. All output from USGS is currently not trimming the edges. See current [1]
               2) "other land"  - always applied for 0 and 127 - optionally calculated and applied: herbaceous wetlands or other classes
               3) shadow mask (all bands < 0.10)
               4) temperature mask (if fsca>0.15, emissivity is 0.98, otherwise ASTER emissivity set used
               5) water mask (all bands < 0.10 & NLCD indicates water) - this is a subset of 2...inverse is snow covered lake
               6) optional cloud mask (calculated for scene only applied w/ flag - rarely used)
               7) fsca < 0.15
               
   5) snow covered lake (NLCD=Water,fSCA>0.15
   5) RGB - bands 5,4,2 (stretch version of surface reflectance)
   6) surface reflectance (6 bands)
   7) brightness temperature
   9) ndsi - (2-5)/(2+5)
   10) 3 band saturation mask indicating combination of saturation that resulted in different TMSCAG "runs"
   11) geoinfo from geotiffinfo on original file 
   12) structure of pr, dateS, utmZone
