GPS/GIS Facilities

The school of Agriculture and Natural Resources currently has facilities for both global positioning systems (GPS) and geographic information systems (GIS).  Morrisville State College operates a GPS/GIS computer laboratory to train students in this cutting-edge technology. The students use the laboratory to gain hands-on experiences on both GPS and GIS.  The laboratory (located in 204 Charlton Hall) is equipped with 16 state-of-the-art computer systems that run both ArcView GIS 3.3 and ArcGIS 8.3 (both a product of the Environmental Systems Research Institute, ESRI).

GPS utilizes specially-coded satellite signals that can be processed in a GPS receiver, thereby enabling the receiver to accurately mark our position on or above the earth's surface.  Students who take precision farming, soil and crop science, photogrammetric mapping, and GPS/GIS classes use 204 Charlton for a variety of exercises and projects including field mapping and GIS.  The students also collect GPS data using a variety of GPS systems (more than 18 Garmin GPS 12 and Magellan GPS 310 units) including real-time and post-processing differential GPS (DGPS).  The real-time DGPS systems include a couple of Trimble GeoExplorer 3.0 units with a beacon-on-a-belt for receiving differential corrections from the USCG  beacons.  Numerous WAAS-based DGPS systems are also available for classroom instruction, laboratory exercises, and class projects.  These include Garmin GPS 72, Garmin GPS 76, and Standard Horizon NAV 40 real-time DGPS systems.  A  post-processing DGPS system is also available.  The Ashtech system is comprised of a roving unit and a base station located in Charlton Hall (computer software is utilized in this case to differentially-correct the collected GPS data).  Finally, a John Deere GreenStar precision farming is also available for both teaching and demonstration.  The system includes a StarFire GPS receiver that allows for real-time differential corrections of GPS measurements based on signals from a satellite or the WAAS operated by the Federal Aviation Administration (FAA).
