Arrange the following sequential steps involved in conducting a chain survey fieldwork operation in the correct chronological order from start to finish.
- 1Carrying out a preliminary reconnaissance survey to inspect the terrain and select suitable main survey stations.
- 2Driving station pegs into the ground and positioning ranging poles to establish straight baselines.
- 3Measuring distances along the survey lines using a measuring chain and taking perpendicular offsets to details.
- 4Entering all linear measurements, offsets, and field sketches systematically into the survey field book.
- 5Plotting the recorded measurements to a specified scale in the drawing office to produce the final survey plan.
Cevap
The correct operational order for carrying out a chain survey is: first, carrying out a preliminary reconnaissance survey; second, driving station pegs and positioning ranging poles; third, measuring distances along survey lines and taking perpendicular offsets; fourth, entering measurements and sketches into the field book; and fifth, plotting the recorded measurements to scale in the office.
Chain surveying follows a strict procedural sequence: reconnaissance survey occurs first to inspect terrain and select stations; ranging poles and pegs are then set up to establish straight baselines; chaining along lines and offset measurements follow; measurements are recorded directly in the field book during the process; and finally, office plotting synthesizes the field notes into a scaled map.
