Which symbol is used on maps to represent class 1 buildings?

• A. An area shown with a solid or crosshatch print
• B. An open outline or single hatch
• C. A red fill
• D. Blue shading

Answer: (A)

On maps, how built-up areas are shown depends on the legend style. For class 1 buildings, the symbol uses an area fill—either solid or crosshatch—to indicate that within that space there are buildings of that class. This compact, filled area communicates a cluster of structures clearly and is easy to read at a glance, especially in dense regions. An open outline or a single hatch usually marks boundaries or a different type of feature, not a concentration of buildings in a specific class. Red fill or blue shading tends to signify other meanings like hazards or non-building features. So the solid or crosshatched area fill best conveys the presence of class 1 buildings on the map.
