Survey as a profession

Surveying or land surveying is the technique,
profession, and science of determining the terrestrial
or three-dimensional position of points and the
distances and angles between them. A land surveying
professional is called a land surveyor . These points are
usually on the surface of the Earth, and they are often
used to establish land maps and boundaries for
ownership , locations like building corners or the
surface location of subsurface features, or other
purposes required by government or civil law, such as
property sales.
Surveyors work with elements of geometry,
trigonometry , regression analysis, physics ,
engineering, metrology, programming languages and
the law. They use equipment like total stations , robotic
total stations, GPS receivers, retroreflectors , 3D
scanners , radios, handheld tablets, digital levels,
drones, GIS and surveying software.
Surveying has been an element in the development of
the human environment since the beginning of
recorded history. The planning and execution of most
forms of construction require it. It is also used in
transport , communications, mapping, and the
definition of legal boundaries for land ownership. It is
an important tool for research in many other scientific
disciplines.
Definitions
ACSM
The American Congress on Surveying and Mapping
(ACSM), defines surveying as the science and art of
making all essential measurements to determine the relative
position of points or physical and cultural details above,
on, or beneath the surface of the Earth, and to depict them
in a usable form, or to establish the position of points or
details. [citation needed ]
Also per ACSM, the type of surveying known as "land
surveying" is the detailed study or inspection, as by
gathering information through observations, measurements
in the field, questionnaires, or research of legal
instruments, and data analysis in the support of planning,
designing, and establishing of property boundaries. It
involves the re-establishment of cadastral surveys and land
boundaries based on documents of record and historical
evidence, as well as certifying surveys (as required by
statute or local ordinance) of subdivision plats or maps,
registered land surveys, judicial surveys, and space
delineation. Land surveying can include associated services
such as mapping and related data accumulation,
construction layout surveys, precision measurements of
length, angle, elevation, area, and volume, as well as
horizontal and vertical control surveys, and the analysis
and utilization of land survey data.

**who is a Surveyor

A surveyor is a professional person with
the academic qualifications and technical
expertise to conduct one, or more, of the
following activities;
to determine, measure and represent
land, three-dimensional objects, point-
fields and trajectories;
to assemble and interpret land and
geographically related information,
to use that information for the planning
and efficient administration of the land,
the sea and any structures thereon; and,
to conduct research into the above
practices and to develop them.
