Product Specification

Product Name:Field Scale Stand Count
Product SKU:71301-00
Revision Date:2024-05-22

Product Overview

Description

Field Scale Stand Count provides plant population count and emergence percentage across a field. 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.

Recommended Use Cases

  • Plant Population
  • Seedling Emergence
  • Plant Growth
  • Yield Potential
  • Area of Interest Variability

Supported Crops

  • Corn/Maize
  • Soybean
  • Cotton

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.

"Stand Count and 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. "Stand Count and 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.
