A horizontal angle is the difference between two readings from the ho-
rizontal circle. However, a reading from one of the circles is also often
described as an angle.
Distance from the center of the telescope to the point at which the laser
beam strikes the target surface
The horizontal distance derived from the measured slope distance.
The rotatable center part of the total station is known as the alidade.
This part usually carries the control panel, bubble levels for leveling and,
inside, the horizontal circle.
The tool stands on the tribrach which, for example, can be mounted on a
tripod.
The tribrach has three points of contact which can be adjusted vertically
by adjusting screws.
This is the point at which the tool is set up - usually over a point marked
on the ground.
The height of the point on the ground at the tool station (above a refer-
ence height).
The height from the point on the ground or floor to the center of the tele-
scope.
The distance from the center of the reflector to the tip of the reflector
rod.
The target point used in conjunction with the tool station to determine
the horizontal reference direction for the horizontal angle measurement.
Electronic Distance Measurer (laser distancer / range meter).
In a typical surveying coordinate system this value refers to the east-
west direction.
In a typical surveying coordinate system this value refers to the north-
south direction.
This is the term used to describe a longitudinal measurement along a
building control line or other reference line.
This is the term used for a distance at right angles to a control line or
other reference line.
Many values are referred to as heights.
A height is a vertical distance from a reference point or reference surface.
