Which term describes a projection orientation that is rotated 90 degrees from the standard orientation?

• A. Normal
• B. Transverse
• C. Orthographic
• D. Oblique

Answer: (B)

Transverse refers to an orientation that is rotated by 90 degrees from the standard setup, so the reference line that runs along a meridian takes the place of the usual equatorial reference. In map projections, the normal (standard) orientation has the equator as the primary reference, but when you rotate the projection so a meridian becomes the central reference line, you get a transverse projection. This is the idea behind the name: the projection is aligned across the usual orientation. Orthographic describes a specific way of viewing or projecting a globe onto a plane, not a rotated orientation; oblique means the projection is rotated by some angle other than 0 or 90 degrees; normal is simply the standard orientation.
