What does the Series refer to on a quadrangle map?

• A. The mapped area in degrees, minutes, and seconds
• B. The map's projection type
• C. The cartographer's initials
• D. The map's scale

Answer: (A)

The Series line on a quadrangle map identifies the geographic extent of that sheet, described in degrees, minutes, and seconds. This is how the map communicates the exact chunk of the globe it covers, so you can place it in relation to neighboring sheets or a larger geographic grid. It isn’t about how the map is projected, who created it, or the map’s scale—those details are shown elsewhere on the map. Knowing the extent helps you quickly understand which area you’re looking at and where it sits in a broader series of maps.
