The Post-Baccalaureate Certificate in Geomatics is designed for students who hold a bachelor’s degree or master’s degree in fields other than Geomatics or Geographic Information Science and desire to continue their education to prepare for the Texas Board of Professional Land Surveying examination to become a Registered Professional Land Surveyor in Texas. Candidates for the certificate are required to complete 32 credit hours of surveying related courses; 20 of these credit hours must be taken at Texas A&M University-Corpus Christi. The Coordinator of the Geographic Information Science program or a designee may waive certain courses if a student has previously completed appropriate surveying courses. Students must apply for the certificate and complete a Certificate Plan approved by the Coordinator of the Geographic Information Science program or a designee.
Required GISC courses (33 Semester Hours)
An introduction to graphic and drafting principles and practices in surveying and mapping science. This course includes the development of the basic drafting skills needed to produce surveying plats and graphical presentations. The elements of descriptive geometry are addressed. A major component of the course is an introduction to the fundamentals of computer-aided drafting and design (CADD).
Historical introduction to field measurement and mapping; distance measurement using electronic distance meters; calibration and reduction. Leveling instruments; principles, construction, testing and adjustment; ancillary equipment. Optical and electronic theodolites. Traverse computations and adjustment. Coordinate systems. Map projections.
History of geodetic measurement. Description of the geodetic model of the earth. Relationship between the ellipsoid, geoid, and earth’s surface. Measurement of long baselines. Gravity and the geoid. Relationship between terrestrial observations and grid coordinates.
Principles and reduction of observations and errors in spatial measurement. Techniques of horizontal and vertical angle measurement for precise positioning. Trigonometric heighting and vertical staff tacheometry. Setting out of structures. Design and computation of horizontal and vertical curves.
Global reference systems. Use of satellite for navigation and positioning systems. History and review of satellite positioning systems. Measurement techniques using GPS. Point, differential, and kinetic positioning techniques. Error sources in satellite positioning. Future trends in satellite positioning technology.
Land ownership recording systems used in Texas and U.S. Investigation and research for artificial and natural boundaries. Title searches at county court house, title plants, and the Texas General Land Office. Other sources for cadastral research. Riparian and littoral boundaries. Boundary marking and preparation of cadastral plans. Metes and bounds descriptions. Writing field notes. Urban and rural cadastral issues.
Theory of least squares adjustment of spatial data. Use of matrices for the solution of equations. Propagation of variances and statistical testing of adjustment solutions. Error ellipses and confidence intervals. Use of spatial data reduction software.
A one-week field camp undertaking projects in cadastral, engineering, hydrographic, and geodetic positioning. Reduction of digital field data to produce final plans and reports. Taken during the senior year.
History of land and legal systems in Texas, including influences by Spain, Mexico, the Republic of Texas, and the State of Texas. Nature of land development in Texas. History of surface and mineral land tenure in Texas. Evolution of principles of land ownership boundary determination in Texas.
Introduction to geographic information systems (GIS) and its theoretical foundations. Topics covered include vector and raster data models, acquisition and manipulation of data, cartography, current topics, data quality, and basic spatial analysis. Principles and uses of GIS software also covered.
Students must earn at least a 2.0 overall grade point average in all GISC courses.
