What Is A Total Station And How Does It Work?
The terms land surveying and surveying often lead to confusion because they are not always interchangeable. The use of the word survey has many meanings in a variety of contexts. In this article, we will explain the differences between land surveying and surveying as well as LIDAR (Light Detection And Ranging) and sonar (Sound Navigation And Ranging).
Understanding LIDAR
LIDAR stands for Light Detection and Ranging. It is a remote sensing technology that uses light in the form of a pulsed laser to measure distance. The time it takes for the laser pulse to travel from the sensor to the target and back is used to calculate the distance. LIDAR can be used to create highly accurate 3D maps of an area.
Total stations are surveying instruments that combine electronic Distance Measurement (EDM) with an angle measurement system to allow for precise measurements to be taken of both horizontal and vertical distances.
Total stations are used in a variety of surveying applications, including topographic surveys, boundary surveys, cadastral surveys, as well as construction stake-out and volume calculations.
How does a total station work?
A total station consists of an EDM instrument, a theodolite, and a data recorder. The EDM instrument emits a laser beam that reflects off the target and back to the sensor. The time it takes for the pulse to travel from the sensor to the target and back is used to calculate the distance between them. This distance information is then fed into the theodolite, which is used to take measurements of angles
What is LIDAR used for?
LIDAR is most commonly used in airborne mapping applications, and has a wide variety of other uses as well. It can be used to measure the size, shape, and topography of objects, as well as to measure distance and calculate coordinates. It can also be used to create three-dimensional models of objects or landscapes.
How does it work?
A total station is a surveying instrument that is used to measure both horizontal and vertical angles, as well as distance. It is typically used in construction and engineering projects to help ensure that buildings are being constructed according to plans.
Total stations work by sending out a laser beam that reflects off of objects and then measuring the angle of reflection and the distance from the instrument to the object. This information can then be used to create a 3D model of the area being surveyed.
Total stations are highly accurate and can be used to survey large areas quickly. They are also relatively easy to use, making them a popular choice for many surveying applications.
