Levelling Tutorials - Introduction
Aims and Audience
This on-line tutorial is intended to support practical taught sessions for students who are beginning surveying at trainee level. As such it is an on-line reference and revision resource rather than a stand alone teaching pack.
The resource covers the basic skills of setting up a tripod and levelling the instrument, and is suitable for students who are coming to terms with using surveying instruments for the first time. It has been developed for students of surveying at Orkney College. Surveying is taught to FE and post graduate students.
The intention is that this resource will reduce time spent by the tutor at the beginning of practical sessions repeating the basic setting up procedures for instruments so that students can spend more of their time gathering survey data.
Learning Outcomes
At the end of this tutorial, and the associated practical sessions, you will be able to set up and use an automatic level. These skills are transferable to setting up other instruments using the three foot screw system such as theodolites.
Time requirement
Allow 2 hours
to work through the full sequence of exercises for the first time.
As a revision resource select the sections that you want to go over again
from the home page and work at your own pace.
Assessment
There are online activities to encourage you to test understanding. However, setting up and using a surveying instrument is a practical skill and can only be fully assessed by practical demonstration with 'live' instruments under site conditions.
Date of creation
Photographs and diagrams were created specifically for this project during November and December 2002.
