SURVEYING AND SURVEY CATEGORIES
Definition:-
In
general, surveying
is performed to determine the relative location or positioning of points on or
near the earth's surface. More
specifically, surveying is the science of making measurements, relative to known
or assumed datum’s and standards, and applying the principles of mathematics to
such measurements to determine existing or future horizontal and vertical
position, from area, magnitude, boundaries, and extent of land parcels and
topographical features.
Survey
categories:-
1. Geodetic Surveys - Surveys, which establish control networks on a mathematical
datum so that measurements will reflect the curved (ellipsoidal) shape of the
earth.
2. Land Surveys - Surveys which include retracement
of existing land ownership boundaries or the creation of new boundaries.
3. Engineering Surveys - Surveys performed for the location, design,
construction, maintenance and operation of engineering projects.
4. Construction Surveys - Surveys which establish stakes in the ground, and
other like reference points, at known horizontal and vertical positions to
define location and size of each component of the facility to be constructed,
enable inspection of contract items, and serve as a basis of payment for work.
5. Cartographic Surveys - Map making from original survey is called
Cartographic survey.
