Product Name:Field Scale Gridded Crop Health
Product SKU:71303-10
Revision Date:2024-07-24
Product Overview
Description
Field Scale Gridded Crop Health provides measurements of vegetation indices including Normalized Difference Vegetation Index (NDVI), Normalized Difference Red Edge Index (NDRE), or Visible Atmospherically Resistant Index (VARI). This product utilizes precision aligned orthomosaics derived from high-resolution NDVI, NDRE, or RGB imagery. Specific deliverables for this product are sensor dependent.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
