Hi,

I need gain and offset value for every band? I want to calculate reflectance.

(Radiance=DN*gain +offset) 

How can i reach this values? Thanks.

  Hi Seyma,

  While we don't publish gain & offset values for Planet imagery, you can use the reflectance coefficient provided in the imagery metadata to convert analytic TOA radiance values to TOA reflectance. You can read more about this in the full imagery product spec (PDF download link).
