Which three projections are typically used in cartography?

• A. Cylindrical, Conic, Rectangular
• B. Cylindrical, Azimuthal, Conic
• C. Cylindrical, Orthographic, Spherical
• D. Aerial, Azimuthal, Perspective

Answer: (B)

The three projections that are typically used in cartography include cylindrical, azimuthal, and conic projections, making this the correct answer. Cylindrical projections create a map by projecting the world onto a cylinder. This method preserves shapes and angles in a way that can be useful for navigational purposes, especially near the equator, but tends to distort size as one moves toward the poles. Azimuthal projections, on the other hand, present the earth from a certain point, preserving direction and often used for polar maps. This type of projection can be advantageous when depicting air routes or other types of travel, as it provides true directions from the center point. Conic projections are created by projecting the surface of the earth onto a cone. These are commonly used for mid-latitude regions, as they can effectively represent these areas with minimal distortion. The other options include projection types that are not typically recognized in cartography. For instance, rectangular does not refer to a standard projection but rather a general shape, while orthographic refers to a perspective view rather than a true map projection, and aerial refers to a type of imagery rather than a projection method. Thus, the trio of cylindrical, azimuthal, and conic represent
