The concepts of gravity, and its use in surveying. Computations with coordinates, and transformations of coordinates. Map projection systems. Hydrography and Marine Positioning Objective - The student is presented with an introduction to hydrographic surveying and marine positioning and a review of horizontal and vertical datums along with the issues facing the marine surveyor when working in different datums. Operational scenarios include rig location, pipelay and inspection surveys, jacket placement and maintenance, vessel management systems, cable laying, seismic data acquisition.
Students work with larger data sets, involving three dimensional coordinates.
Emphasis will also be given to oral communications. Typical topics include holding meetings, proposal writing, progress reporting, writing technical instructions, advanced presentation skills with an emphasis on oral communications. A major research report forms an integral part of the course. To continue the students training in astronomical techniques, using more precise instruments. To introduce the concepts of astronomical coordinate variation, time systems and star catalogues.
