When using a Total Station, you measure the slope distance between the instrument and your target and calculate the angular difference from the target to the mirrored target. Remember, the mirrored target, which you place directly under the point you're measuring, should have a known height for this calculation. Surprisingly, the height of your Total Station does not need to be part of this equation, which simplifies your setup.
Even when the ground between your Total Station and the target has a significant slope, the instrument's internals adapt to provide a correct elevation calculation. Every measure you take can be stored in the device's memory and later transferred to a personal computer, offering a streamlined way to handle and analyze the data you collect.
Understanding the intricacies of your Total Station is critical to its application in the field. It's not just about operating the instrument; it's about leveraging its full potential to gather accurate topo-geodetic information for your critical projects. This involves not only the proper setup but also a keen understanding of the environmental variables that might affect your readings.
Total Stations operate by integrating electronic distance measurement (EDM) technology with the precision of a theodolite. When you're attempting to measure elevation, your Total Station plays a pivotal role. It measures slant distances, horizontal and vertical angles, and then calculates the elevations of various points in relation to its position. This technology is intricate, using trigonometry and triangulation to calculate coordinates – X (northing), Y (easting), and Z (elevation).
Robotic Total Stations have taken a quantum leap forward, offering you automated benefits over traditional models. With a robotic system, you can singlehandedly control the device via remote control, while the instrument automatically targets and follows a prism attached to a pole that you hold at each survey point.
