Product Name:Plot Canopy Cover with Uniformity and Change
Product SKU:71204-01
Revision Date:2024-07-24
Product Overview
Description
Plot Canopy Cover with Uniformity and Change characterizes the extent of and change over time of vegetation cover, and is related to measurements of ground cover, biomass, and leaf area index. This product utilizes a precision-aligned orthomosaic derived from high-resolution RGB imagery and measurement of canopy cover from a previous image capture date.Recommended Use Cases

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
