Evans County 4-H students recently visited the Geographic Information Systems (GIS) Technology program at Ogeechee Technical College. Twenty students, who were in grades four through 12, started the day on the OTC campus with a welcome by Dean John Groover, before beginning educational activities. During the early part of the day, the students participated in a treasure hunt using Global Positioning Systems (GPS) receivers, internet mapping activities using Google Earth, and 3-D modeling using Inventor software, under the guidance of Computer Aided Drafting instructor, Ty Riggs.
