Question

The skew distortion error in images is mainly due to ___________________.
(a.) Rotation of Earth
(b.) Relief Displacement
(c.) Systematic Error
(d.) Orbital Path

Answer 1

Answer:

no.b relief displacement

Answer 2

These errors may be due to a variety of factors, including one or more of the following, to name only a few:

1. the perspective of the sensor optics,
2. the motion of the scanning system,
3. the motion and (in)stability of the platform,
4. the platform altitude, attitude, and velocity,
5. the terrain relief,
6. the curvature and rotation of the Earth.

• Framing systems, such as cameras used for aerial photography, provide an instantaneous "snapshot" view of the Earth from directly overhead. The primary geometric distortion in vertical aerial photographs is due to relief displacement.
