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 ...
