  Section 1 - Sample Problem

This is only one example. There are many other conditions where this adjustment might be used. The next question is; How is the nonriparian broken boundary adjustment computed? There's more than one approach to computing this adjustment, but for the sake of simplicity, only one will be presented in this program. Here's an example of the nonriparian broken boundary adjustment without the numerical bearings and distances.





At the end of record courses, we have a tie to the objective found corner. In this example, where the actual record courses were run, the tie from the end of the record courses to the objective corner is the closing error.






Next, the amount of closing error in latitude and departure is distributed among the record courses according to their lengths. The true line bearings and distances are then obtained by connecting the true positions of the corners. Now, let's do a problem.
