What is the standard format for recording an angle in survey field notes?
Answer: Degrees, minutes, seconds (e.g., 45°30'00")
Survey angles are recorded in degrees, minutes, and seconds (DMS format) as this is the standard convention in US land surveying practice.
What must a survey monument tag or cap typically include to be legally sufficient?
Answer: The surveyor's license number and state abbreviation
Survey monument tags must include the licensed surveyor's registration number and state so the monument can be traced to the surveyor legally responsible for it.
What is the purpose of a 'turning point' (TP) in differential leveling?
Answer: A temporary point used to transfer elevation when the instrument must be moved
A turning point is a stable temporary point where both a foresight and backsight are taken, allowing the level instrument to be repositioned without losing elevation reference.
In a survey plat, what does a 'legend' provide?
Answer: Explanations of symbols, abbreviations, and line types used on the drawing
A plat legend defines all symbols, abbreviations, and linework conventions used in the drawing so the plat can be correctly interpreted by anyone reading it.
What is meant by 'positional accuracy' in a survey report?
Answer: How closely a surveyed position agrees with its true location
Positional accuracy describes how closely a measured or computed survey point agrees with its true ground position, typically expressed as a linear uncertainty at a given confidence level.
What information is recorded in a 'control traverse' field book entry?
Answer: Station names, instrument angles, distances, and instrument/target heights
A control traverse field book entry records all raw observations including station identifiers, measured horizontal angles, distances, and instrument/prism heights needed for office reduction.
