To be added: set Tom's -9999's to NaN (-9999 might be set in TMSCAG IDL script 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 1: .mat -
a) fsca raw - values are 0 to 1 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)
Output 2: .tif -
a) fsca.tif (Painter et al, 2009) b) clouds.tif (Dozier, 1989) c) rgb.tif
