The Transverse Mercator projection is best suited for states that have what characteristic?

• A. Predominant East-West length
• B. Circular shape
• C. Small areas near the equator
• D. Having a predominant North-South length

Answer: (D)

Transverse Mercator is designed to minimize distortion along a central north–south line, because the projection’s cylinder is oriented to run north–south (transverse) rather than east–west. This setup keeps shapes and distances more accurate along that central meridian, so a region that is tall and narrow—longer in the north–south direction—fits the projection well when the central meridian passes roughly through its center. Distortion then grows as you move east or west away from that line, which means areas that are wider east–west would experience more distortion. A small circular or equatorial area doesn’t align with the way distortion propagates in this projection, so it isn’t as well suited. The key idea is that the Transverse Mercator excels for regions elongated north–south.
