Product Specification
Product Name:Field Scale Gridded Canopy Cover
Product SKU:71304-01
Revision Date:2023-11-18
Product Overview
Description
Field Scale Gridded Canopy Cover characterizes the extent of vegetation (i.e., green), and is related to measurements of ground cover, biomass, and leaf area index across a field. This product utilizes a precision-aligned orthomosaic derived from high-resolution RGB imagery.Recommended Use Cases
- Seed Vigor
- Plant Uniformity
- Stand Quality
- Plant Growth
- Biomass
- Canopy Development
- Leaf Area Index
- Radiation Interception
- Canopy Senescence
- Crop Health
- Crop Stress
- Nutrient Status
- Disease
- Area of Interest Variability
- Conservation Practice Detection
- Carbon Credit Monitoring, Reporting, and Verification
Supported Crops
- Any Crop

Environmental Conditions
Lighting
Imagery should be captured between the time of 2 hours after sunrise and 2 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
