The _______________ splits light into it's component color to be read by the CCD sensor triplet. -
Answers Trichord prism
These views project at right angles from the datum, as if viewing from an infinite height. -
Answers Orthographic Views
Pattern, size and shape are all example of what kind of electromagnetic field variations that can
be used to identify and characterize objects? - Answers Spatial
The effect whereby the position or direction of an object appears to differ when viewed from
different positions, e.g. through the viewfinder and the lens of a camera. - Answers Parallax
Positive and negative spherical distortion are examples of: - Answers Radial Lens Distortion
Change in the viewing distance to the terrain, caused by tilt, is called: - Answers Perspective
Distortion
What type of imagery records from 0.4 micrometers up to 0.7 micrometers in a single band. -
