Automated Phenotpying

The Lemnatec Scanalyzer Field Gantry System is the largest field crop analytics robot in the world. This high-throughput phenotyping field-scanning robot has a 30-ton steel gantry that autonomously moves along two 200-meter steel rails while continuously imaging the crops growing below it with a diverse array of cameras and sensors.

Twelve sensors are attached to the gantry system. Detailed information for each sensor including name, variable measured, and field of view are available here. The planned sensor missions and their objectives for 2016 are available here.
