General Navigation USCG Question #255 (Set 9)

In very high latitudes, the most practical chart projection is the __________.

Official USCG Answer & Rule Citation

Correct Answer: Option A — Lambert conformal

Lambert conformal projections are ideal for high latitudes because they maintain constant scale and angular relationships over large areas. Unlike the Mercator projection, which suffers from extreme distortion near the poles, the Lambert conformal projection minimizes scale error, making it the standard choice for polar and high-latitude navigation.
