1.0 INTRODUCTION
This document is meant to serve as a guide and reference for the use of the Leica
TC407 Total Station in the CEE 121 Civil andEnvironmental Engineering Measurements
class at the University of Massachusetts Amherst. The general use and operation of the
TC407 is discussed as well as the specific operations: 1) a topographic survey, 2) a
survey to calculate area, and 3) an “as-built” survey.
2.0 EQUIPMENT AND ORGANIZATION
It is important to have a plan for every survey. The goals, methods, and general
approach should bediscussed before the survey begins. A list of equipment should be
compiled, the batteries should be charged, and each member of the survey crew should
have an understanding of what is happening and what their specific responsibilities will
be during the survey. The method of note taking should also be discussed beforehand,
and the note taker and surveyor (if different) should maintain frequentcommunication
and discussion throughout the survey. It may be preferable, for educational reasons, to
alternate responsibilities over the course of the survey so that each member of the crew
learns the various crew duties.
3.0 GETTING STARTED
Once you are at the location of the survey with all your equipment, it is a good
idea to “walk over” the survey site and consider suitable instrument...
