Land Surveys & Their Importance

July 7, 2010 | Comments Off

It is the delicate method of determining sensitive information like the 2D or 3D position of all the points, their distances & the angles existing between them in a given property. These data are used later by surveyors to build up boundaries & land maps which can be referred to solve land ownership issues & construct private to government projects. The land surveys play a crucial role in the smooth running of projects including from the environment & construction sector. With the rapid development in technology the traditional land surveys have given rise to several other new varieties of surveys that can successfully measure the water & air present above & below the given piece of land.

The topographic surveys, building surveys, boundary surveys, construction surveys, location surveys & ALTA/ACSM surveys are some of the most popular surveys conducted these days. An ALTA survey is a very detailed survey covering all the elements of mortgage surveys & topographic surveys in it. These surveys are mainly sought upon by lending institutions. The ALTA survey of a commercial property needs to confirm a set of mapping & surveying standards as devised by the ATLA/ACSM together. The Alta survey of industrial properties strictly adhering to the ALTA/ACSM standards is surely going to bring them better results in the form of ROI.

In view of the growing demand for building extension or conversion plans, building surveys are becoming more prevalent. They are the expensive survey type which are usually recommended for buildings that are already having lots of extensions or alterations or will undergo massive renovation or alteration in nearby future. Those who want to keep pictorial record of their property after a long period of alterations prefer to go for building surveys.

Similar to their name, boundary surveys are carried out to demarcate the original boundaries of a given piece of land or property. The surveyor takes into account the previously recorded markers along with the new improvements on the land while preparing the true boundary lines of a property.

The topographical surveys are the ideal way to distinct natural & artificial developments on a site. These surveys value a lot in both government & private projects. The architects & engineers use these maps as an important tool to aid in the designing or development of a site. The topographic maps help in finding fences, elevations, land contours, trees streams, buildings & other improvements on a piece of plot.

All kind of land surveys find maximum application in architectural, electrical & construction industry. The land surveys are regarded as handy tools of reference from conception & planning phases to production & maintenance thereafter.

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.
