The practice of creating points using specified angular and linear measurements is
commonly referred to as surveying. The size and volume of a particular piece of land can
be determined using the plans, sections, and maps created through surveying. The
horizontal projection of the surveyed area, rather than the actual extent, is depicted on a
map. Drawing sections, on the other hand, is a better way to depict vertical distance.
Surveyors employ a variety of tools, such as total stations, GPS receivers, prisms,
3D scanners, radio communicators, digital levels, dumpy levels, and surveying software,
to complete their work successfully and accurately.
b. Geomatics
Geomatics is a professional field as well as an applied science. It involves an
integrated approach to the measurement, analysis, management, and display of
geographic and other spatial data as an applied science. Geomaticians, as a professional
field, have specialized skills, knowledge, and understanding to deliver services that meet
societal needs and contribute to social and political stability, quality of life, and natural
heritage and resource management. Surveying, geography, information systems, land
development and planning, law, and commerce are all areas where geomatics specialists
may be involved in developing, conducting, and managing activities. As the programmed
streams below indicate, geomatics specialists use the latest satellite, laser, acoustic, and
information technology and are constantly branching into new hard areas of specialty.
2. Differentiate plane and geodetic surveying
a. Plane Surveying
Plane surveying is a method of surveying in which the Earth's surface is assumed
to be flat and the curvature of the Earth is ignored.
The plane measurements span only a short distance, and the lines connecting
every two places, mostly on the Earth's surface, are regarded as straight lines, with the
angles between them referred to as plane angles.
When working with plane surveys, you'll need to know about plane geometry and
trigonometry. Plane surveys with a coverage area of up to 260 km2 are an option. It's
worth mentioning that the length difference between the arc and the subtended chord on
the Earth's surface for a span of 18.2 km is only 0.1 m.
b. Geodetic Surveying
Geodetic surveying is a type of surveying that accounts for the Earth's curvature
or spherical structure. The accurate coordinates of points obtained by plane surveying are
provided via geodetic. Geodetic surveys are carried out by the country's survey agency.
This is surveying that takes into account the Earth's curved shape.
A geodetic survey's goal is to determine the exact location on the Earth's surface
of a network of widely dispersed points that will serve as control stations for less precise
surveys.
A curved line is a line that connects two points, and the angles are expected to be
spherical. It is carried out when the field size surpasses 250 hectares. Geodetic surveying
entails choosing two stations (points) that are separated by a large distance.
Astronomy is used to determine the latitude and longitude of these two sites. The
baseline is the line that connects these two points and is accurately determined.
The location of a third station is determined by the angle created between the
baseline's ends. Triangulation is the term for the entire technique. This process is repeated
until all surveyed lands have been mapped.
3. Define and discuss the following:
a. Cadastral Survey
Cadastral surveying is a land surveying field concerned with land ownership
regulations and the delineation of property boundaries. It entails interpreting and advising
on boundary locations, land ownership status, and rights, restrictions, and interests in
property, as well as recording such information for use on plans, maps, and other records;
it also entails the physical delineation of property boundaries and determination of
dimensions, areas, and certain rights associated with properties, whether they are on land,
water, or defined by natural or artificial features.
Cadastral surveys are used to divide land into parcels for ownership under a land
title, as well as to re-establish boundaries of previously surveyed properties to ascertain
the physical extent of ownership or to allow the transfer of the property title.
b. City Surveys
These are surveys of areas within and around a city for the purposes of planning
expansions or improvements, establishing property lines, erecting reference monuments,
determining the physical features and configuration of the land, and generating maps.
The goal of the City Survey was to find out how far the city had progressed in
terms of developing and implementing cycling policies. When producing maps, laying
out plots and new streets, and constructing roadways, pipelines, sewers, and buildings,
these skills are also required, establishing reference points and benchmarks, finding
property lines, and surveying the land's topography.
c. Construction Survey
A construction survey is a survey that shows the locations and markers for
construction activities, as well as the process of evaluating and estimating construction
activities before to or during construction activities.
