Define the following terms:a. Elevationb. Datumc. Benchmarkd. Backsighte. Height of Instrumentf. Foresightg. Turning Point

Detail answer given below

Explanation:

Elevation

The elevation is a sketch that shows the front or side of something. A floor plan, on the other hand, shows a space from above, as if looking at the room from the ceiling. Therefore, you can see the top of everything, but you cannot see the front, side, or back of an object. An elevation gives you the opportunity to see everything from the other points of view.

Datum

A reference reference or simply reference is an important part of an object, such as a point, line, plane, hole, set of holes or a pair of surfaces, which serves as a reference to define the geometry of the object and (often) in measuring aspects of real geometry to assess how closely they match the nominal value.

Benchmark

A reference point is a reference point by which something can be measured. In topography, a "reference mark" (two words) is a publication or other permanent mark established at a known elevation that is used as a basis for measuring the elevation of other topographic points.

Back Sight

A view or orientation on a previously established recognition point (other than a closing or control point), taken in the backward direction.

Height of Instrument

A topographic term used in spirit leveling for the height of the line of sight of a leveling instrument on the adopted data, in trigonometric leveling for the height of the center of the theodolite on the ground or station mark, in stadium topography for the height of the center of the transit telescope or telescopic alida on the ground or the mark of the station, and in differential leveling for the height of the line of sight of the telescope on the leveling instrument when the instrument is level.

Foresight

The goal of forecasting is not to predict the future, but to discover the perspectives of many different futures and make decisions today. Therefore, the forecast is based on two premises: that there is no future but many possible futures; and that today it is possible to make decisions that influence future developments.

Turning Point

The terminology of turning point is explained as it is a time when an important change takes place that affects the future of a person or thing.
