INTRODUCTION

Question 1

The science concerned with the measurement, representation, analysis, management, retrieval and display of spatial information describing both the earth’s physical features and the built-in environment.

Answer 1

Geomatics/Surveying

Question 2

The art of making measurements of the
relative positions of natural and man-made features of the earth’s surface, and the presentation of this information either graphically or numerically.

Answer 2

Surveying

Question 3

The art and science of determining angular and linear measurements to establish the form, extent, and relative positions of points, lines, and areas on or near the surface of the earth or on other extraterrestrial bodies and the use of specialized equipment and techniques.

Answer 3

Surveying

Question 4

Uses of Surveys

Answer 4

❑Establishment of boundaries of land
❑Fixing of national and state boundaries
❑Charting of coastlines and navigable streams and lakes
❑Precise location of definite reference points throughout
the country
❑Collection of valuable facts concerning the earth’s
magnetism at widely scattered stations throughout the
country

Question 5

the mean surface of the earth is considered as a plane, or in which its spherical shape is neglected

Answer 5

Plane Surveying

Question 6

takes into account the true shape of the earth

Answer 6

Geodetic Surveying

Question 7

Types of Surveys

Answer 7

Control Survey
Property Survey
Topographic Survey
Hydrographic Survey
Mine Survey
Route Survey
Construction Survey
Photogrammetric Survey

Question 8

consist of the establishment of network of horizontal and vertical monuments that serve as reference framework for initiating other surveys.

Answer 8

Control Survey

Question 9

are usually closed surveys which are undertaken in urban and rural areas for the purpose of determining and defining property lines, boundaries, corners, and areas. These surveys are also made to fix the boundaries of municipalities, towns, and provincial jurisdictions.

Answer 9

Property/Cadastral Surveys

Question 10

are made to determine the shape and configuration of ground terrain as well as locations and elevations of natural and human-made objects which are essential in the generation of topographic map.

Answer 10

Topographic Surveys

Question 11

are made to map shorelines, chart the shape of underlying water surfaces of lakes/oceans, and measure the flow of streams.

Answer 11

Hydrographic Surveys

Question 12

are essential for the purpose of navigation, water supply, or subaqueous construction.

Answer 12

Hydrographic maps

Question 13

are performed above and below the ground to guide tunneling and other operations associated with mining such as geophysical surveys for mineral and energy resource exploration.

Answer 13

Mining Surveys

Question 14

involve the determination of alignment, grade, and earthwork quantities in connection with the planning, designing, and construction of highways, railroads, pipelines, canals, transmission and other linear projects.

Answer 14

Route Surveys

Question 15

are undertaken in construction site to provide data regarding alignment, grade, elevations, locations, and dimensions of structures

Answer 15

Construction Survey

Question 15

uses camera that is carried usually in airplanes to obtain images.

Answer 15

Photogrammetric Survey

Question 16

utilizes the principle of aerial and terrestrial photogrammetry, in which measurements made on photographs are used to determine the positions of photograph objects.
