Section corners are the controlling monuments established by the USPLSS that define the one-mile-square sections of the survey grid.
Question 4: A surveyor measures a slope distance of 250.00 ft at a vertical angle of +3°30'. What is the approximate horizontal distance?
- 248.66 ft
- 250.00 ft
- 247.11 ft
- 249.31 ft (Correct answer)
Correct answer: 249.31 ft
Horizontal distance = slope distance × cos(vertical angle) = 250.00 × cos(3°30') ≈ 249.31 ft.
Question 5: What is an easement?
- Full ownership of a portion
- Property tax type
- Right to use another persons land for specific purpose without owning it (Correct answer)
- Temporary permit
Correct answer: Right to use another persons land for specific purpose without owning it
This legal right allows use without ownership.
Question 6: Which legal doctrine holds that when a deed conveys land bounded by a highway or road, the grantee receives title to the centerline of that road, absent contrary intent?
- Riparian doctrine
- Easement by necessity
- Highway centerline presumption (Correct answer)
- Eminent domain
Correct answer: Highway centerline presumption
The highway centerline presumption (or centerline rule) holds that a conveyance abutting a road typically extends to the road's centerline unless the deed clearly states otherwise.
Question 7: What is an inverse calculation in surveying?
- Computing bearing and distance between two known coordinate points (Correct answer)
- Reversing a survey
- Calculating the opposite of a result
- Undoing a measurement
Correct answer: Computing bearing and distance between two known coordinate points
Known coordinates yield the direction and distance between them.
Question 8: What is the coordinate method for area?
- Using boundary point coordinates with cross-multiplication formula (Correct answer)
- Walking the perimeter
- Aerial photo estimation
- Grid square counting
Correct answer: Using boundary point coordinates with cross-multiplication formula
Mathematical formulas provide precise area from coordinates.
Question 9: When referencing a property corner, what information should a witness corner contain?
- Bearing, distance, and description of the true corner location (Correct answer)
- The deed book and page number
- Only the PLSS township and range
- Only the bearing and distance to the true corner
Correct answer: Bearing, distance, and description of the true corner location
A witness corner (reference monument) must record bearing, distance, and a complete description so the true corner can be relocated.
Question 10: What is the effect of atmospheric refraction on a line of sight in leveling?
- It bends the line of sight upward, causing the computed elevation to be too high (Correct answer)
- It bends the line of sight downward toward Earth, causing rod readings to appear too low
- It has no measurable effect at distances under 1,000 ft
- It bends the line of sight upward away from Earth, causing rod readings to appear too high
Correct answer: It bends the line of sight upward, causing the computed elevation to be too high
Atmospheric refraction curves the line of sight upward, making distant objects appear higher than they are, so rod readings appear smaller and computed elevations appear too high.
Question 11: The tangent length (T) of a simple circular curve with radius R = 600 ft and central angle Δ = 38°20' is closest to:
- 214.5 ft
- 196.4 ft
- 208.8 ft (Correct answer)
- 202.3 ft
Correct answer: 208.8 ft
T = R × tan(Δ/2) = 600 × tan(19°10') = 600 × 0.34730 ≈ 208.8 ft.
Question 12: Which RTK GNSS technique uses a single fixed base station and can accumulate positional error with distance from the base?
- Network RTK (NRTK)
- PPP (Precise Point Positioning)
- DGNSS (Differential GNSS)
- Conventional RTK (Correct answer)
Correct answer: Conventional RTK
Conventional RTK uses one base station and accuracy degrades with baseline length (roughly 1 ppm), while Network RTK uses multiple reference stations to mitigate this effect.
Question 13: The Federal Fair Housing Act has implications for surveyors when they are asked to:
- Calculate lot areas in minority neighborhoods differently than in majority-white neighborhoods (Correct answer)
- Use metric units instead of U.S. customary units
- Follow state licensing renewal requirements
- Determine property corner depth below frost line
Correct answer: Calculate lot areas in minority neighborhoods differently than in majority-white neighborhoods
Applying different survey standards or refusing service based on neighborhood demographics would constitute discrimination prohibited by the Fair Housing Act.
Question 14: What does a 'match line' on a large-scale plan set indicate?
- The line along which cut and fill volumes are equal
- The boundary between two different zoning districts
- Where two different property surveys overlap
- Where the drawing continues on another sheet (Correct answer)
Correct answer: Where the drawing continues on another sheet
A match line shows where a large plan is split across multiple sheets, with the drawing continuing at the same location on the referenced sheet.
Question 15: What ethical consideration is most critical when handling client information as a land surveyor?
- Using the information to market surveying services
- Sharing the information with other surveyors without consent
- Maintaining client confidentiality and using the information solely for its intended purpose (Correct answer)
- Providing the information to government agencies for public use
Correct answer: Maintaining client confidentiality and using the information solely for its intended purpose
Client confidentiality is a cornerstone of ethical professional practice for land surveyors, just as it is in many other professions. Surveyors often handle sensitive information about property ownership, financial details, and personal plans. Ethically, they are obligated to protect this information, ensuring it is not disclosed without consent and is used strictly for the purpose of the surveying services agreed upon, thereby building trust and upholding professional integrity.
Question 16: What is a curve calculation in route surveying?
- Calculating curvature of the earth
- Determining elements of horizontal and vertical curves for road and railway design (Correct answer)
- Measuring curved walls
- Bending survey instruments
Correct answer: Determining elements of horizontal and vertical curves for road and railway design
Road and rail design requires precise curve geometry.
Question 17: A surveyor accepts a project but later realizes the scope exceeds his current competence in a specialized area. What is the ethically correct course of action?
- Request that the client lower the project standards
- Subcontract the entire project without the client's knowledge
- Complete the work anyway to avoid disappointing the client
- Withdraw from the project or associate with a competent specialist (Correct answer)
Correct answer: Withdraw from the project or associate with a competent specialist
Ethical codes require surveyors to practice only within their areas of competence, and to disclose limitations or bring in qualified assistance when needed.
Question 18: In the Universal Transverse Mercator (UTM) system, each zone spans how many degrees of longitude?
- 9°
- 12°
- 6° (Correct answer)
- 3°
Correct answer: 6°
The UTM system divides the world into 60 zones, each spanning 6° of longitude, for a total coverage of 360°.
Question 19: In a geodetic survey, the 'deflection of the vertical' refers to:
- The difference in elevation between benchmarks
- The angle between true north and grid north
- The angular difference between the normal to the ellipsoid and the direction of gravity (Correct answer)
- The error in astronomic azimuth due to gyroscope drift
Correct answer: The angular difference between the normal to the ellipsoid and the direction of gravity
Deflection of the vertical is the angle between the ellipsoidal normal and the local plumb line (direction of gravity), affecting astronomic vs. geodetic positions.
Question 20: In differential leveling, a backsight of 8.213 ft is taken on a benchmark (elev = 504.127 ft) and a foresight of 2.645 ft is taken on the next point. What is the elevation of the next point?
- 513.940 ft
- 509.695 ft (Correct answer)
- 495.559 ft
- 506.772 ft
Correct answer: 509.695 ft
HI = 504.127 + 8.213 = 512.340 ft; Elev = 512.340 − 2.645 = 509.695 ft.
Question 21: What trigonometric function relates opposite side to hypotenuse?
- Cosine
- Tangent
- Sine (Correct answer)
- Cotangent
Correct answer: Sine
Sine = opposite / hypotenuse in a right triangle.
Question 22: The term 'simultaneous conveyance' is important in boundary law because it means:
- All deeds in a subdivision are recorded at exactly the same moment
- Lots created from the same plat or subdivision have equal (co-equal) rights with no senior or junior priority among themselves (Correct answer)
- Two adjoining owners exchange parcels in a single transaction
- A grantor conveys land to multiple grantees sharing ownership
Correct answer: Lots created from the same plat or subdivision have equal (co-equal) rights with no senior or junior priority among themselves
Simultaneous conveyance means that lots platted together have co-equal rights, so the senior/junior deed priority rule does not apply among them.
Question 23: When performing a GPS survey to establish vertical control, the orthometric height (H) is derived by:
- H = N − h
- H = h − N (Correct answer)
- H = h × N
- H = h + N
Correct answer: H = h − N
Orthometric height H equals ellipsoidal height h minus the geoid undulation N (H = h − N).
Question 24: In stadia surveying, if the stadia interval factor (K) is 100 and the rod intercept (s) is 1.25 ft, what is the horizontal distance (assuming a horizontal sight)?
- 125.00 ft (Correct answer)
- 1250.00 ft
- 100.25 ft
- 12.50 ft
Correct answer: 125.00 ft
Stadia horizontal distance (level sight) = K × s = 100 × 1.25 = 125.00 ft (plus instrument constant C, usually negligible for modern instruments).
Question 25: Which legal doctrine provides that a deed recorded first in time generally prevails over a later deed from the same grantor in states without notice or race-notice statutes?
- Race doctrine (pure race recording) (Correct answer)
- Constructive notice doctrine
- Race-notice doctrine
- Notice doctrine
Correct answer: Race doctrine (pure race recording)
Under the pure race doctrine, the first party to record the deed wins regardless of their knowledge of prior conveyances, making recording speed determinative.
Question 26: What is the purpose of 'double centering' (double-direct) when turning angles with a total station?
- To allow the instrument to be used in both direct and reversed positions simultaneously
- To double the measured angle for greater precision
- To check that the prism target is centered on the point
- To eliminate or detect errors caused by non-perpendicularity of the horizontal and vertical axes (Correct answer)
Correct answer: To eliminate or detect errors caused by non-perpendicularity of the horizontal and vertical axes
Double centering turns the angle in both direct and reversed telescope positions; averaging the two readings eliminates systematic errors due to instrument axis misalignment.
Question 27: What is the primary difference between a 'monument' and a 'marker' in boundary surveying?
- There is no legal distinction between the two terms
- A monument is a physical object occupying the true position of a corner; a marker is placed near but not at the corner (Correct answer)
- A monument is set by a surveyor; a marker is set by a government agency
- A monument is a natural object; a marker is artificial
Correct answer: A monument is a physical object occupying the true position of a corner; a marker is placed near but not at the corner
A monument occupies the exact corner position and controls the boundary, while a marker (or witness post) is placed nearby to help find the monument.
Question 28: A level rod reading of 8.72 ft is taken on a benchmark with a known elevation of 452.30 ft. The height of instrument (HI) is:
- 443.58 ft
- 452.30 ft
- 460.00 ft
- 461.02 ft (Correct answer)
Correct answer: 461.02 ft
HI = Benchmark elevation + backsight reading = 452.30 + 8.72 = 461.02 ft.
Question 29: A surveyor uses a steel tape that is 100.02 ft long instead of exactly 100.00 ft. After measuring a 500 ft line, the corrected distance is:
- 500.02 ft
- 500.10 ft (Correct answer)
- 499.90 ft
- 499.98 ft
Correct answer: 500.10 ft
Correction per tape length = +0.02 ft; for 5 tape lengths: 5 × 0.02 = +0.10 ft; corrected distance = 500.00 + 0.10 = 500.10 ft.
Question 30: In differential leveling, a 'backsight' reading is taken to:
- Determine the elevation of the next point forward
- Check the rod reading against a turning point
- Close the level loop back to the starting BM
- Establish the height of instrument (HI) from a known elevation (Correct answer)
Correct answer: Establish the height of instrument (HI) from a known elevation
A backsight is read on a point of known elevation to compute the height of instrument (HI = known elevation + BS reading).
Question 31: Which geoid model is the official vertical datum reference for the conterminous United States?
- NAVD 88
- GEOID18
- GEOID12B (Correct answer)
- EGM2008

GEOID12B is the NGS model used to convert between ellipsoidal heights (GPS) and orthometric heights relative to NAVD 88.
Question 32: A leveling rod reading of 4.832 ft is taken at a point 500 ft from the instrument. What combined curvature and refraction correction should be applied?
- Approximately 0.50 ft
- Approximately 0.001 ft
- Approximately 1.00 ft
- Approximately 0.010 ft (negligible for most surveys) (Correct answer)
Correct answer: Approximately 0.010 ft (negligible for most surveys)
Combined curvature and refraction ≈ 0.0206 × d² (miles); at 500 ft (~0.095 mi), correction ≈ 0.0002 ft, which is negligible.
Question 33: A vertical curve connects a +2.50% grade and a −1.50% grade. The algebraic difference in grades (A) is:
- 4.00% (Correct answer)
- 2.50%
- 1.00%
- −4.00%
Correct answer: 4.00%
A = g₂ − g₁ = −1.50% − (+2.50%) = −4.00%; the absolute value |A| = 4.00%.
Question 34: A 'cul-de-sac' shown on a subdivision plat is characterized by which geometric feature?
- A four-way intersection with a traffic circle
- A curved street with no cross streets
- A T-intersection with a turning lane

Correct answer: A dead-end street with a circular turnaround
A cul-de-sac is a dead-end street terminating in a circular bulb to allow vehicles to turn around.
Question 35: On a construction plan set, which sheet typically shows grading, drainage, and earthwork information?
- Civil grading plan (Correct answer)
- Structural framing plan
- Electrical single-line diagram
- Architectural floor plan
Correct answer: Civil grading plan
Civil grading plans depict proposed and existing elevations, cut/fill areas, drainage patterns, and related earthwork.
Question 36: In a geodetic survey, the geoid is best described as:
- The equipotential surface of Earth's gravity field approximating mean sea level (Correct answer)
- A mathematical ellipsoid fitted to Earth's surface
- The topographic surface of the land
- A sphere with Earth's mean radius
Correct answer: The equipotential surface of Earth's gravity field approximating mean sea level
The geoid is the equipotential gravity surface that approximates mean sea level and serves as the vertical datum reference.
Question 37: Which map projection preserves true directions from a central point, making it useful for navigation charts?
- Gnomonic (Correct answer)
- Albers Equal-Area Conic
- Mercator
- Lambert Conformal Conic
Correct answer: Gnomonic
The Gnomonic projection is the only projection on which all great circles appear as straight lines, making directions from the center true.
Question 38: The parallax difference method in stereophotogrammetry is used to determine:
- Camera tilt during aerial acquisition
- Ground control point coordinates
- Horizontal distances from a single photograph
- Elevation differences between points using the change in x-parallax (Correct answer)
Correct answer: Elevation differences between points using the change in x-parallax
Height differences are calculated from the difference in x-parallax between the target point and a reference point using the parallax bar formula.
Question 39: A 'double proportionate measurement' in PLSS is used to restore which type of corner?
- Interior quarter-section corner (Correct answer)
- Section corner common to four townships
- Quarter-section corner on a township line
- Standard corner on a base line
Correct answer: Interior quarter-section corner
Double proportionate measurement applies to lost interior quarter-section corners, distributing error both east-west and north-south from the controlling corners.
Question 40: Under which scenario is a surveyor most likely to face a claim of professional negligence?
- Charging a fee higher than a competitor's rate
- Completing a survey faster than the industry average
- Failing to locate an existing easement that was visible in public records (Correct answer)
- Using GPS equipment instead of traditional total station instruments
Correct answer: Failing to locate an existing easement that was visible in public records
Failing to research and report on encumbrances such as easements that are discoverable in public records falls below the standard of care and can constitute professional negligence.
Question 41: The standard deviation of a single measurement where n repeated observations have a standard deviation of the mean (σm) is:
- σ = σm × √n (Correct answer)
- σ = σm × n
- σ = σm / √n
- σ = σm²
Correct answer: σ = σm × √n
The standard deviation of a single observation σ = σm × √n, because the mean is more precise than any individual measurement by a factor of √n.
Question 42: In a legal description using the Public Land Survey System (PLSS), a 'section' nominally contains how many acres?
- 160 acres
- 320 acres
- 640 acres (Correct answer)
- 40 acres
Correct answer: 640 acres
A standard PLSS section is nominally 1 mile × 1 mile = 640 acres, though boundary sections may vary due to convergence of meridians and survey errors.
Question 43: Using the coordinate method, a triangle has vertices at (0,0), (6,0), and (3,4). What is its area in square units?
- 10
- 14
- 12 (Correct answer)
- 8
Correct answer: 12
Area = ½|x₁(y₂−y₃)+x₂(y₃−y₁)+x₃(y₁−y₂)| = ½|0(0−4)+6(4−0)+3(0−0)| = ½×24 = 12.
Question 44: What is the hierarchy of boundary evidence?
- Area strongest
- Natural monuments, artificial monuments, distances, directions, area (Correct answer)
- All equal weight
- Distances always control
Correct answer: Natural monuments, artificial monuments, distances, directions, area
There is a specific ranking of evidence strength.
Question 45: Under the Public Land Survey System (PLSS), who holds legal authority to establish section corners that are lost and cannot be restored by evidence?
- The Bureau of Land Management (BLM) under federal law (Correct answer)
- The county assessor's office
- The original homesteader's successors
- Any licensed surveyor working in that county
Correct answer: The Bureau of Land Management (BLM) under federal law
Under 43 U.S.C. § 772, only the BLM (or its predecessor GLO) has legal authority to officially re-establish lost PLSS corners through dependent resurveys.
Question 46: The Compass (Bowditch) Rule for traverse adjustment distributes the misclosure:
- Proportional to the angle at each traverse station
- Only to the legs with the largest measured angles
- Proportional to the length of each traverse leg (Correct answer)
- Equally among all traverse legs
Correct answer: Proportional to the length of each traverse leg
The Compass Rule apportions latitude and departure corrections to each leg in proportion to that leg's length relative to the total traverse length.
Question 47: Orthometric height is defined as the:
- Height above the geoid, measured along the plumb line direction (Correct answer)
- Height determined by trigonometric leveling above a local benchmark
- Height above the Clarke 1866 ellipsoid used in NAD27
- GPS-derived height above the WGS84 ellipsoid
Correct answer: Height above the geoid, measured along the plumb line direction
Orthometric height (H) is the distance from the geoid to the point, measured along the curved plumb line, and represents the standard definition of elevation.
Question 48: What is the method of least squares?
- Measuring smallest areas
- Reducing measurements needed
- Minimizing sum of squared residuals to find best-fit survey values (Correct answer)
- Finding shortest distance
Correct answer: Minimizing sum of squared residuals to find best-fit survey values
This optimally distributes errors across all measurements.
Question 49: The combined scale factor for converting ground distances to grid distances is computed as:
- Meridian convergence multiplied by the projection distortion factor
- The grid scale factor divided by the elevation factor
- Orthometric height divided by ellipsoidal height
- The elevation factor multiplied by the grid (projection) scale factor (Correct answer)
Correct answer: The elevation factor multiplied by the grid (projection) scale factor
CSF = (elevation factor) × (grid scale factor), where the elevation factor accounts for height above the ellipsoid and the grid scale factor comes from the map projection.
Question 50: A surveyor discovers that the recorded deed calls conflict with the physical occupation lines on the ground. Which evidence generally takes the highest priority in resolving the conflict?
- Occupation lines and senior rights of adjoining owners
- Recorded plat distances
- Original survey monuments on the ground (Correct answer)
- Written deed calls (metes and bounds)
Correct answer: Original survey monuments on the ground
Original monuments set by the original survey take highest priority because they represent the intent of the original surveyor; calls, distances, and area follow in descending order.
Question 51: A surveyor uses a total station to measure an azimuth of 214°33' to a target. What is the equivalent bearing?
- S 55°27' W
- N 34°33' W
- S 34°33' E
- S 34°33' W (Correct answer)
Correct answer: S 34°33' W
Azimuths between 180° and 270° are in the SW quadrant; bearing = azimuth − 180° = 214°33' − 180° = S 34°33' W.
Question 52: In the method of least squares adjustment, the condition minimized is:
- The sum of the absolute values of the residuals
- The largest single residual
- The sum of the residuals
- The sum of the squares of the residuals (v'Pv) (Correct answer)
Correct answer: The sum of the squares of the residuals (v'Pv)
Least squares minimizes Σ(p·v²), the weighted sum of squared residuals, to produce the most probable solution.
Question 53: When using a total station, 'face left' and 'face right' observations are averaged primarily to eliminate:
- Scale factor errors in the EDM
- Atmospheric refraction effects
- Instrument leveling errors
- Collimation error and vertical axis tilt (Correct answer)
Correct answer: Collimation error and vertical axis tilt
Observing in both face-left and face-right positions and averaging the results cancels out systematic errors such as collimation error and horizontal axis tilt.
Question 54: A traverse has a departure closure error of +0.42 ft and a latitude closure error of -0.56 ft. What is the linear closure error?
- 0.98 ft
- 0.49 ft
- 0.70 ft (Correct answer)
- 0.14 ft
Correct answer: 0.70 ft
Linear closure = √(0.42² + 0.56²) = √(0.1764 + 0.3136) = √0.49 = 0.70 ft.
Question 55: A slope distance of 542.30 ft is measured on a grade of 3.75%. What is the horizontal distance?
- 540.12 ft
- 538.47 ft
- 541.91 ft (Correct answer)
- 542.68 ft
Correct answer: 541.91 ft
Horizontal distance = slope distance × cos(arctan(0.0375)) ≈ 542.30 × 0.99930 ≈ 541.91 ft.
Question 56: Which type of property description is considered the weakest and most prone to causing boundary disputes?
- Government rectangular survey description
- Strip or acreage description with no monuments or bearings (Correct answer)
- Metes and bounds description
- Lot and block (recorded plat) description
Correct answer: Strip or acreage description with no monuments or bearings
Descriptions that lack monuments, bearings, or distances and rely solely on acreage or informal strip references are legally weak and highly prone to boundary disputes.
Question 57: The interior angles of a closed five-sided traverse sum to 540°. If four measured angles are 98°14', 112°33', 87°47', and 125°06', what is the fifth angle (assuming no angular error)?
- 116°40'
- 117°20'
- 115°20'
- 116°20' (Correct answer)
Correct answer: 116°20'
Sum of four angles = 423°40'; fifth angle = 540°00' − 423°40' = 116°20'.
Question 58: On a survey map legend, a symbol showing a filled circle at a corner followed by a pipe description typically represents what?
- A utility manhole
- A traffic signal pole
- A found or set iron pipe or monument (Correct answer)
- A water well location
Correct answer: A found or set iron pipe or monument
Filled circles or squares with pipe/rod descriptions in a legend denote survey monuments, either found during fieldwork or set by the surveyor.
Question 59: What is a metes and bounds description?
- Building height method
- Soil classification
- Tracing boundaries using directions, distances, and landmarks from a point of beginning (Correct answer)
- Coordinate system
Correct answer: Tracing boundaries using directions, distances, and landmarks from a point of beginning

- Clarke 1866
- Bessel 1841
- WGS 84
- GRS 80 (Correct answer)
Correct answer: GRS 80
NAD 83 is based on the Geodetic Reference System 1980 (GRS 80) ellipsoid, though it is nearly identical to the WGS 84 ellipsoid used by GPS.
Question 61: A digital elevation model (DEM) is most commonly used in GIS-based surveying to:
- Store attribute data about land ownership parcels
- Record GPS satellite orbital parameters
- Display aerial photograph mosaics
- Represent the bare-earth terrain surface for topographic analysis (Correct answer)
Correct answer: Represent the bare-earth terrain surface for topographic analysis
A DEM represents the bare-earth surface as a raster grid of elevation values, enabling slope, aspect, watershed, and visibility analyses.
Question 62: Which of the following constitutes an 'encumbrance' on real property that a surveyor may be expected to locate and show on a survey plat?
- The owner's homeowner's insurance policy
- The property owner's mortgage balance
- State income tax obligations of the owner
- A utility easement crossing the parcel (Correct answer)
Correct answer: A utility easement crossing the parcel
Utility easements are encumbrances — rights held by others that burden the property — and surveyors are typically required to locate and depict them on survey plats.
Question 63: What is a coordinate transformation?
- Converting positions between different coordinate systems (Correct answer)
- Updating software
- Moving physical markers
- Changing map colors
Correct answer: Converting positions between different coordinate systems
Positions must sometimes be expressed in different reference systems.
Question 64: Which feature of an automatic level compensates for small residual tilts of the instrument?
- Striding level
- Foot screws
- Plate bubble
- Pendulum-suspended optical compensator (Correct answer)
Correct answer: Pendulum-suspended optical compensator
The automatic level uses a gravity-controlled pendulum compensator to keep the line of sight horizontal within its operating range.
Question 65: What is a plat map?
- Topographic map
- Contour map
- Soil map
- Scaled diagram of land divided into lots, blocks, streets (Correct answer)
Correct answer: Scaled diagram of land divided into lots, blocks, streets
This map shows subdivision of land into parcels.
Question 66: Which map projection is used by the US State Plane Coordinate System for states with a predominantly east-west extent?
- Lambert Conformal Conic (Correct answer)
- Azimuthal Equidistant
- Albers Equal-Area Conic
- Transverse Mercator
Correct answer: Lambert Conformal Conic
Lambert Conformal Conic is used for east-west oriented states/zones because it minimizes distortion along parallels.
Question 67: In differential leveling, what is the formula for the elevation of a new point?
- Elevation = Backsight + Foresight
- Elevation = Backsight − HI
- Elevation = HI + Foresight
- Elevation = HI − Foresight (Correct answer)
Correct answer: Elevation = HI − Foresight
The new elevation equals the Height of Instrument (HI) minus the foresight rod reading: Elev = HI − FS.
Question 68: The term 'latitudes and departures' in traverse calculations refers to:
- Bearing and distance of each leg
- Geographic coordinates of latitude and longitude
- North-south and east-west components of a traverse course (Correct answer)
- Horizontal and vertical distance components
Correct answer: North-south and east-west components of a traverse course
Latitude is the north-south component and departure is the east-west component of each traverse course, used to compute coordinate changes.
Question 69: What is error of closure?
- Discrepancy between calculated end position and known start of closed traverse (Correct answer)
- Completion time
- Survey cost
- Final measurement
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 70: What is an azimuth?
- Ground slope
- Horizontal angle measured clockwise from north, 0-360 degrees (Correct answer)
- Foundation depth

Correct answer: Horizontal angle measured clockwise from north, 0-360 degrees
This goes completely around the compass from north.
Question 71: A surveyor distributes a closure error of 0.96 ft over a 4-course traverse using the compass (Bowditch) rule. Course 1 has a length of 400 ft and the total traverse length is 1,600 ft. What correction is applied to Course 1's latitude?
- 0.48 ft
- 0.24 ft (Correct answer)
- 0.06 ft
- 0.12 ft
Correct answer: 0.24 ft
Correction = (course length / total length) × total error = (400/1600) × 0.96 = 0.25 × 0.96 = 0.24 ft.
Question 72: What does 'index error' refer to in theodolite/total station usage?
- The angular error caused by instrument tilt
- The difference between face-left and face-right horizontal readings
- The error introduced by an off-center optical plummet
- The deviation of the vertical circle index from 0° when the bubble is centered (Correct answer)
Correct answer: The deviation of the vertical circle index from 0° when the bubble is centered
Index error is the amount by which the vertical circle reads something other than 0° (or 90°) when the instrument is leveled.
Question 73: A surveyor needs to convert 45°27'36" to decimal degrees. What is the result?
- 45.463°
- 45.460° (Correct answer)
- 45.476°
- 45.456°
Correct answer: 45.460°
27'/60 = 0.450°; 36"/3600 = 0.010°; total = 45 + 0.450 + 0.010 = 45.460°.
Question 74: In PLSS, 'lot' parcels are typically found in which sections of a township?
- Sections in the interior of the township
- Sections along the north and west boundaries (Correct answer)
- Only in Section 16

Correct answer: Sections along the north and west boundaries
Fractional lots resulting from subdivision adjustments are typically found along the north and west boundaries of a township where closure errors accumulate.
Question 75: A surveyor is asked to certify that a building complies with a setback requirement, but field measurements show a slight encroachment. The client asks the surveyor to 'round' the measurement to show compliance. The surveyor should:
- Round the measurement if the error is within typical survey tolerance
- Report the encroachment only on an internal memo and certify compliance publicly
- Seek a second opinion from another surveyor before reporting
- Refuse to falsify findings and accurately report the encroachment (Correct answer)
Correct answer: Refuse to falsify findings and accurately report the encroachment
Falsifying or manipulating survey data to achieve a desired result violates professional ethics codes and potentially constitutes fraud.
Question 76: A transit-stadia measurement gives a rod intercept of 1.240 ft with a stadia constant K = 100 and C = 1.0. What is the horizontal distance (for a horizontal sight)?
- 126.0 ft
- 124.0 ft
- 125.0 ft (Correct answer)
- 123.4 ft
Correct answer: 125.0 ft
Horizontal distance = K × s + C = 100 × 1.240 + 1.0 = 124.0 + 1.0 = 125.0 ft.
Question 77: What is the key distinction between 'geographic north' and 'magnetic north' that a surveyor must account for?
- They are the same direction at all points on Earth
- Geographic north points to the north magnetic pole; magnetic north points to true north
- Geographic north is the direction of the Earth's rotational axis; magnetic north varies with location and time due to the Earth's magnetic field (Correct answer)
- Geographic north is used only in GPS surveys; magnetic north in all other surveys
Correct answer: Geographic north is the direction of the Earth's rotational axis; magnetic north varies with location and time due to the Earth's magnetic field
Geographic (true) north aligns with Earth's rotational axis, while magnetic north varies spatially and temporally; the difference is called magnetic declination.
Question 78: What is coordinate geometry (COGO)?
- A computer brand
- Mathematical computation of coordinates, areas, distances, and directions from survey data (Correct answer)

A deed of trust is a security instrument in which a borrower conveys title to a trustee to hold as collateral for a lender until the loan is repaid.
Question 84: A closed traverse has 5 sides. The sum of interior angles should equal:
- 540° (Correct answer)
- 360°
- 900°
- 720°
Correct answer: 540°
Sum of interior angles = (n - 2) × 180° = (5 - 2) × 180° = 540°.
Question 85: In a closed traverse, the angular closure error is distributed by the Compass Rule. What does this rule assume?
- Errors are proportional to the latitude and departure of each course
- The traverse starts and ends at the same point
- Errors are proportional to the length of each course (Correct answer)
- All angles are equally reliable
Correct answer: Errors are proportional to the length of each course
The Compass Rule (Bowditch Rule) distributes closure error in proportion to each course's length relative to the total traverse length.

Question 92: What is the significance of "northing" and "easting" in coordinate systems?
- They indicate the elevation and slope of a surveyed point
- They represent the latitude and longitude of a specific location
- They are used to describe the distances north and east of a specific origin point in a coordinate system (Correct answer)
- They describe the angle of a surveyed line relative to true north
Correct answer: They are used to describe the distances north and east of a specific origin point in a coordinate system
Northing and Easting are planar coordinates used in grid systems, such as UTM or State Plane Coordinate Systems. Northing measures the distance north from a specific origin point, while Easting measures the distance east from a central meridian or false origin. Together, these values provide a unique and precise two-dimensional location for any point within that particular coordinate system.
Question 93: Which of the following best describes "adverse possession"?
- A procedure for modifying property boundaries through mutual agreement
- A method to resolve property disputes through arbitration
- A legal right to access land owned by another for specific purposes
- A legal principle allowing a person to claim ownership of land by continuous, open, and hostile possession over a certain period (Correct answer)
Correct answer: A legal principle allowing a person to claim ownership of land by continuous, open, and hostile possession over a certain period
Adverse possession is a legal doctrine that allows an individual to acquire title to another's land by occupying it openly, notoriously, continuously, exclusively, and hostilely for a statutory period, without the owner's permission. This principle is significant in land surveying as it can lead to changes in property boundaries and ownership, requiring surveyors to be aware of its implications when researching and delineating property lines.
Question 94: Difference between accuracy and precision?
- Accuracy: closeness to true value; Precision: consistency of measurements (Correct answer)
- Identical concepts
- Accuracy is speed
- Precision always more important

Question 96: What does a dashed line typically represent on a survey plat?
- A contour line
- A section line
- A recorded easement or right-of-way (Correct answer)
- A property line with a known bearing
Correct answer: A recorded easement or right-of-way
Dashed lines on survey plats commonly denote easements, rights-of-way, or other encumbrances that affect but do not define ownership boundaries.
Question 97: What is EDM?
- Technology using electromagnetic waves to measure distances accurately (Correct answer)
- Angle-only method
- Software program
- GPS receiver type
Correct answer: Technology using electromagnetic waves to measure distances accurately
Electromagnetic waves determine distance between points.
Question 98: Which instrument is most appropriate for transferring elevations across a wide river where direct leveling is impractical?
- Total station using trigonometric leveling with reciprocal observations (Correct answer)
- Automatic level with a long rod
- Hand level and measuring tape
- Laser level with a rotating beam
Correct answer: Total station using trigonometric leveling with reciprocal observations
Reciprocal trigonometric leveling with a total station cancels refraction and curvature errors when observations are exchanged from both banks.
Question 99: Which curve element represents the distance along the arc from the PC to the PT?
- Length of Curve (L) (Correct answer)
- Long Chord (LC)
- Middle Ordinate (M)
- External Distance (E)

Correct answer: A triangular or irregular strip of land left unintentionally between two surveys
A gore is a thin, often triangular strip of land inadvertently omitted between two surveys or conveyances.
Question 101: A vertical curve connects a +3.5% grade with a -2.5% grade. The algebraic difference of grades (A) equals:
- 6.0% (Correct answer)
- -6.0%
- 1.0%
- -1.0%
Correct answer: 6.0%
A = g1 - g2 = +3.5% - (-2.5%) = +6.0%, indicating a crest (sag) vertical curve.
Question 102: A map scale of 1:24,000 means that one inch on the map equals how many feet on the ground?
- 2,000 feet (Correct answer)
- 24,000 feet
- 240 feet
- 2,400 feet
Correct answer: 2,000 feet
At 1:24,000, one inch equals 24,000 inches on the ground, which converts to 2,000 feet (24,000 ÷ 12 = 2,000).
Question 103: Two points A and B have elevations of 1,245.82 ft and 1,189.37 ft respectively, and a horizontal distance of 830.0 ft. What is the percent grade from A to B?
- −5.60%
- +6.80%
- +5.60%
- −6.80% (Correct answer)
Correct answer: −6.80%
Grade = (elev B − elev A) / horizontal distance × 100 = (1189.37 − 1245.82) / 830.0 × 100 = −6.80%.
Question 104: When reading a cadastral map, what does the term "parcel" refer to?
- A small section of a larger property that is intended for agricultural use
- A unit of land that has been surveyed and mapped, often for legal or ownership purposes (Correct answer)
- A geographic feature such as a river or mountain
- A historical boundary line that is no longer in use
Correct answer: A unit of land that has been surveyed and mapped, often for legal or ownership purposes
On a cadastral map, which focuses on property boundaries and ownership, a 'parcel' refers to a distinct unit of land. This unit is typically defined by its legal description, ownership, and boundaries as determined by a survey. Cadastral maps and parcels are fundamental for property management, taxation, and legal transactions related to land.
Question 105: Which legal concept allows a property owner to claim ownership of land that has gradually and imperceptibly been added to their parcel by natural water deposit?
- Accretion (Correct answer)
- Avulsion
- Erosion
- Reliction
Correct answer: Accretion
Accretion is the gradual and imperceptible accumulation of land through natural processes (typically water-borne sediment deposit), and the new land belongs to the riparian owner.
Question 106: A 'Point of Curvature' (PC) on a highway plan marks which location?
- The center of a horizontal curve
- Where two curves of equal radius meet
- Where a tangent transitions into a horizontal curve (Correct answer)
- The highest point on a vertical curve
Correct answer: Where a tangent transitions into a horizontal curve

- Obtaining a license for commercial use of the map
- Including a detailed historical account of the property’s previous owners
- Ensuring the map meets state-specific legal and technical standards (Correct answer)
- Submitting the map to a local real estate office for approval
Correct answer: Ensuring the map meets state-specific legal and technical standards
When preparing official property boundary maps, land surveyors are legally required to adhere to stringent state-specific legal and technical standards. These standards dictate everything from the accuracy of measurements and the types of monuments used, to the format, content, and scale of the map, as well as the required certifications and seals. Compliance ensures the map is legally defensible, accurate, and suitable for recording with local authorities.
Question 108: A surveyor measures a slope distance of 250.00 ft at a vertical angle of +5°. What is the approximate horizontal distance?
- 248.98 ft (Correct answer)
- 245.11 ft
- 249.05 ft
- 250.95 ft
Correct answer: 248.98 ft
Horizontal distance = slope distance × cos(vertical angle) = 250.00 × cos(5°) ≈ 250.00 × 0.99619 ≈ 248.98 ft.
Question 109: Under common law, a landowner who conveys a parcel by a deed with a specific description generally cannot later convey overlapping land to another party because of the principle known as:
- Estoppel by deed (Correct answer)
- Riparian rights
- Adverse possession
- Dominant tenement
Correct answer: Estoppel by deed
Estoppel by deed prevents a grantor from claiming rights in property they have already conveyed to another.
