| Description:
| Aims:
To give students the knowledge and skills required to carry out an engineering survey of a small site and to instil an understanding of how terrestrial and aerial photogrammetry can be used in support of engineering projects.
Learning Outcomes:
On successful completion of the unit, the student will be able to: Demonstrate the knowledge, understanding and skills required to carry out an engineering survey of a small site, and understand the capabilities of a range of modern surveying techniques, especially in the context of engineering projects.
Skills:
Ability to use a range of surveying instruments to acceptable accuracy, to plan, execute, and process small surveying projects. Ability to determine appropriate surveying methods for specific problems.
Content:
Object and application of surveys - basic functions of survey instruments - survey planning - assessment of accuracy. Measurements of distance - direct tape measurements. Measurement of level - types of levels - levelling procedures and methods of booking - errors - reciprocal levelling - recording and plotting levels. Measurement of angles - principles and operations of the theodolite - scope of use - instrument errors and adjustments. Usage of theodolite and computation for tacheometry, traverse surveys, triangulation. Measurement of a closed traverse around a land plot and its detailed mapping. Photogrammetry: Definition, history, uses and application of photogrammetry. Stereoscopic viewing, depth perception, the human eye, principle of parallax. Terrestrial photogrammetry. Surveying accuracy/errors. Differences between random and systematic errors, assessment of accuracy. Assessment of acceptable tolerances in construction and building. The advanced use of total stations, including reflectorless systems. GPS, Laser Scanning, and any other newly developed appropriate techniques.
