Surveying Review Advanced 2

Front

What is surveying?

Back

Surveying is the science and art of determining the relative positions of points on, above, or below the surface of the Earth, often using measurements of distance, angles, and elevation.

Front

What are the main types of surveying?

Back

The main types of surveying include land surveying, engineering surveying, hydrographic surveying, and geodetic surveying.

Front

Define 'contour lines' in surveying.

Back

Contour lines are lines drawn on a map connecting points of equal elevation, used to represent the terrain's shape and slope.

Front

What is the purpose of a leveling instrument?

Back

A leveling instrument is used to determine the height of points and to establish a horizontal plane.

Front

Explain the term 'benchmark' in surveying.

Back

A benchmark is a permanent reference point of known elevation used in surveying to measure height.

Front

What is the difference between 'horizontal distance' and 'vertical distance'?

Back

Horizontal distance is the distance measured along a horizontal plane, while vertical distance is the height difference between two points.

Front

What is a total station in surveying?

Back

A total station is an electronic/optical instrument used for surveying that combines the functions of a theodolite and an electronic distance measuring device.

Front

Define 'azimuth' in the context of surveying.

Back

Azimuth is the angle between a reference direction (usually north) and the line to a point, measured in a clockwise direction.

Front

What is the significance of the 'datum' in surveying?

Back

A datum is a reference point or surface from which measurements are made, crucial for ensuring consistency in surveying.

Front

Explain the concept of 'scale' in surveying maps.

Back

Scale is the ratio of a distance on the map to the corresponding distance on the ground, indicating how much the real-world distances have been reduced.
