Precision Crop Scouting
Drone flights reveal crop performance patterns that sometimes can't be seen from the ground. Using true multispectral imaging (not just RGB), we map variability across fields with high clarity. Reduced vigor, inconsistent canopy growth, nutrient imbalance, water stress, early disease onset, and pest activity all typically appear early in the data, often before they're noticeable during ground scouting.
​
Our goal is to give you clear and actionable insights you can't get from the ground. It works the same for a 10 acre block as it does for a 10,000 acre area.

Why Multispectral Imaging Matters
Most stress isn't visible from the ground or even with standard RGB drone photos. Multispectral sensors read subtle changes in leaf reflectance that indicate stress long before your eyes can pick it up. That means you see problems earlier, react faster, and protect more yield.
What Our Indexes Show You​
​​
NDVI (Normalized Difference Vegetation Index)
-
Measures: Overall Plant Vigor & Biomass.
-
Key Sensitivity: Most sensitive to total green canopy coverage and Leaf Area Index (LAI).
-
The Technical Take: A foundational index that shows the ratio of near-infrared light (strong reflection) to red light (strong absorption by chlorophyll).
-
The Benefit: Shows big-picture plant health and biomass, great for spotting weak zones, early stress, or uneven growth across a block.
NDRE (Normalized Difference Red Edge)​
-
Measures: Nitrogen Status & Mid-to-Late Season Stress.
-
Key Sensitivity: Highly sensitive to Chlorophyll and Nitrogen in dense canopies.
-
The Technical Take: Uses the Red-Edge band, which penetrates deeper into the canopy than the Red band, avoiding saturation.
-
The Benefit: Penetrates deeper into dense canopies (orchards, dense row crops), making it ideal for monitoring mid-to-late season Nitrogen needs.
​​
GNDVI (Green Normalized Difference Vegetation Index)
-
Measures: Chlorophyll Concentration & Nitrogen Uptake.
-
Key Sensitivity: Highly sensitive to early changes in active chlorophyll content.
-
The Technical Take: Utilizes the Green band, which correlates closely with chlorophyll amount, providing a sensitive measure of photosynthetic efficiency.
-
The Benefit: Highly useful for catching nutrient issues early or precisely evaluating the crop's post-fertilizer response.
​​
CIRE & CIG (Chlorophyll Indexes)
-
Measures: Advanced Chlorophyll Analysis in permanent crops.
-
Key Sensitivity: Designed for a linear and accurate measurement of chlorophyll/nutrient content.
-
The Technical Take: Advanced red-edge and green indexes that isolate chlorophyll, providing a robust measurement in high-biomass situations.
-
The Benefit: Provides deeper and more accurate chlorophyll analysis in mature permanent crops where subtle nutrient shifts are critical.
NDWI (Normalized Difference Water Index)
-
Measures: Water Content & Irrigation Issues.
-
Key Sensitivity: Most sensitive to internal leaf and canopy moisture content.
-
The Technical Take: Uses spectral bands (like NIR and SWIR) that are strongly influenced by the water held within the plant tissue.
-
The Benefit: Helps identify over or under-watered zones and stress patterns tied to soil moisture before visible wilting occurs.
RGB Ortho (Red, Green, Blue Orthomosaic)
-
Measures: Visual Confirmation & Symptom Scouting.
-
Key Sensitivity: Not a spectral index, sensitive to visible color changes and physical symptoms.
-
The Technical Take: A high-resolution, georeferenced map composed of standard visible light, providing a realistic view.
-
The Benefit: Used for scouting, ground-truthing, and visual verification of symptoms spotted in the multispectral data.
Available Deliverables

​​
-
Full-resolution RGB orthomosaic for visual scouting and documentation​

Side-by-side comparisons of RGB vs. Multispectral Index Layers​
Popular Applications
Track Nutrient Program Response
​
Multispectral drone imaging lets you validate fertilizer response and compare programs at scale. Instead of relying on a handful of tissue samples, you get a full-field view showing how every row and every zone is responding in real time.
​​
-
Verify whether a foliar or fertigation program actually improved vigor​
-
Compare treated vs untreated rows or blocks
-
Spot areas where fertilizer didn't move through drip or didn't uptake​
-
Catch underperforming zones before yield potentially drops​
Optimize Fertilizer Inputs With Zone-Level Precision
​
Multispectral mapping shows exactly where the crop is lagging and where it's already performing well. This gives PCAs and growers the evidence needed to adjust fertility plans by zone. Instead of treating the entire field the same, you can see where extra nutrients might help and where strong zones don't need them at all.
​​
-
Identify weaker zones that may benefit from additional nutrients​
-
Spot strong, vigorous areas where extra fertilizer would be wasted
-
Avoid unnecessary blanket nutrient applications across fields or blocks​
-
Improve input efficiency, supporting healthier crops and healthier soil​
Advanced Analytics
AI-supported crop intelligence built for real farming decisions.
​
Pacific Fieldworks takes RGB and multispectral imagery and processes it through advanced analytics pipelines to extract actionable insights from every acre. While some analytics are available for any crop at any stage, others are crop and stage specific, ensuring the data you receive is relevant for your current management decisions, whether you're evaluating emergence or assessing late-season risk.
What Our Analytics Deliver​​​​
Stand Establishment & Uniformity
Provides a measure of planting success, validating population targets, and highlighting row-by-row planting quality issues (e.g., Germination Rate/Stand Count, Plant Spacing & Uniformity).
​
Vigor & Biomass Mapping
Tracks detailed plant health, growth, and total vegetative mass, forming the foundation for all variable rate and nutrient management decisions (e.g., NDVI/NDRE-based Weak vs. Strong Zones).
​
Targeted Weed Control
Identifies and maps weed density and location to enable zone-level control decisions, allowing for variable rate or spot-spraying to reduce herbicide cost (e.g., Weed Pressure & Distribution, Lingering Weed Zones).
​
Soil & Water Stress
Pinpoints zones affected by saturated soil, pooling, or slow drainage, allowing for immediate irrigation adjustments and physical remediation (e.g., Waterlogging / Drainage Issues).
​
Yield Risk Assessment & Documentation
Provides a final, quantifiable report on crop performance, comparing health to benchmarks and highlighting underperforming blocks for final management decisions or insurance claims (e.g., Underperforming Blocks, Damage Detection).
​​​
​
Why This Matters for Your Operation​
​​​
Every analytics report is designed to help you move faster, scout smarter, make better timed decisions and gain valuable data for decisions during the season or for next year. Instead of guessing where to look or relying on limited sampling methods, you get a complete field-wide picture with zone-level detail. That means fewer surprises, earlier intervention, and better use of inputs.​​​​​​​​​

​​
-
Identify weed hotspots early before they spread​
-
Separate light, moderate, and heavy weed zones for better spray planning
-
Support variable rate or spot spray equipment (spray drones or capable ground sprayers)​
