Land Surveying Equipment That Are Essential for Surveys
Land surveys are fundamental for the design and construction of particular aspects like roads, buildings, etc. They are carried out to mark boundaries, map the topography of land, create elevations for buildings to ward off floods, to ascertain that buildings have been constructed as per particular recommendations, to map river bottoms for dredging, layout photo control for aerial photography, map the layout of tunnels, airports, and so on.
Land survey activities must be done with a high degree of accuracy to attain excellent results. Surveyors require special equipment to execute their tasks and they may include the following:
GPS equipment- It normally contacts the satellite to record the variations in height between two points, as well as their distance and directions.
Tripod equipment- Tripods are used to support surveying instruments such as theodolites, total stations, levels or transits. It ought to be stable because when it is moved, it must be reset and a survey repeated. Tripod equipment can get waterlogged and produce inaccurate results, so their material should be carefully selected.
Measurement equipment- The most common of them all is the measuring wheel. It usually has an odometer attached to it that records the number of revolutions a wheel takes as it is rolled down a particular distance.
Theodolites- They are used to realize horizontal and vertical angles, elevation and height.
Laser levels- They give off beams of laser light that is used to determine elevation. They are of different types due to the many tasks that are carried out during construction. They can be either manual or self-level. Self-level lasers find their own levels independently, while manual lasers require being adjusted while in use.
Laser receivers- They are used together with laser levels to work on greater spaces that require being assessed. They pick up beams from the laser levels and adjust their height until the right level has been found, at which point the receiver emits a constant sound. They are helpful to make the use of laser levels outside and on very sunny days easier.
Single or dual grade lasers- They are used to measure and define the gradient of a slope. The single grade laser only calculates gradient for one particular plane, while dual grade lasers can calculate the gradient of two planes at once.
Rotating and straight line lasers- Rotating lasers give off beams of laser light from a beacon that evaluate an area across 360 degrees, while straight line lasers are used to generate crosses or plumb lines.
Pipe lasers- They are used during the installation of new pipes, drains or sewers. Pipe lasers are used to align pipes and grade them in line with each other, one after the other.
