BackgroundSurveying:

a technique and science which encompasses all methods formeasuring and collecting information about the physical earthand our environment, processing that information, anddisseminating a variety of resulting products to a wide range ofclients.

Physical earth Processing tool Clients

The field work in surveying:allows students to handle a range of tools and instrumentsincluding chains, levels, transits, theodolites, electronic distancemeasurements, and total stations, and to learn the measurementtechniques useful in the Civil Engineering practice.

Background …

On successful completion of this field work, students should beable to:♦ Illustrate an understanding of accuracy of measurement

required in surveying;♦ Illustrate a skill of the principles and techniques of basic

surveying;♦ Identify suitable equipment required for tasks in basic

surveying;♦ Show how to reduce data obtained from fieldwork to a

useable form;♦ Develop a skill to interpret and analyze the data using

different software;♦ Mastery of skills for using Geographical information

Systems (GIS) software.

Objectives

Field work AssessmentThe evaluation will consist:

♦ field work reports;

♦ term project;

♦ exams.

This part of the course accounts 30% of the total mark for thecourse.

♦ Students will work in groups

♦ Each and every student is responsible forsubmitting a separate field notes

♦ Term project will be submitted in groups.

Notice

Field Notes

♦ Measurements

♦ Sketches

♦ Descriptions

♦ Miscellaneous information

Filed notes are the records of work done in the field.

In practice, these records are kept for later computations inthe office or may be used as evidence in a court of law.

Typically, they contain:
