In plane table surveying, the radiation method is most suitable when the details are located:
Correct answer: A. Around one accessible station
- A. Around one accessible station
- B. Only on the opposite side of an obstacle
- C. Along a long closed traverse
- D. At points with unknown magnetic declination
Explanation
In radiation, rays are drawn from one occupied plane table station to the detail points, and distances are measured from that station. It is therefore convenient when the surrounding details are visible and accessible from one point.

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.
