4.14.1.1. Radial Triangulation

Try these first

1. 1.

   What is radial triangulation?

   Hint

   Think about how angles help in measurements.

2. 2.

   Identify one key feature of a principal point.

   Hint

   Consider its role in the triangulation process.

3. 3.

   What technique is essential for determining 3D coordinates using aerial photographs?

   • Lateral adjustment
   • Radial triangulation
   • Vector computation

   Hint

   Think about the proper method used in aerial mapping.

4. 4.

   True or False: Control points must be evenly distributed for effective measurements.

   • True
   • False

   Hint

   Consider the impact of spacing in triangulation accuracy.

5. 5.

   You need to establish new control points in a hilly area for a mapping project. Explain the steps and considerations you would take in using radial triangulation here.

   Hint

   Think about both visibility and accessibility of your control points.

6. 6.

   How would you adapt radial triangulation methods to a scenario where aerial photographs are taken in varying weather conditions leading to inconsistencies?

   Hint

   Consider how external conditions can affect the accuracy of your measurements.
