# Data Sources ## Field phenotyping research sites ### Maricopa Agricultural Center (MAC), Arizona The Maricopa field site is located at the the University of Arizona Maricopa Agricultural Center and USDA Arid Land Research Station in Maricopa, Arizona. At this site, we have deployed the following phenotyping platforms. * The [**Lemnatec Scanalyzer Field System**](http://www.lemnatec.com/products/hardware-solutions/scanalyzer-field/) 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](http://terraref.org/articles/lemnatec-scanalyzer-field-sensors/). * The **PhenoTractor** is fitted with a sensor frame that supports a real time kinematic (RTK) satellite navigation antenna, a sonar transducer, an infrared temperature (IRT) scanner, and three [GreenSeeker crop sensing systems](http://www.trimble.com/agriculture/greenseeker.aspx). * **UAV** (release V1) * **Manually Collected Field Data** - Data will are collected manually using standard field methods. These measurements are used to calibrate and validate phenotypes derived from sensor-collected data. ### Kansas State University * Tractor - coming 2017 * UAV - coming 2017 ## Controlled-environment phenotyping #### Donald Danforth Plant Science Center, Missouri The [Bellwether Foundation Phenotyping Facility](https://www.danforthcenter.org/scientists-research/core-technologies/phenotyping) is a climate controlled 70 m2 growth house with a conveyor belt system for moving plants to and from fluorescence, color, and near infrared imaging cabinets. This automated, high-throughput platform allows repeated non-destructive time-series image capture and multi-parametric analysis of 1,140 plants in a single experiment. ## Genomics Genomic data includes whole-genome resequencing data from the HudsonAlpha Institute for Biotechnology, Alabama for 384 samples for accessions from the sorghum Bioenergy Association Panel (BAP) and genotyping-by-sequencing (GBS) data from Kansas State University for 768 samples from a population of sorghum recombinant inbred lines (RIL). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
