Planet-Scope
DN to Reflectance
Reflective band DN’s are converted to TOA reflectance using the rescaling coefficients in the acquisition metadata file:
\[
R(b)= reflectanceCoefficient_b \times DN
\]
where:
\(R(b)\) is the Top of Atmosphere planetary reflectance
and
\(reflectanceCoefficient_b\) the reflectance coefficient found in the product metadata, one value per band
Input
The input is an ingested Planet-Scope, see details here.
Output
The output is a STAC item geojson ... including the assets ...
