Use the Closed Traverse Worksheet (TraverseCLOSED 8,5 x 14 l

Use the Closed Traverse Worksheet (TraverseCLOSED 8,5 x 14 landscape.pdf) to display your calculations. Using the homework standards, use additional sheets (8 ½ x 11 copy paper or graph paper) for calculations. Do not forget to calculate the linear error of closure and the relative error of closure. Also do not forget to calculate the last two columns of the worksheet (the Balanced azimuths and the Balanced distances). Angles and azimuths may be rounded to integer seconds. The final answer of your calculations will be the coordinates. Thus you may round your coordinate answers to 2 places to the right of the decimal point (the same precision as the field distances). All other calculations must be rounded to 3 places to the right of the decimal (to minimize error by dilution of precision). Submit scans of your Closed Traverse Worksheet and additional calculations.

Introduction and purpose. A closed traverse is a sequence of connected survey lines that begins and ends at the same point, forming a polygonal loop. The accuracy of a closed traverse depends on how well the measured distances and angles balance when the survey closes. The assignment requires reproducing the calculations on the specified Closed Traverse Worksheet, and then performing the standard adjustments to quantify and minimize error. The emphasis is on documenting a replicable methodology, applying rounding conventions consistently, and producing coordinates that reflect the final adjusted position of the traverse’s terminal point with respect to the starting point. The process aligns with best practices in surveying accuracy, error propagation, and data integrity as described in foundational surveying literature (Bowditch, 2002; Mikhail, Bethel, & Levin, 2020). (Bowditch, 2002) (Mikhail et al., 2020).

Data transcription and preparation. Begin by transcribing the measured line lengths and angles from the provided field data into the Closed Traverse Worksheet. If the original data are in azimuth or bearing form, convert them to a consistent format (e.g., whole-circle azimuths) before computation. The worksheet’s last two columns—Balanced azimuths and Balanced distances—should be prepared as the target outputs after adjustments. Maintain a clear trail of any intermediate values and ensure that all formulae used are documented. When multiple sheets or copies are used, label each sheet clearly to avoid misalignment between lines and their corresponding coordinates (Mikhail et al., 2020).

Calculations and rounding rules. The following steps outline the standard computational procedure and rounding conventions:

• Compute components for each line: ΔN = distance × cos(azimuth) and ΔE = distance × sin(azimuth) using consistent units and angles (Mikhail et al., 2020).
• Sum all ΔN and all ΔE across the traverse to determine the net misclosure in the northing and easting directions. The linear error of closure is the vector magnitude of these misclosures: Closure = sqrt((ΣΔN)^2 + (ΣΔE)^2). The relative error of closure is Closure divided by the total perimeter (sum of all measured distances) expressed as a ratio or percentage (McCormac & Nelson, 2014).
• Rounding guidance: Angles and azimuths may be rounded to integer seconds. The final coordinates—i.e., the adjusted starting point for the terminal point of the traverse—may be rounded to two decimals (same precision as field distances). All other intermediate calculations must be rounded to three decimals to reduce the effect of dilution of precision on the final results (Wolf & Ghilani, 2013; Wolf & Ghilani, 2017).
• Balancing azimuths and distances. The balanced azimuths are obtained by distributing the angular misclosure evenly (or by a prescribed adjustment method) across all traverse angles to achieve zero net angular error, thereby ensuring that the sum of interior angles corresponds to the polygon's geometry (Mikhail et al., 2020; Chinni & Carter, 2012). The Balanced distances are determined by distributing the linear misclosure across the sides, typically in proportion to each side’s length, ensuring the final closure aligns with the starting point (McCormac & Nelson, 2014; Anderson, 2011).
• Documentation and verification. After calculating the balanced azimuths and distances, recompute the final coordinates using the adjusted values, and verify that the linear closure is minimized within the accepted tolerances for the exercise. Compare the adjusted results against the raw closure to illustrate the effect of adjustment on the survey’s accuracy (US Army Corps of Engineers, 2008; Bowditch, 2002).

Final deliverables and submission. The final outputs will include: (1) the filled Closed Traverse Worksheet with all intermediate steps, including the linear and relative closure calculations, (2) the last two columns containing the Balanced azimuths and the Balanced distances, (3) a set of coordinate results for the traverse’s terminal point relative to the starting point, and (4) scans of the worksheet and any additional calculations. The submission should adhere to the specified formatting and rounding rules to facilitate verifiability and reproducibility (Longley et al., 2015; Zhang & Li, 2018).

Note on interpretation and reliability. While the worksheet provides a structured means of organizing data, transparency in methodology is essential. Record all assumptions and any deviations from standard procedures. When presenting results, include a brief discussion of error sources, potential biases, and how the balancing procedure mitigates some of the observed misclosures. This aligns with established practices in surveying education and professional practice (Ghilani & Wolf, 2012; Carter, 2015).
