Product Specification

Product Name:Permanent Crop Tree Canopy Height
Product SKU:71406-00
Revision Date:2024-09-04

Product Overview

Description

Permanent Crop Tree Canopy Height characterizes tree height using 3D reconstruction derived from RGB imagery. Tree height represents the distance between the soil and tree canopy surfaces. This product utilizes a precision-aligned orthomosaic derived from high-resolution RGB imagery.

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.
