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
