Surveying techniques actually originated throughout much of the existed history recorded in another time, a place that was known for working out mathematical solutions contributing invaluable knowledge to the world. A past time when the River Nile overflowed, its banks washing out farm boundaries in ancient Egypt. By using simple applications of geometry, boundaries were re-established. The question is how can we be certain of this fact?… Simple. It was discovered and recorded how the nearly perfect square of the north-south orientation of the Great Pyramid of Giza, which was built c. 2700 BC, confirmed the Egyptians’ command of surveying techniques.
What Is Surveying:
It is the combination of science and technique, which allows accurate determination of the terrestrial or the three-dimensional space position of points and the distances and angles between them. Such points are associated with the positions on the surfaces of the earth, however, not exclusively. These positions on the surface of the earth often are used to establish land maps and boundaries for ownership or even governmental purposes. Why is this done? To meet their objective surveyors use the elements of geometry, engineering, mathematics, physics and law.
The Types of Surveys Available:
There are numerous surveys available, each for a different objective. There are a few listed below with brief description:
• ALTA/ACSM Survey:
This type of survey which is frequently shortened to ALTA surveys are often needed for real estate transactions.
• Boundary Survey:
The actual physical extent of property ownership
• Deformation Survey:
This type of survey determines if a >
structure or object is changing shape or moving. The positions of the three-dimensional points which are specific to an object determined once a period of time is allowed to lapse, it is then the positions are measured again and calculated; comparisons of the two sets of positions will then be made.
• Draw Lot:
One lot from a plat is drawn, with any easements and setbacks that may be on it.
• Engineering Surveyors:
This type of survey is associated to engineering design, which often requires geodetic computations beyond the usual civil engineering practise.
• Foundation Surveyors:
This type of survey measures the position of the house prior to it being completed in its build status.
There are many other survey types which are not listed above. It is clear that each survey pronounces a very different aim.
