Do I need a multispectral camera?

No. Any standard RGB drone camera works — DJI, Autel, or anything that produces a JPEG or PNG. That's the point: skip the multispectral hardware cost entirely.

Which crops are supported in India?

Wheat, paddy/rice, sugarcane, cotton, and grapes — the crops most Indian drone operators actually fly over. If your crop behaves unexpectedly, send us a frame and we'll tell you honestly.

How fast is inference?

A single frame returns in seconds over one HTTPS endpoint. Batch uploads are processed in parallel.

How do I integrate it?

One REST endpoint. POST an image, receive the stress map plus zone summaries as JSON, GeoTIFF, or PNG. Most teams ship an integration in an afternoon.

Pricing is coming soon. The live demo is free, no card required — and early pilot partners get priority access and pricing input.

— NDVI vs RGB

NDVI vs RGB drone imagery: same decision, without the payload.

Traditional NDVI crop health mapping needs a multispectral camera that costs several times an RGB rig. The overwhelming majority of drones already flying Indian fields carry RGB cameras. Nabhya extracts a near-NDVI vegetation stress signal from the hardware you already own.

API documentation How the pipeline works

— FAQ

Asked first, answered straight.

No — and we say so. NDVI needs a near-infrared band. Nabhya predicts an NDVI-correlated vegetation stress index from RGB alone, validated against same-day multispectral NDVI captures. For scouting and zoning decisions, the map agrees with NDVI where it matters.

— Why Nabhya

Inspect first, then spray.

Nabhya was built in Greater Noida by an agriculture student from Munger, Bihar, who grew up watching family land split smaller with every generation. Smaller plots leave less room for error — and less money for hardware.

A multispectral payload costs several times an RGB rig, while the overwhelming majority of drones already flying Indian fields carry RGB cameras. So rather than asking operators to buy new hardware, Nabhya extracts a near-NDVI vegetation stress signal from the hardware they already own — delivered as a cloud API, so it fits into a workflow instead of replacing one.

From the field notes.
