Four years ago I produced a short video with Jack Berry, who helps run a topographical mapping company. Jack was hired to make a map of a ten acre tract of land in west Cobb County, and I followed him as he obtained four GPS points around the county. As he explains in the video, his map compilers combine the GPS points he gathers with an aerial photograph to produce the detailed topographic map. This segment reveals the rapid pace of development in Cobb County in the past two decades.
