Control Surveying

Catalog description

This course builds on the concepts learned in SUR 121 to establish vertical and horizontal control using traversing procedures and GNSS techniques. Students will be able to: (1) collect angle and distance measurements; (2) adjust a set of measured angles and compute line directions for closed and link traverses; (3) compute and adjust the departures and latitudes of a closed and link traverse; (4) use adjusted observations to compute adjusted coordinates, directions, distances, and area; (5) understand the relationships between the physical earth, the geoid, and ellipsoid; (6) perform coordinate transformations from geocentric to geodetic coordinates, and from geodetic to mapping coordinates; (7) understand the use of map projections in the state plane coordinate system, and the use of coordinate systems in large mapping and construction projects; (8) perform reduction of observations; (9) understand basic GNSS measurement principles; and (10) establish vertical and horizontal control using a variety of GNSS techniques. As part of the outdoor labs students will be able to: (1) perform a closed and link traverse survey using a total station, (2) use total station technology to establish vertical and horizontal control; (3) use GNSS technology to establish vertical and horizontal control; (4) design and establish vertical and horizontal control to support mapping and construction applications.
