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. Hydrographic Survey
