LSIT Surveying Fundamentals 2 — Questions and Answers
Question 1: What is an azimuth?
- Horizontal angle measured clockwise from north, 0-360 degrees (Correct answer)
- Vertical angle
- Ground slope
- Foundation depth
Correct answer: Horizontal angle measured clockwise from north, 0-360 degrees
This goes completely around the compass from north.
Question 2: What is error of closure?
- Discrepancy between calculated end position and known start of closed traverse (Correct answer)
- Final measurement
- Survey cost
- Completion time
Correct answer: Discrepancy between calculated end position and known start of closed traverse
This measures how well the survey returns to its starting point.
Question 3: What is a topographic survey?
- Determines positions and elevations of features to create contour maps (Correct answer)
- Building interior survey
- Boundary-only survey
- Underground utility survey
Correct answer: Determines positions and elevations of features to create contour maps
This survey captures the shape of the land and features.
Question 4: Geodetic vs plane surveying?
- Geodetic accounts for earth curvature; plane treats surface as flat (Correct answer)
- Same thing
- Plane is more accurate
- Geodetic only for aviation
Correct answer: Geodetic accounts for earth curvature; plane treats surface as flat
The key difference is whether earths curvature matters.
Question 5: What is a plat map?
- Scaled diagram of land divided into lots, blocks, streets (Correct answer)
- Topographic map
- Contour map
- Soil map
Correct answer: Scaled diagram of land divided into lots, blocks, streets
This map shows subdivision of land into parcels.
Question 6: What is a monument in surveying?
- Physical marker at a survey point to permanently mark location (Correct answer)
- Historical building
- Surveying instrument
- Mathematical point only
Correct answer: Physical marker at a survey point to permanently mark location
These physical objects mark important points on the ground.
