Product Name:Field Scale Stand Count (Offline)
Product SKU:71301-03
Revision Date:2024-03-18
Product Overview
Description
Field Scale Stand Count (Offline) 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. Offline stand counts can be run on FieldAgent Desktop and FieldAgent Mobile.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.Deliverables
