The first step
to conducting
a proper land survey is gathering the right equipment for the job. No matter whether you&#re measuring
a property line for
a fence, vertical lines for
a skyscraper or mapping
a riverbed prior
to a dredging operation, it is vital
to have the right equipment for the job.

a comparative analysis of the various prism sets available through SouthernPhoto.com.
The primary
tool a land surveyor uses is
a total station. This device sits atop
a tripod and emits an infrared beam that is intercepted by
a prism fixed on top of
a pole. Proper land surveys usually require two people
to operate the equipment: one
to hold the pole carrying the prism, and one
to operate the total station and collect data from Global Positioning Systems. When the data is collected and entered into
a computer,
a specialized program can calculate the area of survey
to within
a few millimeters.
Surveyors have several options when choosing
a prism set
to compliment their total station.
The CST single prism assembly comes encased in
a lightweight but rugged polycarbonate container, so it won&#t break easily in the field. The CST model is used with
a brightly painted red and white sighting pole
to allow for quick sighting in long-distance surveys.
The Seco Tilting Triple Prism assembly can hold one, two or three prisms at once, allowing for even more
accurate measurements than
a single prism device. It is encased in orange polycarbonate with metal inserts and an
aluminum yoke, which make this
a very sturdy device that can stand up
to the elements and will last for
years with proper care. The prism assembly is compatible with most screw-in prisms, and it comes equipped with
a peep sight that allows the surveyor
to accurately point the holder toward the infrared beam.
http://www.southernphoto.com/view_manu_items.asp?CTGRY=Survey%20and%20Construct ion%20%20Instr./GPS&manu=TOP[Topcon makes many surveying
products including data collectors and total stations, so it&#s no surprise that this company offers several different options for prisms as well. The Topcon prism assembly comes encased in heavy-duty plastic
to offset damage if dropped or jostled. The zero-constant prism features precision-ground glass with
a 60 millimeter effective diameter. It also comes equipped with
a prism holder for long-distance horizontal measurements. The Topcon prism features
a striped sighting pole for easy spotting by the data collector. This model
does not tilt, but it can be inverted
to house
a 30 millimeter prism.
The Sokkia Deluxe Pentaprism offers
a view of 90 degrees off the surveyor&#s line of sight. This hand-held device is housed in
a black anodized shell with
a satin finish and comes with
a carrying case that clips onto
a belt. The palm grip
barrel is
3 inches long with
a 1.4 inch diameter, and extends
to 4 inches
to enable sighting.
