A Clearer View Of Surveying

By Carey Bourdier


It may be rare for most people seeking out job opportunities to take an interest on becoming a surveyor although it can be a fascinating profession. Perhaps it is safe to say that people commonly look at surveying as merely intended for measuring and plotting out maps for land but if you become fully oriented with it you'll find that there is a wide array of surveys. Try to sit down and read as much as you can about the different types of surveys and in the end you might find yourself motivated to pursue a career in one area.

For our first type of survey we have the one used for measuring the underwater depth of the Earth like our lake or ocean floors and it is known as Bathymetric survey. For this kind, surveyors primarily measure ocean depth through what you call depth sounding. But an interesting fact is that the older ways to measure underwater depth would have to be through the use of heavy and pre-measured ropes or cables lowered by the side of a ship. Taking an interest into this type of survey should require you to understand bathymetric maps and charts being that accurate and measurable description for a visual presentation in terms of the submerged terrains all over the world. Come to think of it, this is the submerged counterpart of the above water topographic map you know of.

If you want to understand deformation surveys then you ought to know that it is commonly used in ascertaining whether there is movement in an object or infrastructure, the likes of a building. It is understood as the measurement as well as the tracking of any possible alteration in an object's shape or dimension possible caused by stresses due to applied loads. Changes in bedrocks, the increase or decrease in the weight as well as alteration in material properties contribute are factors in consideration which you need to understand if you want to learn about deformation surveys.

Maybe geological maps and geological models would interest you. You can always go for geological surveys and deal with the systematic investigation of the geological make-up on a certain area or land. If so, you will learn how to conduct the traditional walk-over surveys and at the same time do some studies on landforms and outcrops. This is a great option for people who enjoy working outside, as you will be out in the wide open using boreholes and augering in order to acquire information. Also, its geophysical techniques and remote sensing methods would let you do aerial photography and satellite imagery.

Uncovering history is perhaps one good description when it comes to archeological surveys. This type of survey is sort of a field research used by archeologists to collect information about the past human cultures across a particular area. Back then, surveys were not as commonly used when it comes to archeology but it should be noted that through the years it was discovered that it indeed comes with several benefits. And so, archeological surveys came into play more commonly for the purpose of preliminary exercise or in the place of excavation.

Of course surveyors use many tools and you must know what the tools are such as theodolites, inclinometers and still many more optical instruments. For precision in measuring angles in both horizontal and vertical planes, you need these theodolites. As for angles and slopes along with the object's elevation or depression which can be relative to gravity, an inclinometer is going to be your tool. Sights and alidades and other optical instruments also are essential. These days, you also use electronic equipment such as total station or global positioning systems.
