This is a cross-post from the GIS StackExchange because it gained no traction there.
I have 15 multiband rasters for a total of 45 single-band images (5 dates x 3 sensors x 3 bands per sensor for which I need to apply a unique calibration equation. All the equations follow the format Y=A*exp(B*X), and I have a spreadsheet with all the corresponding A & B parameters for each.
Is there a feasible way for me to apply these functions iteratively using ModelBuilder to speed up the process? I am also willing to learn some ArcPy to make it work. Essentially, how would I specify the A * B variables in the calculator, and then tell it to search the spreadsheet to make the right substitutions? I couldn't turn up any forum or support site posts about this.
My current plan is:
- Rename all the rasters to something logical like: "sensor_date.tif"
- Split into temporary single-bands using "Make Raster Tool"
- Feed output into raster calculator and output calibrated singlebands as .tif
- Feed new singlebands into raster calculators to find several different indices (NDVI, NDRE, SAVI, etc.)
