UPRVUNL AE – 2015
⭕ A. It avoids missing of any measurement required for plotting
⭕ B. It is an accurate method
⭕ C. It is not to be used for locating main stations accurately
⭕ D. It is commonly used for filing details in small or medium scale mapping
📚 Explanation:
Plane table surveying is a method where both observations and plotting are done directly in the field. While it helps prevent missing measurements, it is not highly accurate.
🔹 It is commonly used for small-scale or medium-scale surveys and mapping of field details.
🔹 It should not be used for determining exact positions of main stations.
🔹 Therefore, the wrong statement is: "It is an accurate method".

👉 Therefore, the correct answer is: B. It is an accurate method
Key Features of Plane Table Surveying:
- Used for immediate field plotting during survey
- Not suitable for high-precision work
- Good for topographic and small/medium scale maps
- Prevents omission of field measurements
- Easy to carry out and inexpensive
