4.14.1.3. Analytical aerial triangulation

Try these first

1. 1.

   Define Ground Control Points (GCPs).

   Hint

   Think about what anchors the photographs in relation to the ground.

2. 2.

   What are Minor Control Points (MCPs)?

   Hint

   Consider their role in elevation uniformity.

3. 3.

   What is the purpose of Ground Control Points?

   • To hold pictures together
   • To establish accurate positions
   • To provide decoration

   Hint

   Think about what anchors the mapping to reality.

4. 4.

   True or False: Lateral Control Points are unnecessary for overlapping strips.

   • True
   • False

   Hint

   Imagine connecting various photographs together.

5. 5.

   Given a set of photographs with GCPs, outline the steps to perform analytical aerial triangulation from start to finish.

   Hint

   Think about the processes we've just learned.

6. 6.

   In a project with multiple strips of photographs, how can elevation differences cause scaling issues? Propose solutions.

   Hint

   Consider how different heights might distort a flat image.
