In chain surveying, ranging is the operation of:
Correct answer: C. Locating intermediate points on a straight survey line
- A. Measuring the angle between two lines
- B. Determining the elevation of a station
- C. Locating intermediate points on a straight survey line
- D. Calculating the area of a survey plot
Explanation
Ranging means establishing intermediate points so that they lie on the straight line joining two end stations. Chaining or taping then measures the distance along this aligned line.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
