Land Surveying is the science and art of locating points below, above and on the earth’s surface and relating those particular points to a certain common reference system.
What is land surveying?
We use surveying to ensure that order is maintained in the physical world we live in. Surveying is use in land development projects starting from the planning and designing phase’s right through to the final stages of construction of landscaping, utilities and roads etc.
Survey projects also include professionals from fields such as architecture, geology& planning as well as engineering and all these experts work in tandem to ensure the smooth working of the project.Surveyors are the very first professionals on construction sites, assessing, measuring and mapping the land.
All these measurements are later used by architects to learn more about and make the most of the landscape when designing structures; the engineers plan the structures safely and accurately, ensuring that the buildings not only fit into the landscape but that it is feasible to construct them.
What is a land surveyor?
A land surveyor works with builders, architects, and engineers to produce very precise descriptions (maps and surveys) of the earth’s surface features. These professionals handle a wide range of tasks such as construction staking, topographic mapping and boundary surveying.
A land surveyor will work on the field as well as in an office. These professionals work on a range projects from mining exploration and land subdivision, to major construction as well as tunnel building. They have the expertise to determine and measure land size. Aside from this they provide information and advice that helps developers, architects and engineers in their work.
There are different types of surveyors; some professionals prepare survey plots and maps and determine property boundaries. A registered surveyor is generally referred to as a cadastral surveyor as they are involved in maintaining the cadaster-locating & marking of the property boundaries.Boundary surveying is one of the first and most important tasks that a land surveyor performs. This survey is recommended before purchasing, improving, subdividing or constructing on land.
The land surveyor will conduct a detailed survey on the land before any of these activities to help avoid the hassle and expense of defending lawsuits, resolving any boundary disputes or moving buildings etc.Surveyors provide detailed documentation of legal property lines which helps determine the exact location of construction and real estate projects. For instance, when any residential commercial structure is bought or sold, it might have to be surveyed to avoid any boundary disputes.
They help determine the locationof the legalland ownership lines which goes a long wayin minimizing the risk of real estate transactions. Mostlending and title corporations use theservicesof a land surveyor to reduce therisk of their deals. In the construction phase, a surveyor determines the exact location of roads/structures and the appropriate depths for the foundations of buildings. These surveys also show changes to the property lines and indicate any potential restrictions on that property, including what can be constructed on it and what the size of the structure can be.

Duties that a land surveyor performs
Land surveying covers a large variety of activities and a surveyor can be involved in one or moreof these in tandem with professionals such as architects and engineers:
• Providingthe spatial infrastructure required to support an effective land tenure &cadastral system
• Determining, locating &defining the boundaries of private and public land (including national boundaries)
• Arbitrating on disputes over boundary location
• Interpreting anomalies in a specificcadaster
• Designing &establishing detailed spatial reference systems to ensure a homogeneous framework for land information and geographic systems
• Collecting, analyzing& managing geographic data as well as designing, administering and establishing geographic and land information systems
• Providing advice and information related to property and its immediateenvironment, to help determine the most sustainable land development and use
• Assessing all the potential benefits or downsidesthat could arise from property development; advising clients and the governments as appropriate
• Contributing to the development& management of rural and urban properties by advising, planning, negotiating & implementing procedures
• Estimating, planning, measuring, designing and managing construction projects and applying effective financial control
• Producing maps, plans, databases, files, models, reports and charts for clients.
Systems and tools that land surveyors use
Today, a large number of tools and software are used in the on-field and in-office land surveying work. These tools help provide more accurate measurements and data and have made the landsurveying job less laborious.
• Traditional manual distancing tools have been replaced by fully-robotic ones; these are called Robotic Total Stations (Theodolites)
• Satellite technology is used for location mapping
• Laser-based, calibrated and GPS-enabled chronometers
• Astronomically-capable devices
• Aerial and terrestrial scanners for mapping areas
• Aerial canning devices for taking photos as evidence and for making computations
• In the office, land surveyors use sophisticated software, such as AutoCADfor draftingplans and mapping the onsite measurements
