What is essential when selecting surveying equipment?
Select equipment appropriate to the task
What is the purpose of pacing in distance measurement during surveying?
Count the number of paces for approximate results
What does a small standard error indicate about a set of observations in surveying?
Closely grouped observations with small deviations from the sample mean
What is preferred in survey work: accuracy or precision?
High degree of accuracy over precision
What influence should the ultimate drawings have on the standard accuracy achieved in fieldwork during surveying?
The accuracy should be higher than necessary for the drawings size
What is the main purpose of surveying from the whole to the part?
To localize the errors
During the reconnaissance survey phase, what is the main objective?
To take an overall inspection of the area to be surveyed
What is the purpose of fixing more points using measurements from two control parts?
To locate various other points accurately
What is the purpose of passing through the reconnaissance, field work and measurement, and office work phases in the survey process?
To ensure scientific accuracy and completeness
What is an essential principle emphasized in surveying for maintaining accuracy?
Checking measurements to ensure correctness
Why is it important to localize errors in surveying?
To reduce errors and inaccuracies
What is the significance of walking through the site during the reconnaissance survey phase?
To determine the scale to be used in the survey
Why is it important to maintain honesty in surveying?
To show professionalism and avoid distortions
Which phase of the survey process involves actual measurements in the field?
Field work and measurement
What is one key responsibility of assistants during a survey?
Listening carefully to instructions and carrying them out accurately
What is the purpose of knowing the average pace length in surveying?
To use in reconnaissance surveys and small-scale mapping
Which method involves direct measurement of distances with a tape or chain?
Taping (chaining)

Wood
Learn about the fundamental surveying principle of working from whole to part, which involves establishing a precise control survey initially followed by subsidiary detail survey. This principle ensures high accuracy in surveying by first establishing control points before surveying detailed points.
