The Type of Land Surveying Equipment That You Will Need
Land surveying is a vital part of the design and construction process of various aspects like roads, buildings, etc. Land surveys are done 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 much more.
Land surveys should be carried out with keen details to ensure that the best results are achieved. Surveyors should, thus, make use of certain equipment which may include:
GPS equipment- It is used to take variations in height between two points, their distance and directions by contacting the satellite.
Tripod equipment- They are used to back other surveying instruments like theodolites, total stations, levels or transits. They should be unwavering while in use because a slight change in position requires the repeat of a survey. Their accuracy is affected by water, making the choice of their material very critical.
Measurement equipment- A measuring wheel is the most commonly used. It is usually revolved along a particular distance while an odometer counts its revolutions.
Theodolites- They are used for horizontal and vertical angling, and they can also determine elevation and height.
Laser levels – They are used to shoot beams of laser light that tracks elevation. They are of different types due to the many tasks that are carried out during construction. They are either self-level or manual. Self-level lasers are able to find their own level without being adjusted at all, while manual lasers require being adjusted.
Laser receivers- They are used together with laser levels to work on greater spaces that require being assessed. They pick up the beams of light from the laser levels and make a sound once the right level has been achieved. They are helpful to make the use of laser levels outside and on very sunny days easier.
Single or dual grade lasers- They are utilized when slopes require being assessed. 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.
