PRINCIPLES AND PRACTICE OF SURVEYING
PRACTICE EXAM
1. What is the purpose of a retracement survey in surveying?Answer To reestablish lost corners
and verify the accuracy of existing survey data.
2. What is the significance of the double proportionate measurement in survey- ing?
Answer It is used to reestablish interior section corners by proportioning distances between found corners.
3. How do you calculate the northing coordinate for a lost corner using double
proportionate measurement?Answer Apply the ditterence in northing coordinates for found corners, propor-
tioned by the ratio of record distance from the lost corner to the found corner.
4. What is the formula for determining the easting coordinate using double
proportionate measurement?
Answer E = Ew + (EE - Ew) * (record distance W - lost corner) / (record distance W - E) where Ew is the easting
coordinate of the found corner to the west.
5. What is the northing coordinate calculated for the lost corner in Section 6?
Answer 9984 ft.
,6. What is the easting coordinate calculated for the lost corner in Section 6?
Answer -
15,373 ft.
7. What is the difference between double and single proportionate measure- ment in
surveying?Answer Double proportionate measurement is used for interior corners, while single propor- tionate
measurement is used for exterior corners.
8. What does the abbreviation 'GLO' stand for in surveying?
Answer General Land Oflce.
9. What are the coordinates for the NW corner of Section 6?
Answer 15,300 ft N, 10,000 ft E.
10. What are the coordinates for the SE corner of Section 7?
Answer 15,346 ft N, 20,706 ft E.
11. What is the length of the north line of Section 6 according to the GLO plat?
Answer 80 chains 60 links.
12. How far is the NE corner of Section 5 from the coordinates given?
,Answer 15,334 ft N, 15,207 ft E.
13. What is the record distance for the S line of Section 5?
Answer 80 chains.
14. What is the purpose of using field notes in surveying?
Answer To document measurements and observations made during the survey process.
15. What is the significance of the coordinates provided in a retracement sur- vey?
Answer They help in accurately locating lost corners and verifying existing survey data.
16. What does the term 'section line lengths' refer to in surveying?
Answer The measured distances along the boundaries of sections in a township.
, 17. What is the total record distance between the found corners to the north and south
in the example?
Answer 80 chains.
18. What is the easting coordinate for the found corner to the west in the
example?
Answer 10,000 ft.
19. What is the northing coordinate for the found corner to the south in the
example?
Answer 4667 ft.
20. What is the significance of the 'lost corner' in surveying?
Answer It refers to a corner that cannot be physically located and needs to be reestablished.
21. What does 'ch' stand for in surveying measurements?
Answer Chains.
22. What does 'lks' stand for in surveying measurements?
Answer Links.
