What is the purpose of neat lines on a quadrangle map?

• A. The boundaries of quadrangle maps that make the maps look neat
• B. To indicate elevation
• C. To show political boundaries
• D. To label features

Answer: (A)

Neat lines define the edge of the map, giving a tidy rectangular frame that marks the exact extent of what is shown on the sheet. This boundary makes it easy to line up and stack multiple quadrangle maps, ensures a consistent margin for printing or cropping, and shows clearly where the mapped area ends. Inside this frame you’ll find elevation, features, and labels, all arranged relative to that boundary. They aren’t used to show elevation themselves, nor to indicate political boundaries or to label features.
