Drone flying over crop
Nation prepares to develop standards and protocols for widespread use

A 2012 Congressional mandate directed the Federal Aeronautics Administration (FAA) to begin integrating civilian unmanned aircraft (aka drones) into the national airspace (NAS) by the end of 2015.

FAA regulates all flight through U.S. airspace. Until now, the agency has allowed only public entities with special FAA permits, called Certificates of Authorization (COAs) to fly unmanned aircraft, mostly for research purposes.

On December 30, FAA picked six test sites from …

What is geospatial science?

Geospatial is a combination of geography and spatial.  Geography is a science about the earth.  Spatial is about the space around us.  Geospatial describes the use of spatial analysis with geographic information.…

Overview of Precision Agriculture

An Overview of Precision Agriculture

Prepared By: Dr. John Fulton and Daniel Mullenix, Auburn University


Highlights of Precision Agriculture[[1]]

Precision agriculture, also called “farming by the foot”, can be defined as a comprehensive system designed to optimize agricultural production through the application of crop information, advanced technology and management practices. A truly comprehensive approach to precision agriculture begins with crop planning and includes tillage, planting, chemical applications, harvesting, and post harvest processing of the crop. Basically precision agriculture is …

When farmers or ranchers observe their fields or pastures to assess their condition without physically touching them, it is a form of remote sensing. Observing the colors of leaves or the overall appearances of plants can determine the plant’s condition. Remotely sensed images taken from satellites and aircraft provide a means …

Kraig Nelson, Graduate Student

The Global Positioning System (GPS) provides opportunities for agricultural producers to manage their land and crop production more precisely. Common names for general GPS applications in farming and ranching include precision agriculture, site-specific farming, and prescription farming. GPS applications in farming include guidance of equipment such as sprayers, fertilizer applicators, and tillage implements to …
