Many of you may not be aware that land surveying is widely acknowledged as the worlds second-oldest profession. Land survey, simply stated, is the art and science of measuring and mapping land. While the entire scope of land survey is vast, it all eventually means where people's land boundaries are located. Land surveys can be critical for building railroads, skyscrapers, airports, bridges etc. Land owners can not put up fences around their yards without exactly knowing the boundaries.
Land survey is a vital part of the design and construction process and qualified surveyors conduct boundary surveys to let the clients know the exact location of their property. They map the topography of land for purposes of engineering design, create elevations of buildings to ward off floods, perform title surveys to facilitate real estate dealings and certify that structures are built according to approved design. They also map river bottoms for dredging purposes, lay out photo control for aerial photography and write legal documents to delineate pieces of property, map layout for tunnels, roads, airports, pipelines, underground cables and railroads, and help split up properties into new lots.
Global positioning System is a tool used by land surveyors for precise positioning of points. It functions through satellites which send out signals to the receiver mounted on the tripod of the surveyor. The receiver then transmits those signals to the data collector of the surveyor that stores the data. Surveyors will thereafter download the data into the computer, and the computer software lets know from the data the exact position of point within a few millimeters.
As already stated, the basic duty of the field surveyor is to measure, map, and observe. The key tool they use for these purposes is called total station. It comprises of a distance meter for measuring distances and a theodolite for measuring angles. Land surveyors derive elevations with the aid of total station by using geometry and measuring the angles and distances and by Global Positioning System by intersecting vectors from satellites in space.

It is the responsibility of the land surveyors to report their work to the office, who in turn will pass the results to the client. If the site is a construction site, then the office will coordinate it with the contractor.
Land surveyors, to succeed, should have the required knowledge about zoning regulations, building regulations, planning regulations, health policies, wetland regulations and general land use codes. They must be able to apply various techniques and current technologies to measure the land.
If you are a well qualified and adequately experienced land surveyor desiring to start your own land surveying business, then you need to provide high quality of service. It is also essential to have modern surveying equipment, computers, laser and access satellite technology, to successfully compete and survive as a successful surveying venture in today scenario.
o The land surveying business to be efficient, should lay stress on proper coordination between the surveying done in the field and the head office staff who are responsible for the work.
o There should be at least one professional land surveyor for 3 field crews for the supervision to be effective.
o Proper technical and operational support and guidance must be provided to the different teams working on surveying assignments.
o It is critically important that all land surveying work conform to technical and accuracy standards.
o Maintain regular rapport with the customers and provide them with updated information.
o There should be regular orientation programs for surveyors on new surveying technology including latest trends in surveying so that the surveyors become more efficient and increase productivity.
