Product Specification

Product Name:Plot Senescence Status
Product SKU:71211-01
Revision Date:2024-07-24

Product Overview

Description

Plot Senescence Status characterizes the extent of vegetation cover as well as relative maturity and growth stage, 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.

Very small plot trials may require increased overlap, increased buffer, and/or decreased altitude to ensure a minimum of 6 flight passes over the trial.

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.

Plot Canopy Cover with Uniformity and Senescence Status (83002-02)

Description

Summarizes the green pixels (i.e., vegetative cover) within a plot. Uniformity describes variation at the plot-level using statistical summary of sub-plot-level data. Senescence Status provides a relative assessment of maturity status.
