Empirical line

source module isofit.utils.empirical_line

Functions

  • empirical_line — Perform an empirical line interpolation for reflectance and uncertainty extrapolation Args: reference_radiance_file: source file for radiance (interpolation built from this) reference_reflectance_file: source file for reflectance (interpolation built from this) reference_uncertainty_file: source file for uncertainty (interpolation built from this) reference_locations_file: source file for file locations (lon, lat, elev), (interpolation built from this) segmentation_file: input file noting the per-pixel segmentation used input_radiance_file: input radiance file (interpolate over this) input_locations_file: input location file (interpolate over this) output_reflectance_file: location to write output reflectance to output_uncertainty_file: location to write output uncertainty to
