# How is total station elevation calculated?

## How is total station elevation calculated?

Determining elevations Carefully level the total station, first using the bullseye level and the tripod legs and then using bubble level and the leveling knobs on the base of the total station. Rotate the telescope through horizontal. If the station is not level, a b will appear in the vertical angle (V) display.

What can be collected from total station survey?

A total station is an optical instrument commonly used in construction, surveying and civil engineering. It is useful for measuring horizontal angles, vertical angles and distance — it does this by analyzing the slope between itself and a specific point.

How is total station survey done?

A total station is an optical surveying instrument that uses electronics to calculate angles and distances. It combines the functions of a theodolite with that of a transit level and electronic distance meter (EDM).

### What is the principle of total station?

Reflectorless total stations can measure distances to any object that is reasonably light in color, to a few hundred meters. Principle: Given the co-ordinate of the instrument position and bearing of a backward station the co-ordinates of any other point can be computed.

Can a total station measure height?

From the “MEAS” menu select “Menu” > “REM” and then [OBS] (Figure 2) to measure the slope distance (S in Figure 1). Then unlock the vertical clamp and sight in the top of the building corner and re-lock the vertical clamp. Select [REM] (Figure 2) from the function key menu and write down the calculated height (meters).

What is RDM in total station?

Total station survey involves 3D coordinate measurement and remote distance measurement (RDM). A machine equipped with measurement application software is used to facilitate 3D coordinate measurement, resection, edge measurement, and other measurement processes.

#### What is the use of Dist button of total station?

This The Total Station has the ability to display the straight line distance between the last two throws (P1 and P2). Press the [DIST] button to display the straight line distance beteen the last two throws (P-P). For our task and a measurement official, that information is unnecessary.

What makes up a total station in surveying?

The total station A total station consists of a theodolite with a built-in distance meter (distancer), and so it can measure angles and distances at the same time. Today’s electronic total stations all have an opto-electronic distance meter (EDM) and electronic angle scanning.

How to calculate the distance of a total station?

Set the instrument to a known point. Enter the coordinates of the point. Turn the total station until the horizontal circle reads zero. Position the reflector to where it lines up with point P. Measure the distance (which will be calculated and displayed automatically).

## Which is a part of the total station?

An essential component of the total station is Electronic Distance Measuring (EDM) which is responsible for the distance measurement. The measuring range of the EDM can vary from 2.8km to 4.2km. A typical EDM is capable of measuring the distance with an accuracy ranging between 5mm to 10mm per km of measurement.

Which is better total station or theodolite survey?

Theodolites have been around for centuries, but total stations are like better mousetraps. Not only are they more accurate over long distances, but they can also allow you to digitally measure and record specific survey points that you can download to a computer for processing.
