Bought rebuild Inspire 1 quad copter and bought modded camera for NDVI. The information that came with it says :


new OCN (Orange+Cyan+NIR) filter.

The first thing to notice is that all 3 of the bands are different,
even the near-infrared (NIR). Instead of red light it captures orange,
instead of green it captures cyan (blue-green) and instead of 850nm
NIR, it captures 808nm NIR. The bandwidths are also slightly wider to
provide more contrast.


QUESTION: In FIJI, which bands do I use for NDVI calculation? Is the 808NIR band the BLUE band in RGB?

Thanks,
