I am using DJI Phantom 4 RTK Multispectral drone for my work purpose. I am wondering do I need to do white panel reflectance calibration for P4 multispectral images like Micansense? and what is the recommended camera settings if someone wants to generate an NDVI map in sunny weather condition.Any suggestions would be greatly appreciated.

We have been using the Micasense Calibrated Reflectance Panel with good results.  We took the CRP values from our panel, and I calculated what they would be for the P4MS based on the band centres and widths.

Do you need it? That depends on if you want to do repeat surveys and look for changes in NDVI and or plant health for example.

Please sen me calculated result..Or would say how to calibrate micasense panel to P4MS?
