How are class 2 buildings depicted on maps?

• A. An open outline or a single hatch with diagonal (NE-SW) direction
• B. A solid fill
• C. A dotted circle
• D. A blue stripe

Answer: (A)

In map reading, different features and categories are shown with symbols and patterns so you can distinguish them quickly without crowding the map. For buildings that belong to a specific class, the convention is to use an open outline or a single hatch rather than filling the shape in. This keeps the footprint of the building visible and preserves underlying details like roads, labels, and terrain.

The diagonal hatch, running from NE to SW, gives a clear, consistent cue that this building belongs to that particular class, while still letting the map remain readable. A solid fill would obscure nearby features and labels, a dotted circle isn’t a typical way to represent building footprints, and a blue stripe would usually indicate something like water or a boundary, not buildings. So the open outline or diagonal hatch is the best way to depict class 2 buildings.
