INTRODUCTION TO BASIC GEOMATICS

Surveying is a part of study in Civil Engineering which deals with the preliminary works in every construction. The change of name from the long-used Surveying to Geomatics has been in progress as a part of development in both the scope of the study and the development of instruments used.

The first part of this course is Basic Geomatics (Elementary Surveying). This course introduces students to the procedures of measurements both horizontal and vertical distances as well as angles and directions. After which, traversing and determination of area would be discussed.

Horizontal measurement is done with pacing - unconventional method, and taping - conventional method. Vertical measurements would be using leveling methods.

Fieldworks included in this course are the following:

• Introduction
• Pacing
• Taping on Smooth and Level Ground
• Taping on Sloped and Uneven Ground
• Determining Area of a Rectilinear Field by Tape
• Area of a Lot Bounded by a Curve Offset at Irregular Interval
• Two-peg Test
• Differential Leveling
• Three-wire Leveling
• Reciprocal Leveling
• Profile Leveling
• Open Compass Traverse
• Closed Compass Traverse
• Interior Angle Traverse
• Deflection Angle Traverse
• Azimuth Traverse
