Product SKU:71304-01

Revision Date:2024-01-08

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.

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.
