The Basics 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.

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.

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.

Anyone interested in uncovering history should choose archaeology and archeological surveys. You should know that archeologists find this highly important in gathering information with regards to the old cultures of man across a chosen area to cover. Actually, the past regard surveys to be rather uncommon however as time went on it was found out that surveying indeed has its benefits. With that, archeological surveys became a regular part in ensuring preliminary requirements and sometimes put in place of excavation.

For you to finally become a full-pledged surveyor, you need to be acquainted with tools like the theodolites, inclinometers and several other optical instruments. The theodolite is that precision instrument used to measure angles, whether in the horizontal or vertical plane. Inclinometers measure angles or slopes as well as an object's elevation or depression relative to gravity. Be familiar with optical instruments like sights and alidade as well. At present, instruments come with more modern intervention such as the GPS and the EDMD to make surveying faster and easier.
