Before a crop shows visible signs of nitrogen deficiency, drought stress, or early disease pressure, its canopy has already changed — just not in a wavelength the human eye can register. HP-Cedar I's 6-band multispectral sensor suite is built to catch that change first.
Why Visible Light Isn't Enough
Chlorophyll reflects strongly in the near-infrared and absorbs heavily in red and blue bands. When a plant is stressed, its internal cell structure and chlorophyll content shift measurably in these bands weeks before any visible yellowing or wilting appears on the leaf surface.
"By the time you can see stress with your own eyes, you've already lost two to three weeks of intervention window. Multispectral imaging gives that window back." — Dr. Elena Marsh
How the Flight Works
A typical HP-Cedar I survey mission covers 150–400 acres per flight, capturing red, green, blue, red-edge, near-infrared, and thermal bands simultaneously at 3cm/pixel resolution. Onboard processing normalizes each band against a calibrated reflectance panel captured pre-flight.
- NDVI (Normalized Difference Vegetation Index) for general vigor mapping
- NDRE (Red-Edge) for early-stage nitrogen and chlorophyll stress
- Thermal delta mapping for water-stress hotspots
From Data to Decision
Raw imagery is stitched into a georeferenced orthomosaic within hours of landing, then exported directly into common farm management platforms. Zone maps flag stressed regions with prescription-ready shapefiles, so a variable-rate applicator can act on the same day the data was captured.
Field Results
Across our 2024 field trial season, operators using multispectral scouting reported catching nutrient and water stress an average of 16 days earlier than visual scouting alone, with fungicide and fertilizer input reductions of 18–42% depending on crop and season.
