Before
GPS technology was invented, land mapping was manually done by collecting data
from a specific land area. Cartographers had to spend hours to complete maps
back in the day but today, advancement in technology has made a great impact in
making land mapping more time-effective and easier.
Land
surveying involves all activities that record and measure all information in
our physical world as well as the environment. The term is used interchangeably
with Geomatics—a body of science that involves pinpointing the position of
things above and below the surface of the earth. Mapping is a part of the land
surveying process. It uses specialized technology, mathematics and mapping
equipment.
The
role of a land surveyor is to determine and mark different locations on a
certain land. This is used in surveying boundaries of certain real estate
properties in order to find out their specific coordinates. Land surveyors come
up with three-dimensional or 3D positions and distances of angles between them.
Out in
the field, the land surveyor use GPS, aerial/terrestrial scanners or Robotic
Total Solutions to map a certain area of land. They take photos and make
computations. In the office, they use sophisticated software such as Auto CAD to
plan and draft their measurements. They work on a variety of projects that
involve mining exploration, land division, tunnel building, land size
determination and measurement. They are also responsible for providing specific
information about a land to guide the work of architects, land developers and
engineers.
