Surveying: What You Need To Know

While many people may take an interest on several different careers, pursuing one in the field of surveying may present you with a truly interesting path. Contrary to most common notions about surveying, the task of surveyors is not limited to land surveying and, in fact, there are many different and important surveying career options and different kinds of surveys. Perhaps if one would know some of them, an interest could be sparked to set one up for a very rewarding career in surveying.


It should be good for you to know the first type which is simply defined as the survey conducted for the purpose of measuring the likes of lake or ocean floors – the bathymetric survey. Fundamentally, in conducting bathymetric surveys for ocean depth it calls for depth sounding. An interesting fact is that back in the day, surveyors use pre-measured heavy ropes or cables which they drop by the ship’s side for measuring underwater depth. Perhaps if you have an interest in this type you should familiarize yourself with bathymetric maps and charts being this type’s visual presentation of an accurate and measurable description when it comes to the submerged terrains in the world. If you know that a topographic map is that visual presentation for above water, then you should know that this is the submerged version of the said map.


The deformation survey is the type concerned in determining whether there is movement in a particular object of say, a building. Surveyors here come to measure or track possible changes in the shape or dimension of the object in case there are loads applied and cause some kind of stress. You also need to learn about factors like changes in bedrocks or changes in material properties, which might include the decrease or increase or decrease in the weight of these materials.


Are you interested in learning how to make geological maps and models? Then understand geological surveys as this is concerned with systematically investigating what is beneath a given piece of ground. Here you will learn how to do the traditional walk-over surveys as well as conducting studies for outcrops and landforms. This could very well define “outdoor fun” in this side of profession given the required use of machine driven boreholes, or perhaps hand augering when using intrusive methods. You will also deal with aerial photography and satellite imagery for geophysical techniques and remote sensing methods.


If history is interesting for you, go for archeological surveys. Archeologists use this type for their field research and collect data regarding past human cultures in a given area or place. Archeological surveys are exciting because those who create these surveys are truly helping to uncover clues about past civilizations. This is an excellent vocation for those who enjoy history, cartography and surveying.


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.
