distances, determining relative positions of points on or beneath the
surface of the earth, or establishing such points.

5
It includes establishment or re-establishment of real property boundaries.

It is an essential part of construction that is performed to establish reference points and markers that will guide the construction.

12
The practice of measuring and mapping on-ground or underground points for the purpose of exploiting and utilizing mineral deposits.

Provides the data needed to determine horizontal and vertical alignment, and even earthwork quantities, for the design of linear structures such as roads, railways, pipelines, etc.

43
Defined as the horizontal angle the line makes with an established line of reference.
Direction of a Line
44
Kinds of angles which can be used to describe the direction of lines:
Interior Angles, Deflection Angles, Angles to the Right, Bearings, Azimuth
45
Are angles between adjacent lines in a closed polygon.

48
Are measured clockwise from the preceding line to the succeeding line.
Angles to the Right
49
The direction of a line may be described by giving its __.
Bearing
50
The acute horizontal angle between the reference meridian and the line.
Bearing of a Line
51
Measured clockwise from the north.
Whole-Circle Bearing
52
The actual angle between the reference meridian (either north or south) and the line.
Reduced Bearing
53
Are horizontal angles observed clockwise from any reference meridian.
Azimuths
54
In plane surveying, they are generally observed from the north, but astronomers and the military have used the south as the reference direction.
Azimuths
55
They used the south as its reference for azimuths for __, but the north has been adopted for __.
National Geodetic Survey (NGS), NAD27, NAD83
56
For long sights and accurate levelling work, the __ of the earth and __ of the line of sight shall have to be taken into consideration.
