Product Specification

Product Name:Field Scale Male/Female Stand Count with Uniformity
Product SKU:71301-02
Revision Date:2024-05-22

Product Overview

Description

Field Scale Male/Female Stand Count with Uniformity measures early season crop performance including measurements of stand count and related uniformity measurements across a field. This product independently quantifies metrics across male and female row planting pattern. This product utilizes high-resolution RGB imagery captured at sampled locations across a field to deliver a Spot Scout layer. Specific deliverables for this product are crop dependent.

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.

"Male Female Stand Count with Uniformity - Individual" is delivered when data capture for Corn occurs at V2-V3 growth stage (based on leaf collar method) and with non-overlapping plants. "Male Female Stand Count with Uniformity - Rowfill" is delivered when data capture for Corn occurs at V4-V5 growth stage (based on leaf collar method) or when plants are overlapping. The deliverable can vary between Male and Female rows based on growth stage and plant size.

Spot Scout Male/Female Stand Count with Uniformity (84001-03)

Description

Provides either an absolute plant count or a relative plant count using percent row-fill based on planting population as well as related uniformity statistics including plant population, gap analysis, seed spacing, singulation/skips/multiples, canopy cover, and weed cover. When applicable, metrics are individually provided for male and female rows.
