Product Specification
Product Name:Precision Aligned Multispectral and/or Thermal Crop Health Mosaic
Product SKU:71303-12
Revision Date:2024-07-24
Product Overview
Description
Precision Aligned Multispectral and/or Thermal Crop Health Mosaic provides measurements of Blue (B), Green (G), Red (R), Red-Edge (RE), Near-Infrared (NIR), and Long-Wave Infrared (LWIR) spectral bands and derivate vegetation indices. This product utilizes orthomosaics derived from high-resolution 6-band multispectral imagery captured across an entire field. Specific deliverables for this product are sensor dependent. Multispectral imagery that does not include the particular 6-band configuration of B, G, R, RE, NIR, and LWIR will include only a subset of deliverables.Recommended Use Cases
- Plant Growth
- Canopy Development
- Canopy Senescence
- Crop Health
- Crop Stress
- Nutrient Status
- Disease
- Water Stress
- Heat Stress
- Crop Damage
- Area of Interest Variability
- Image Scouting
- Image Anomaly Detection
Supported Crops

Environmental Conditions
Lighting
Imagery should be captured between the time of 3 hours after sunrise and 3 hours before sunset. Consistent lighting conditions required for best results, including avoidance of hard shadows cast over the field which cause bright spots and dark spots in the dataset.Wind
Wind conditions should be within the specified limits of the aircraft or system being used to carry the imaging sensor.Precipitation
There should be no active precipitation during imagery capture.Deliverables

Visualized Layers
Composite, Single-band, and Index visualized layers are dynamically rendered in FieldAgent. Composite layers include Color Infrared (NIR, R, G) and Natural Color (R, G, B). Single band layers include Blue (B), Green (G), Red (R), Red Edge (RE), Near Infrared (NIR), Long Wave Infrared (LWIR). Index layers include Normalized Difference Vegetation Index (NDVI), Normalized Difference Red Edge Index (NDRE), Green Normalized Difference Vegetation Index (GNDVI), Green Leaf Index (GLI), Chlorophyll Index Red Edge (CIRE), Chlorophyll Index Green (CIG), and Normalized Difference Water Index (NDWI). Multispectral imagery that does not include the specific band(s) needed to render a given layer will not be visualized.
