Sara Loechel, a remote sensing researcher at the University of Maryland, labels fields, woodlands, and streams on a computer, while ARS agronomist Craig Daughtry locates the same features on an aerial photograph of the Beltsville [Maryland] Agricultural Research Center. The computer image will form the base layer of a geographic information system map. Other data about soils, crops, and management practices will be added, along with remotely sensed images of crops to update their growth and development.
