A theodolite was used by students of Geology to measure horizontal and vertical angles between two set points to understand how changes in elevation (due to the underlying geology) can be measured, mapped, and represented as data. It was also used to understand optics and the behaviour of light as a wave moving through lens and materials of different density.
Using equipment like this gave students the practical experience to analyse and assess precision and accuracy in measuring devices as errors in measuring devices effect the outcomes of experiments.
Traditionally, a theodolite is used for land surveying to assess topography. It can also be used for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching.
The Heritage Centre is fortunate to have one of these instruments in the collection.
