NDVI drone vs NDVI camera: do you need multispectral?

When a multispectral camera is the right call

• Research protocols that need calibrated, absolute index values
• Comparisons across seasons, farms or sensors
• Red-edge indices for specific agronomic models

When RGB is enough

Most in-season decisions are ranking decisions: which zone to scout, sample or treat first. Relative vigour within a field answers these, and an RGB camera plus a model trained on paired NDVI samples can provide it.

The cost of each path

• Multispectral: extra hardware, panel calibration each flight, heavier processing
• RGB with Nabhya: the drone you already fly, one API call per frame
