I am appying the C2RCC algorithm to retrieve the Kd value (resulting band Kd489 ). However, I need to automatize it and I have used GPT, but it takes a lot of time (around 1 hour only a “small” piece of the image). To decrease that time I wanted to save the pre-processed images (resampled, reprojected, clipped and with only the needed bands before. Can I store the pre-processed image in GeoTIFF or another format and then apply the C2RCC algorithm? Can I remove some bands before applying the algorithm or I need all bands to apply it?
You can resample the data before, but you don’t have to reproject it.
GeoTiff should work, but probably it is better to use NetCDF4-BEAM or BEAM-DIMAP.
As input, are the radiance bands and the angle (sun and view) bands necessary.
If not already done, you can disable the computation of the uncertainties. This takes a lot of time.
