Discussion
Consider the following statements about field use of a map.
1. Orienting the sheet lets map and ground be compared directly.
2. Resection fixes the observer's position from bearings to known features.
3. A compass bearing can be plotted on the sheet without correction.
Answer: C
The first two are correct. The third ignores the difference between magnetic and grid north, which must be applied before a field bearing means anything on the sheet. Plotting a raw compass reading puts the line several degrees out.
