CE59700 - Coordinate Systems and Conformal MappingFall 2017
Days/Time: TBD / TBD
Credit Hours: 3
After the course the student will be able to solve most 1D/2D/3D survey problems based on rigorous 1D-, 2D- and 3D-modeling, perform coordinate transformations, assess mapping characteristics based on principles of differential geometry, develop mapping dedicated to any engineering project, generate novel engineering solutions to newly presented survey problems, evaluate 1D-, 2D-, and 3D-models, the coordinate frames used for these and their interrelationships, model the physical reality underlying most geometry-based models, in earth-fixed as well in inertial space.
The course will cover topics necessary for the modern "3D geomatics engineer/surveyor": it will give an overview of coordinate frames used in geodesy, surveying and mapping. What are the relationships between the various (3D) coordinate frames? How are the results of 1D/2D/3D surveys being mapped to a 2D, not necessarily flat, surface. Mapping models (mapping equations) and their characteristics will be discussed, based on the fundamentals of differential geometry and curvilinear coordinates.
