Which term best describes the set of maps that includes cadastral, municipal base maps, provincial base maps, and regional base maps?

• A. Thematic Base Maps
• B. Topographic Base Maps
• C. Administrative Base Maps
• D. Standard Base Maps

Answer: (D)

Base maps are the foundational reference layers used for all mapping work. The set described—cadastral, municipal base maps, provincial base maps, regional base maps—represents standardized reference layers across multiple levels of administration. They’re designed to align with each other in projection, scale, and metadata so parcel data can be integrated with higher-level boundaries. Because they are the conventional, broadly used framework that is shared across projects and agencies, they are called standard base maps. Thematic base maps are organized by a theme rather than being a consistent reference framework; topographic base maps center on terrain and elevation; administrative base maps may cover boundaries but don’t by themselves imply the standardized cross-scale suite that cadastral up to regional maps represent. Hence standard base maps is the best description.
