Purpose of Traverse Survey (2.5–3 marks)

1. Establishing Control Points

• Provides a framework of reference points for detailed surveying.

---

2. Boundary Surveying

• Used to determine and fix property boundaries accurately.

---

3. Route Surveying

• Applied in surveys for roads, railways, canals, pipelines, etc.

---

4. Topographic Mapping

• Helps in locating natural and artificial features on maps.

---

5. Construction Work

• Used for setting out engineering projects like buildings and bridges.

---

6. Area Calculation

• Used to compute the area of land parcels.

---

Key Concept

• Traverses can be:
  • Open traverse → does not return to the starting point
  • Closed traverse → forms a closed polygon (more accurate)

Conclusion (1 mark)

Traverse surveying is an important method used to establish control and determine positions of points, making it essential for engineering and mapping works.
