Traversing Computations: (Chapter 10) Closed traverses like closed level loops offer a opportunity
to check ones work and make adjustments because extra measurements have been make to form a
loop. Adjustment steps include:
1. Balance Interior Angles [Lect
Angle Measurement: (Chapter 8) We have provided good coverage of distance measurement with
total stations. However, our treatment of angle coverage will be light as this is covered adequately in
the field course. You should now be familiar with setting up
Differential Level Errors
We discussed the Canadian datum used in leveling and leveling methods and equipment in the field
practice. However, there are a number of errors that we should consider in more detail when
determining vertical distances from one

Global Positioning Systems (GPS): (Chapter 13 &14). The advancement of computing and space
technology is changing the role of the traditional surveyor. Today, the discipline is known as Geomatics
rather than Surveying in part to recognize these technology
Taping Errors: (Section 6.14-6.16) Taping equipment and methods have been covered in
the field school. However, it is useful to consider taping errors which consist of:
1) Incorrect Tape Length Correction
2) Temperature Correction
3) Pull Correction
4) Sa
Errors in Observation (Section 3.1 & 3.3)
Observations (other than counting) will always contain error. The errors nor the true value can
never be known. However, we can estimate the error. Error can be managed by designing the
system of measurement using

Definition of Surveying
Surveying is the technique and science of accurately determining the relative position of points
on, above, or beneath the surface of the earth or of establishing such points.
Read Chapter 1 to understand the extent and responsibil
Distance Measurement Errors (Chapter 6)
We have reviewed at vertical distance measurement and identified errors associated with those. Now
we turn to horizontal distance measurement. There are a number of methods to determine horizontal
distance. In our f
Coordinate Geometry: (Coordinate Transformations). Sometimes it is difficult to work directly in a
geodetic based reference coordinate system. In these cases we might start our work in a local frame of
reference and then later translate it to a geodetic f
Electronic Distance Measurement (EDM) Error: (Section 6.17- 6.24) Distance measured
using a total station is based on the measurement of the phase angle of the return beam of
electro-magnetic (EM) energy as it is transmitted over a two-way distance betwee
Angle, Azimuths and Bearings: (Chapter 7) In this chapter we will be most concerned with the
calculation of line azimuth rather then bearings. However, knowledge of bearings is useful
especially for interpreting older surveys determined from magnetic refe
