To understand land surveying, one has to know that surveying refers to the measurement and mapping of our surrounding environment using mathematics, specialised technology and equipment. Surveyors measure just about anything on the land, in the sky or on the ocean bed. Even polar ice-caps are measurable!
What Is The Job For The Surveyors?
Both office and field work are the staple for surveyors. While out under the sun, they use latest technology such as high order GPS, robotic total stations (theodolites), aerial and terrestrial scanners to map an area, make computations and take photos as evidence.
On the other hand, the professionals from surveying companies use sophisticated software, such as auto-cad and draft plans to map the on-site measurements. Surveyors work on a diverse variety of projects from land subdivision to major construction. Being experts in determining land size and measurement, they also work as advisors for engineers, architects and developers.
Roots Of Surveying:
According to history, surveying is not a new profession and has been around for quite a long time. The first land surveys find their roots in Egypt, nearly 3,000 years ago. Egyptian surveyors subdivided the fertile land around the river Nile and worked to re-make the land after the annual flooding of Nile.
The early settlement of Australia also involved surveying. Famous explorers like Burke and Wills had a surveying background. Their work, defining property boundaries in the city and the country allowed the land to be settled. Back then, surveyors used primitive technology including chains and steel bands, which made their measurements difficult to record and often required the use of logarithmic tables and slide rulers. Now the scenario has changed from Perth to Peru and every place around the globe. Modern technology has made surveying more enriched and efficient.
What Is The Need For All The Hard Work?
Surveying plays an important role in ensuring order in the physical world around us. In the realm of land development, surveying is necessary for planning and designing of land subdivisions through the final construction of roads, utilities and landscaping.
Surveyors work closely with their peers in the fields of engineering, architecture, geology and planning. Their range of activities complement the work of civil engineers. Surveyors are the first people to examine and measure any construction site. These primary measurements are then used by architects to understand and make the most of the unique landscape when designing, and by engineers to plan structures accurately and safely. As such, surveyors do not only ensure buildings fit with the landscape, but also approve the proposed construction.
