Product Specification
Product Name:Field Scale Gridded Flower Cover
Product SKU:71305-01
Revision Date:2024-07-24
Product Overview
Description
Field Scale Gridded Flowering characterizes the extent of specifically colored pixels (e.g., yellow, white, etc.) and is related to measurements of timing and/or extent of flowering or similarly expressed phenological development. This product utilizes a precision-aligned orthomosaic derived from high-resolution RGB imagery.Recommended Use Cases

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
