“Land surveying basics” is a key phrase in the real estate and construction industry. It forms an integral part of the land development process. But what does it truly entail? For individuals unfamiliar with the subject, land surveying may seem quite complicated. This article seeks to demystify this discipline by breaking down its fundamentals.
So, What is Land Surveying?
To begin with, land surveying is a scientific process of determining three-dimensional positions of points and the distances between them. These points are typically found on the surface of the Earth and are often utilized to define land maps and boundaries for ownership, locations or construction activities. Considered as one of the oldest professions in the world, land surveying dates back to ancient times as people started to establish land ownership.
The Importance of Land Surveying
The importance of “land surveying basics” cannot be overstated. With increasing land costs and the complexity associated with land development, proper land surveying is an absolute necessity. From settling property disputes to road design and construction, land surveys play a pivotal role. They assist in ensuring accurate measurements which facilitate optimal use of space and avoid future disputes.
Land Surveying Techniques
There are a multitude of land surveying techniques available depending on the nature and accuracy required for the task. However, some common techniques among them are Aerial Surveying (used for large scale projects), Topographic Surveys (used to identify and map the contour or terrain features) and Geodetic Surveys (conducted over large areas and with high precision) among others.
Land Surveying Instruments
Land surveying isn’t executed by mere judgement of the naked eye. It requires both skills and usage of appropriate instruments. Some of the most commonly used instruments in modern land surveying include Theodolites (used to measure horizontal and vertical angles), Total Station (an electronic theodolite combined with an electronic distance meter), GPS Receivers (used for precise location determining) and Drones for aerial surveys.
The Process of Surveying
The way towards understanding “land surveying basics” would be incomplete without understanding the process itself. A typical surveying process is divided into three phases: Research and Preparation, Field Work and Plotting and Mapping. Each of these stages involves a set of meticulous steps, and the precision in these steps helps produce an accurate survey.
Conclusion
In essence, land surveying is a technical craft requiring a combination of skill and precision. Though this article presents the basics, there is much more involved in becoming a life-experienced, fully-qualified land surveyor. Nonetheless, understanding “land surveying basics” is a good place to start for anyone interested in building, buying, selling, or generally dealing with real estate.
