Which map emphasizes a single idea or a particular kind of information about an area, such as choropleth or proportional symbol?

• A. Toponym
• B. Site
• C. Sustainability
• D. Thematic Map

Answer: (D)

A map that emphasizes a single idea or a particular kind of information about an area is a thematic map. Thematic maps are built to highlight data patterns for one topic, using colors or symbols to reveal how a variable varies across space. For example, choropleth maps shade regions by data values, and proportional symbol maps use the size of symbols to indicate magnitude—all to show the theme clearly. A toponym map focuses on place names rather than showing a single data theme. A site map concentrates on the exact location or layout of features, not on a thematic pattern. And sustainability isn’t a map type at all but a topic or goal. So the option described is a thematic map.
