Land Survey-art Of Organizing Land

May 5, 2011 | Comments Off

Land Survey-It is a technique and science of defining three dimensional points and the angles and distances between them. It is known as the second oldest profession in India. It is the essential art of measuring and mapping the land.

Without the use of land survey railroads could not be built, skyscrapers could not be erected, and individuals could not put fences around their yard. This is the vital part of design and construction process. Surveyors mark the boundaries of land and plan and organize the development of property. We deal with lot of issues in our life but the three universal issues are families, health and rights to our land.
Land Survey is performed to tell people where their property is, to establish elevations of sites for flood insurance, to perform title surveys of real estate transactions, lay out buildings etc.

These points are usually on earth surface. In U.S Land Survey under Public Land Survey System (PLSS) is an area making a township. Elements used for surveying are Geometry, Trigonometry, Mathematics; Law etc.It has been an important element of in the development of piece of land. It is planned and required in almost every form of construction. For measuring the are measuring tapes were used which were made of steel or invar, To measure horizontal distances these tapes were set according to temperature to reduce sagging or slack.

As newer techniques are getting invented so the systems of surveying a piece of land. It is making use of various technologies that are used for doing land survey such as GPS systems and other development models. Of course today land surveying is used for many other purposes too. When river Nile overflowed its banks washing out the existing boundaries and farms then surveyors re-established the boundaries through
simple geometrical concepts. Roman Emperors are the great example of civilization known for its land surveying powers.

Techniques used:
Global positioning System-(GPS) Tool used for precise positioning of points. It operates through

satellites where the receiver gets the signal which in turn transmits the signal to data collector.
Traditional Total Station Surveying-Primary function is to measure, map and observe.
Leveling and 3D surveying-In this we calculate the difference between two points in ground.

Land surveys

A Land survey is the science of measuring lines and area of a given parcel or tract of land. Land surveys are not always simple and easy. It often requires many steps to determine the boundaries of a given parcel. We have included an article which gives a little more information on the subject. We hope you enjoy!

Several Aspects of SurveyingSurveying is the process of taking measurements of feature on and occasionally above and below the earth’s surface to determine their relative positions. It is a science of accurately determining the terrestrial position of points and the distances and angles between them. The practice may be more precisely described as land surveying to distinguish it from other forms of surveying like building surveying or quantity surveying.

The process of land and site survey, survey restricted typically to smaller areas of lands in comparison to land surveying, is important for purposes like:

Mapping, to establish land maps from knowledge of geographical features of the land,

Ownership issues, to establish boundaries and establish ownership over land masses,

Resolving disputes and encroachment issues over land,

New construction like buildings, marking off building areas,

Assess the archaeological sites in a landscape,

Mapping features of the bed of a water body,

Determining the soil types and properties of the soil cover,

Governmental purposes

Of the divisions within land surveys, engineering surveying and topographic surveying (representation of land features) are typically relevant to site survey while geodetic surveying (accounting for the Earth’s curvature) is relevant to survey of huge chunks of land masses.

The several methods involved in land surveys are described below:

1.For determining distances: Measuring of the areas with iron chains, steel and invar tapes taking into consideration horizontal and slope areas.

2.For determining angles: Use of compasses bearing magnets, scribed discs, telescopes with reticles.

3.For measuring heights: Use of altimeter or barometer using air pressure as indication of height

4.Global Positioning System (GPS): Advent of the technology has given rise to estimation of elevation derived with sophisticated satellite receivers.

5.Triangulation: With the method, which has outdated GPS, distances, elevations and directions between objects at great distance from one another can be determined with reasonable accuracy.

The set of tools or instruments needed for land surveys have not changed much over the years. Only they has evolved to provide greater accuracy. Apart from the tapes, chains and compasses, some of the equipments that are used in the survey of lands are: theodolite, tripod, electronic distance measurement device (EDM), set up for satellite positioning system for working of GPS, total robotic stations (in conjunction with theodolite), etc.

The land surveyors, who are typically engineering consultants, use elements of geometry, engineering, trigonometry, mathematics, physics and law in their work of surveys. Engineering, especially civil engineering, depends heavily on surveyors. The consultants establish the boundaries of legal descriptions whenever roads, railways, bridges, reservoirs, sustaining wall, buildings are to be built. They also provide advice and data for geographical information systems (GIS) which are computer databases that contain data on land features and boundaries marked in the land.

Though it may seem to be the work of a meticulous engineer who puts together the two and two to make a four, the work in land surveys involve a great amount of art. Some land masses may have problem like improper boundaries and miscalculations, while some may have been created from multiple divisions. The art in the matter lies in the fact that the surveyor has to put together the bits and pieces in solving a puzzle that remains hidden to naked eyes.
