TRAVERSE COMPUTATIONS PART 1
Enock・21 minutes read
Students will learn to calculate water preparings for each Travis a lake, determine changes in eastings and noddings, calculate click rates, and adjust total errors in engine loadings. They should also be able to perform arithmetic checks, coordinate migrations, and ensure that angular checks for polygons surveyed add up correctly. Adjustments may be necessary if internal angles do not match the expected value and errors should be evenly distributed among observed angles, with calculations for bearings on different lines based on internal angles and known values.
Insights
- Errors in angles should be equally distributed among observed angles to ensure accuracy in calculations and adjustments.
- Calculations for changes in loadings and eastings are crucial in determining the perimeter of a polygon, with adjustments made to correct errors and achieve a final error of zero, requiring meticulous attention to detail and precision in calculations.

Recent questions
How do students calculate water preparation for a lake?
Students calculate water preparation for a lake by determining the change in eastings and noddings, click rate, total error in engine loadings, arithmetic check, and coordinate migrations. They also perform angular checks for polygons surveyed, ensuring the internal angles add up to n minus 2 times 180 degrees. Adjustments are made if the sum of internal angles does not match the expected value, with errors distributed equally among observed angles. Calculations for bearings on different lines are done using internal angles and known values, based on observed and measured lines in the Travis.
What is the importance of the change in eastings and noddings calculations?
The change in eastings and noddings calculations are crucial for determining the relationship between change initiatives and loadings. Students multiply the distance by the cosine of the bearing angle to calculate the change in loadings, and by the sine of the bearing angle for the change in eastings. Specific distances and bearings provided for various lines aid in these calculations, ensuring errors are identified and corrected by adjusting the values of changing loadings and eastings.
How are errors in angle calculations addressed?
Errors in angle calculations are addressed by ensuring the internal angles of a polygon add up to n minus 2 times 180 degrees. If the total sum of internal angles does not match the expected value, adjustments are made to distribute errors equally among the observed angles. The process involves determining the perimeter of the polygon traversed, adding all travesty legs, changes in eastings, and loadings, aiming for a final error of zero through adjustments.
What is the process for verifying the accuracy of calculations in surveying?
The process for verifying the accuracy of calculations in surveying involves performing arithmetic checks, coordinate migrations, and angular checks for polygons surveyed. Internal angles of a polygon should add up to n minus 2 times 180 degrees, with adjustments made if the total sum of internal angles does not match the expected value. Errors in angles are distributed equally among observed angles, and calculations for bearings on different lines are done using internal angles and known values.
How are changes in loadings and eastings calculated in surveying?
Changes in loadings and eastings are calculated in surveying by multiplying the distance by the cosine of the bearing angle for the change in loadings, and by the sine of the bearing angle for the change in eastings. Specific distances and bearings provided for various lines aid in these calculations, with errors identified and corrected by adjusting the values of changing loadings and eastings. The relationship between change initiatives and loadings is determined by the exercise, with the change in noddings being crucial for accurate calculations.
