Upon successful completion of this course, the student will be able to:
Discuss the principles, concepts, observing techniques and instrumentation of high-precision surveys, including sources and types of errors as they relate to the techniques and instruments.
Interpret precision, accuracy standards and survey specifications for conducting terrestrial and GPS surveys.
Carry out error analysis of survey measurements, such as angles (directions), distances, and height differences.
Design by pre-analysis the appropriate combination of survey techniques (conventional and GPS) and equipment for field data collection to satisfy specified quality requirements (in 1D, 2D and 3D).
Carry out simple Calibration and testing of survey equipment using standardized methods and procedures.
Assess data gathered for the calibration and testing of survey equipment, for precision measurements.
Carry out a variety of precise measurements and calculations to test and assess accuracy and limitations of survey equipment.
Carry out a variety of precise measurements and calculations to obtain three dimensional coordinates of targeted points located on an object or surface.
Analyse the positioning accuracy and applications of three-dimensional coordinating systems, including terrestrial laser scanner systems and photogrammetric methods.
Explain some aspects of deformation monitoring techniques and analyses.
Describe the techniques of alignment and underground (tunnelling and mine) surveys.
Carry out azimuth-determination project and perform necessary reductions in order to obtain astronomic azimuths and the grid azimuths.
