A level
Land-surface datum is a datum plane that is approximately at land surface at each well. If known, the elevation of the land-surface datum above sea level is given... Datum: any level surface, line, or point used as a reference in measuring elevations.
a bubble tube of a level has a sensitivence of 20" per 2 mm division. Find the error in the reading on the staff held at a distance of 100 mm from the level when the bubble is deflected by two division from the centre.
Water levels in surveying refer to a tool used to establish a horizontal line of sight for measuring elevations and heights. It consists of a long tube filled with water, with a bubble that moves to indicate when the tube is perfectly horizontal. This allows surveyors to accurately measure differences in height between points.
Datum surfaces are reference surfaces used in engineering and manufacturing to establish a common point for measurements and alignments. They provide a consistent and uniform starting point for design and quality control processes. Examples include planes, lines, and points from which other measurements are made.
A seismometer is the instrument used to measure horizontal movements along faults. It records the seismic waves generated by these movements.
The horizontal datum used by GPS is the World Geodetic System 1984 (WGS 84). It provides a consistent reference frame for defining positions on the Earth's surface.
You Use A Lever CORRECTION: You use a LeveL, not a LeveR. LEVEL!

When utilizing the DAGR, the field that automatically displays the waypoint datum is the "Dat" field, which stands for datum. The datum represents the reference point used to define the location coordinates of the waypoint.
A spirit level or bubble level is a tool commonly used to determine if a structure is perfectly horizontal. It contains a liquid-filled tube with an air bubble that moves to the center if the surface is level. This makes it easy to adjust and ensure that the structure is perfectly horizontal.

The true singular form of data is "datum." However, it's so rarely used, that people just assume that "data" is singular form.
The basic angle from the datum may be any amount except 90 degrees.
Above Ordnance Datum is a reference elevation used in surveying that is based on the mean sea level. It provides a standard benchmark for measuring height or altitude across different locations. This datum is commonly used in the UK and other countries for mapping and surveying purposes.
Yes, "datum" is the singular form of "data." However, in common usage, "data" is often used as both singular and plural.
the tool used to find the width of a pencil is a ruler. But use the centimeter side of it for the width only!!
a scale or a balance
