Surveying Equipment

When it comes to surveying, land surveyors know that their choice of equipment can be
very important. Surveying is the science of determining the dimensions and contour of
the earth's surface by measuring distance, directions and elevations. It is as old as
recorded civilizations but has come a long way since then. Choosing surveying
equipment is essential for getting proper readings.

Surveying instruments have come along way since the very first surveys were done.
Technology has made doing land surveying easier. It has also given us surveying
instruments that could have only been dreamt of before. This means there are more
options for surveyors to consider so you need to research all options to know what is
best for you.
When it comes to land surveying, it pays to take the time to learn about your options so
you can get the best equipment for your needs. The first step is to know what type of
surveying you will do and the degree of work you're doing. The next step is to learn
what is out there so you know what your choices are.
Some examples of things you might need are:
Laser levels - This will shoot a laser beam that tracks elevation. It is also a handy tool
when doing construction surveys. There are two types of laser levels available. These
are the single and rotating-beam lasers. The single rotating-beam laser will offer a more
linear approach to land surveys where a rotating-beam laser can be used in open areas
to create a wider survey.

Theodolites - These are most commonly used for horizontal and vertical angling. They
can also determine elevation and height.

GPS equipment - Probably the best invention for conducting true surveys is the GPS or
Global Positioning System equipment. This system uses satellites to conduct the surveys.
The unit makes contact with the satellite which transmits a signal. It does this by taking
the variations in height between two points along with the distance and directions.

Measurement equipment - A measuring wheel is the most common type of
measurement equipment. This method works by rolling the wheel along the desired
measurement and counting the revolutions of the wheel. The counting is done by
having an odometer on it that records the revolutions.

Tripod equipment - Having a stable tripod is essential when taking surveys. If the tripod
moves, it must be reset and the survey repeated. The material that the tripod is made of
can also affect a survey. Wood and aluminum can become water logged and can change
the results of the survey while fiberglass is heavy and cumbersome. It can come down to
personal preference when choosing the right tripod equipment for you.
