What information must always appear on the first page of a field survey book?
Answer: Project name, surveyor's name, date, and job number
A properly started field book must include the project name, surveyor/technician name, date, job number, and instrument used so records can be identified and authenticated.
What is the correct procedure for correcting an error in handwritten field notes?
Answer: Draw a single line through the error and write the correction nearby
Field note errors must be corrected by drawing a single line through the incorrect value, leaving it legible, and writing the corrected value beside it.
What is the purpose of recording a 'closure' in traverse field notes?
Answer: To document that the traverse returns to its starting point within allowable error
A traverse closure verifies that the sum of latitudes and departures equals zero (or within tolerance), confirming the survey's mathematical accuracy.
In survey field notes, what symbol or abbreviation typically denotes a benchmark?
Answer: BM
BM is the standard abbreviation for benchmark, which is a point of known elevation used as a reference for leveling surveys.
What does 'HI' stand for in leveling field notes?
Answer: Height of Instrument
HI (Height of Instrument) is the elevation of the line of sight through the level, calculated as the benchmark elevation plus the backsight rod reading.
What is a 'foresight' reading in differential leveling?
Answer: A rod reading taken on a point whose elevation is to be determined
A foresight (FS) is a rod reading taken on a turning point or final point to determine its elevation using the formula: Elevation = HI − FS.
