Mavic 3M Output ranges in Pix4D Fields

Hi,

From what I can tell, the M3M is collecting MSI data in a 16 unsigned integer format. The output from Pix4D fields is in a float32 format with typically the min and max values for different bands somewhere between 0 and 0.05. Is this correct? I was expecting the min and max to be 0 and 1. This is the how we are getting the outputs when stitching data collected with Micasense Altum.

Thanks.

Hi,

The M3M is not radiometrically calibrated, you will need to use a reflectance target to get absolute reflectance values.

Otherwise, you get arbitrary values that are only meaningful relative to each other.
