- Bands used by the algorithm: B2, B3, B4
- Parameters:
- c0r: atmospheric correction offset in red band B4
- cManual: (optional) manual offsets for r,g,b bands; may include manual scale factors as well
- tx, ty: position of the mid-point of the envelope for the levels color adjustment curve
- max: maximal band value (after atmospheric compensation), to be rendered as white
- sat: saturation enhancement, applied after levels adjustment
- debug: set to false to highlight pixels where any component is outside the interval
[0..1] - atmRatios: band offset ratios to use with single-parameter atmospheric correction (defaults are derived from Rayleigh scattering)
The product produces natural color images using Sentinel-2 bands 4, 3 and 2. It performs a very basic linear atmospheric correction, and applies a curve to the color components to enhance details in the dark areas, while preserving contrast in very bright snow-covered slopes. It has been fine-tuned to use on the Sentinel-2 image of Monte Sarmiento in Tierra del Fuego taken 2016-05-05.
