Surveying Computations
Unit code: UDB283
Contact hours: 4 per week
Credit points: 12
Information about fees and unit costs
This unit includes the use of advanced scientific calculators and their application for geometric computations, solution of road and area problems, missing data closes, and simple curve problems. It offers solutions for more difficult problems including the three point problem, interrupted bases and various types of curve problems. It introduces spherical trigonometry, the solution of spherical triangles and the use of spherical trigonometry to determine position and direction on the Earth's surface from observation to astronomical objects. Practical exercises determine position and direction.

Sample subject outline - Semester 1 2013
Note: Subject outlines often change before the semester begins. Below is a sample outline.
Rationale
Spatial positioning of objects, features and boundaries is a standard surveying and mapping activity and involves computation. Accordingly, it is essential that students become efficient in surveying computations in order to be able to operate effectively in the workplace. This unit provides grounding in plane surveying computations so that you can carry out basic surveying activities. It also provides the foundation for subsequent, more advanced surveying units that the students undertake in later years of the course.
Aims
The aim of this unit is to provide an introduction to computations on plane and curved surfaces.
Objectives
By completion of this unit you should be able to demonstrate the following discipline specific capabilities at intermediate level:
1. Use a programmable scientific calculator for computations.
2. Carry out traverse, intersection, resection, plane transformation and horizontal curve computations.
3. Understand the elements of spherical trigonometry, take astronomical observations and compute directions on the surface of the Earth.
4. Demonstrate an understanding of the principles and characteristics of the common map projections used in surveying.
Content
- Calculator programming principles: variables; expressions; loops; conditional statements; arrays; error traps
- Direct solutions: determination of traverse misclosure; angular adjustment; coordinate adjustment; application of weights
- Indirect solutions: intersections by angles, bearings and distances; 3-point resection by directions; plane conformal transformation of coordinates
- Horizontal curve calculations: circular and transition curves; missing parameters; setout of intermediate points on the curve
- Introduction to spherical trigonometry: definition of sphere; circles on sphere; spherical excess; geographic coordinates; celestial sphere; equatorial coordinates; horizon coordinates
- Azimuth determination by astronomical observations: solar and stellar observations; hour-angle method; altitude method
- Introduction to map projections: plane, cylindrical and conical projections; Mercator and Transverse Mercator projections.
