Question:

Which method is employed to transform spatial data when changing its dimensionality or position?

Show Hint

Affine transformation performs \[ \boxed{ \text{Translation} + \text{Rotation} + \text{Scaling} + \text{Shearing} } \] It is widely used in GIS image registration and coordinate transformation.

The Correct Option is C

Solution and Explanation

Concept: An affine transformation is a geometric transformation used to change the position, orientation, scale, or shape of spatial data while preserving parallelism.

Step 1:
Understand affine transformation. It includes operations such as
• Translation
• Rotation
• Scaling
• Shearing

Step 2:
Identify the appropriate method. Thus, \[ \boxed{\text{Affine transformation is used to transform spatial data geometrically}.} \] Therefore, the correct option is \[ \boxed{(C).} \]
