Advanced survey traverse and triangulation calculations and adjustments including error analysis, error distribution, subdivision of sections, contouring, route locations, grade determinations, earthwork measurements, map plotting, and coordinate geometry such as inversing between points and line intersections. The course will include fieldwork such as; traversing, direct and reverse angles, property corner searches, EDM calibration, construction location and grade staking, building layouts with offset stakes. These labs will be done using Total Stations, Data Collectors, and GPS. Prerequisites: CT 121 and MATH 136. (S)
