reflectance should look like [(1-n)^2+k^2]/[(1+n)^2+k^2] nd you can remove k for very transparent materials.
absoprtion should look like 4*pi*k/lambda where lambda is wavelength of light
Also ad…

STAC Browser works great with visual imagery, and I think in theory it'll support full bit depth multispectral data, but on the planet open data it seems to struggle.

There was a suggestion at the June 24, 2024 Ocean Reflectance PFS call that all of the CEOS-ARD PFS sections describe metadata requirements, and so the sections should be renamed as follows:

Hey there,
I am a bit confused, hopefully someone can help me. I am trying to write my own SPPM implementation and currently I am working on Motion Blur. To have some kind of reference, I took a loo…

Reflectance data are calibrated between 0 and 1 (mostly). When we control the color limits using the little arrows, the limits always increase or decrease by 1. This is a useful increment for bright…

Hi, thanks for your excellent work. I have a question: what's the unit of Rayleigh reflectance?
Here is the sample code to get Rayleigh reflectance:

I accidentally passed a "reference_reflectance_file" in the input block which had not been resampled to instrument wavelengths. This caused a division operation with vectors of mismatched dimension. …
