Fundamentals of Surveying Exam (FS) Professional Practice, Standards, and Ethics Syllabus

List four key items that should be documented in a project's field notes.

Date and crew members; weather/conditions and equipment used; measured data (angles, distances, descriptions of found monuments); and sketches with station references. Good notes are legible, indelible, chronological, and never erased (errors are lined out).

Why should field notes be recorded in ink and corrections lined out rather than erased?

Field notes are legal records and potential courtroom evidence. Indelible ink and lined-out (rather than erased or obliterated) corrections preserve the integrity and authenticity of the original record, showing nothing was hidden or fraudulently altered.

What is the proper procedure for managing a survey crew on a multi-day boundary project to ensure quality?

Provide a clear project brief and scope, assign roles, establish control before detail work, perform redundant measurements and field checks, maintain communication, document daily progress, and review field notes each day to catch errors before leaving the site.

What is 'chain of custody' for survey records and evidence, and why does it matter?

Chain of custody is the documented, unbroken trail showing who collected, handled, and stored records or physical evidence (e.g., monuments, samples) and when. It matters because it establishes the reliability and admissibility of the evidence in legal proceedings.

What is record retention, and what is a typical concern that drives surveyors to retain project records long-term?

Record retention is the practice of preserving project documents, field notes, and computations for a defined period. Surveyors retain records long-term (often permanently) because boundary disputes and liability claims can arise many years after a survey, and the records serve as legal evidence and professional reference.

What sources should a surveyor research before performing a boundary survey?

Recorded deeds and the chain of title, recorded plats/subdivision maps, prior surveys, county/parish recorder and assessor records, court records, easements and right-of-way maps, government land records (e.g., BLM/GLO records for PLSS), and adjoiner deeds.

What are GLO/BLM records, and why are they important in research?

General Land Office (GLO) records—now maintained by the Bureau of Land Management (BLM)—contain the original survey plats and field notes for the Public Land Survey System (PLSS). They are the controlling authority for retracing original public land boundaries and locating original corners.

What is a chain of title, and why does a surveyor research it?

A chain of title is the chronological sequence of recorded ownership transfers (deeds) for a parcel back to its origin. Surveyors research it to identify senior/junior rights, easements, and the controlling legal description that defines the boundary being retraced.

What is the difference between a senior right and a junior right in boundary law?

A senior right belongs to the parcel or deed conveyed first in time; a junior right belongs to a later conveyance. When descriptions conflict or overlap, the senior right generally prevails ('first in time, first in right'), and the junior parcel takes what remains.

Name the primary federal regulatory agency governing workplace field safety in the U.S. and the standard it sets.

OSHA (Occupational Safety and Health Administration). It establishes and enforces workplace safety standards, including those applicable to surveying field operations such as excavation, traffic, and personal protective equipment requirements.

What does the acronym PPE stand for, and give three examples relevant to a survey crew.

PPE stands for Personal Protective Equipment. Examples for a survey crew: high-visibility safety vests, hard hats, steel-toed boots, safety glasses, and gloves.

What is the standard purpose of '811 / Call Before You Dig' for survey and construction field work?

811 is the national one-call notification number used to request that underground utilities be located and marked before any digging or driving of stakes/monuments, preventing damage to buried utilities and reducing injury and liability.

What are the APWA uniform color codes for marking underground utilities? Give at least four.

Red = electric power lines/cables; Yellow = gas, oil, steam, petroleum; Orange = communication, alarm, signal, cable/conduit; Blue = potable water; Green = sewer and drain lines; Purple = reclaimed water/irrigation; Pink = temporary survey markings; White = proposed excavation.

What basic safety precautions should a survey crew take when working in or near a roadway?

Wear high-visibility apparel (ANSI/ISEA compliant), set up proper traffic control (cones, signs, flaggers per the MUTCD), park vehicles to shield the crew, face oncoming traffic when possible, and use spotters to maintain situational awareness.

What is the ALTA/NSPS Land Title Survey standard, and what is its purpose?

It is a national standard jointly developed by the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS) defining the minimum requirements, accuracy, and optional 'Table A' items for boundary/title surveys used in commercial real estate transactions, ensuring consistency for title insurers and lenders.

In survey standards, what is 'relative positional precision' (relative positional accuracy)?

It is the statistically expected uncertainty (typically at a 95% confidence level) in the position of one survey-established point relative to another, due to random measurement errors. It is a key accuracy metric specified in standards such as the ALTA/NSPS standards.

What is the difference between accuracy and precision in surveying measurements?

Accuracy is the closeness of a measured value to the true value. Precision is the closeness of repeated measurements to one another (repeatability), reflecting the refinement of the measurement regardless of correctness. A measurement can be precise but inaccurate.

What is the difference between a systematic error and a random error in measurement?

A systematic error follows a consistent physical law and biases results in one direction (e.g., tape thermal expansion); it can be modeled and corrected. A random error is small, unpredictable in sign and magnitude, follows probability laws, and cannot be eliminated—only minimized statistically.

What is a blunder (mistake) in surveying, and how does it differ from an error?

A blunder is a gross human mistake (e.g., transposing digits, reading the wrong target, miscounting tape lengths) caused by carelessness or misunderstanding. Unlike systematic and random errors, blunders are not part of normal measurement theory and must be detected and removed, typically through redundant measurements and checks.

State the formula for the standard deviation of a single observation from a set of n direct measurements.

$$\sigma = \sqrt{\frac{\sum_{i=1}^{n}(x_i - \bar{x})^{2}}{n-1}}$$ where $x_i$ are the observations, $\bar{x}$ is the mean, and $n$ is the number of observations.

State the formula for the standard deviation (standard error) of the mean of n observations.

$$\sigma_{\bar{x}} = \frac{\sigma}{\sqrt{n}}$$ where $\sigma$ is the standard deviation of a single observation and $n$ is the number of observations.

How is the precision (ratio) of a traverse closure expressed and computed?

Precision is expressed as a ratio $1:R$, computed as $$\text{Precision} = \frac{\text{linear misclosure}}{\text{total traverse perimeter}}$$ then reduced to the form $1:R$ (e.g., a misclosure of 0.10 ft over a 5000 ft perimeter gives $1:50000$).

What confidence level corresponds to the commonly cited 95% positional tolerance, and roughly how many standard deviations is it?

The 95% confidence level corresponds to approximately $\pm 1.96\sigma$ (often rounded to $\pm 2\sigma$) for a normal distribution. It means there is about a 95% probability the true value lies within that interval.

What is the definition of the U.S. Survey Foot, and how does it differ from the International Foot?

The U.S. Survey Foot is defined as exactly $\frac{1200}{3937}$ meters ($\approx 0.3048006096$ m), while the International Foot equals exactly $0.3048$ m. The difference is about 2 parts per million, which becomes significant over large state-plane coordinate distances.

How many U.S. Survey Feet are in one mile, and how many square feet are in one acre?

There are $5280$ feet in one mile. One acre contains $43560$ square feet (equivalently $\frac{1}{640}$ of a square mile / section).

Convert: how many square feet are in one square mile (one PLSS section), and how many acres?

One square mile (a standard PLSS section) contains $5280^{2} = 27{,}878{,}400$ square feet, which equals $640$ acres.

Define a chain and a link in traditional surveying units, and give their lengths in feet.

A (Gunter's) chain is $66$ feet long and is divided into $100$ links, so one link equals $0.66$ feet ($7.92$ inches). Ten square chains equal one acre ($66 \text{ ft} \times 660 \text{ ft} = 43560 \text{ ft}^2$).

How many degrees, minutes, and seconds are in a circle, and how do you convert degrees to radians?

A full circle has $360°$; each degree has $60$ minutes ($'$) and each minute has $60$ seconds ($''$). To convert degrees to radians: $$\theta_{\text{rad}} = \theta_{\text{deg}} \times \frac{\pi}{180}$$

What is a part-per-million (ppm) error, and express a 5 ppm distance error over a 2000 m line.

A ppm error is a proportional error of one unit per million units of distance. For 5 ppm over 2000 m: $$\text{error} = 2000 \text{ m} \times \frac{5}{1{,}000{,}000} = 0.010 \text{ m} = 10 \text{ mm}.$$

What is the difference between a metes-and-bounds description and a lot-and-block (subdivision) description?

A metes-and-bounds description defines a boundary by sequential courses (bearings/azimuths and distances) and physical/recorded monuments, tracing the perimeter back to a point of beginning. A lot-and-block description references a parcel by its lot and block number on a specific recorded subdivision plat, making it shorter and tied to that map of record.
