Question 1
Which type of error is often predictable and can be compensated for during measurement?
Correct Answer:
systematic error
Explanation:
Systematic error refers to consistent, predictable inaccuracies that occur in measurements due to flaws in the measurement system, such as calibration issues, environmental factors, or inherent biases in the measurement process. These errors typically affect all measurements in the same way, which allows for them to be identified and compensated for effectively. For instance, if a survey instrument consistently reads a certain value higher or lower due to a calibration issue, the user can apply a correction factor to the measurements to ensure accuracy. This predictability is essential in the surveying field, as it enables surveyors to adjust their data to reflect true values more accurately. In contrast, other types of error like blunders are typically caused by human mistakes, are not predictable, and cannot be systematically compensated for. Random errors involve variations in measurements that occur due to unpredictable fluctuations, making them difficult to correct on a case-by-case basis. Instrument error can also arise from various issues, but it may not always be systematic; it can include both systematic and random components. Thus, systematic error is distinctly characterized by its predictability and the ability to apply corrective measures, emphasizing its importance in ensuring accurate and reliable surveying outcomes.
Question 2
Which term describes the lowest order of calls in a land description hierarchy?
Correct Answer:
Call for distance
Explanation:
The term that describes the lowest order of calls in a land description hierarchy is indeed the call for distance. In survey platting, calls are instructions that indicate how to determine the boundaries of a parcel of land. The hierarchy of calls typically prioritizes different types of calls based on their reliability and specificity. In this hierarchy, calls for natural monuments (like trees or rivers) and artificial monuments (like fences or roads) are more definitive and preferred because they are tangible reference points. When these fixed features are not available, the next tier relies on distance measurements, which become crucial for defining boundaries when no physical markers are present. Thus, the call for distance serves as a lower order because it relies on abstract measurements rather than fixed points. While the calls for area may indicate the size of a parcel, they do not provide direct information about the actual boundaries themselves, which is why they do not take precedence in the hierarchy. Similarly, calls for artificial or natural monuments take precedence over distance calls but do not represent the lowest order. Hence, the call for distance holds the place of the lowest order of calls in this hierarchy of land description.
Question 3
What is the limiting factor when elevations are produced using GNSS?
Correct Answer:
A precise geoid model
Explanation:
When determining elevations using Global Navigation Satellite Systems (GNSS), the critical factor is a precise geoid model. The geoid represents the mean sea level and accounts for variations in the Earth's gravitational field, providing a reference surface from which elevations can be calculated. GNSS primarily provides positional data in terms of ellipsoidal heights based on the Earth's geometric shape. However, to convert these ellipsoidal heights into orthometric heights, which are commonly used in surveying and engineering applications, it is essential to accurately determine the geoid. The use of a precise geoid model allows for the necessary translation from ellipsoidal heights derived from GNSS measurements to the actual physical elevations above sea level. Without an accurate geoid model, the computation of height differences and the representation of terrain elevations would be flawed. While having a clear line of sight is crucial for obtaining accurate GNSS signals, it does not directly influence the accuracy of height determination once the signals are received. A precise ellipsoid model is also important for interpreting GPS data, but it does not facilitate the conversion to orthometric heights without a geoid. A precise gravimetric model relates to gravity measurements and is typically used in conjunction with geoid determination but is not the primary factor when converting GNSS
Question 4
How many pins are in a set of chaining pins?
Correct Answer:
11
Explanation:
In surveying, a standard set of chaining pins typically contains 11 pins. This standardized number helps ensure consistency and accuracy when measuring distances, as the use of uniformly spaced pins allows for reliable chaining practices. Each pin serves a purpose in providing reference points or marking distances, making it crucial to have a complete set for efficient surveying tasks. The set of 11 pins is sufficient for measuring various lengths and allows surveyors to easily manage the number of pins without becoming cumbersome. The additional pins provide redundancy should any pin be lost or damaged during a survey. Having 10 or fewer pins may not offer the same level of flexibility, while a set of 12 or more could lead to unnecessary complexity or burden in the field. Thus, the choice of 11 aligns well with practical field conditions and surveyor needs.
Question 5
Which of the following is NOT a characteristic of a meridian?
Correct Answer:
It measures latitude
Explanation:
A meridian is defined as a line of longitude that runs from the North Pole to the South Pole. Its primary purpose is to help in the determination of longitude, not latitude. Latitude is measured by parallels, which are circles that run parallel to the equator, while meridians intersect these parallels at right angles. Meridians are indeed instrumental in helping to establish time zones, as time is measured based on the position of the sun relative to these lines of longitude. Each time zone is typically defined by a specific meridian, which is essential for standardizing time across different regions. Additionally, meridians serve as crucial references for defining angles in both navigation and cartography, providing a framework to measure angles relative to zero degrees longitude, which is known as the Prime Meridian. Therefore, measuring latitude is not a characteristic of a meridian; rather, it pertains to lines of latitude. This distinction highlights why the option regarding the measurement of latitude is not a characteristic of a meridian.

The FS exam is a closed-book test administered throughout the year at Pearson VUE testing centers. It covers 110 multiple-choice questions over a 6-hour period, which includes a tutorial, a 50-minute break, and a brief survey at the end. The core subjects include: mathematics (like algebra, trigonometry, and calculus), surveying physics, statistics, geodesy, photogrammetry, boundary law, public land surveying systems (PLSS), and business practices. A detailed exam specification is available from NCEES, outlining the exact percentage of questions allocated to each domain.

 

 

What to Expect in the Final Exam

You can expect a professional and controlled environment at the Pearson VUE testing center. The FS exam is a computer-based test (CBT), meaning all questions will be presented on a computer screen. There is no negative marking for incorrect answers, so it's advisable to answer every question. To prepare, familiarize yourself with the NCEES FS Reference Handbook, which is the only reference material you are permitted to use during the exam (and it will be provided to you digitally). You are also allowed to bring a specific list of approved calculators.
