GPSC AE (Class 1 & 2) – 2019
⭕ A. orienting the plane table
⭕ B. centering the table
⭕ C. finding the line joining the two points
⭕ D. solving a triangle
📚 Explanation:
The two-point problem in plane tabling involves orienting the plane table correctly with respect to the field.
🔹 This is done by locating two known points on the field and plotting them on the table.
🔹 Orienting the table ensures accurate alignment and direction for subsequent surveying.
🔹 The process helps maintain the correct bearing and scale throughout the survey.
