Restoration of Lost Corners by Proportionate Measurement

Section 2 - Review Exercise

1. If a section or township boundary has a deflection in alignment, what would we call this boundary line?

2. What may create such a misalignment?

3. If a corner(s) is (are) lost along such a boundary, what assumption must we make regarding any retracement?

4. On a meridional line, the latitude of the closing distance is distributed among the courses in:

5. Applying the above single proportion concept and the "compass rule," complete the following formulas using the labels and diagram below:

d (a) ___ = ___ D (b)	x (c) ___ = ___ x+y (d)	(a) =	(b) =	(c) =	(d) =
d (a) ___ = ___ D (b)	x (c) ___ = ___ x+y (d)	a. D b. d1 c. L d. D1	a. D b. D1 c. L d. d1	a. D b. L1 c. L d. D1	a. D b. d1 c. L d. D1

6. What special consideration must be applied when resurveying a township or boundary line that runs east or west?

7. Here is a township border with a lost corner. A retracement using record data was run. Compute the proportional bearings and distances.
