Which term refers to the inner border of a map?

• A. Neatlines
• B. Fix
• C. Graticules
• D. Aphylactic Projection

Answer: (A)

The line that forms the boundary around the mapped area is called the neatline. It marks the inner edge of the map content, giving a clean separation between the data you’re showing and the surrounding margins or frame. Neatlines help with layout and readability by defining exactly where the map ends and the marginal information begins, and in digital work they often serve as a clipping boundary for the data.

Graticules are the latitude and longitude grid lines you see across the map. A fix refers to a determined position in geography or navigation, not the map’s edge. An aphylactic projection isn’t a standard cartography term for the map’s border, so it doesn’t describe the inner boundary.
