A map showing general information used as a base upon which thematic map information is added is called what?

A base map provides the general geographic context that everything else is built upon. It offers the essential framework—locations, boundaries, roads, rivers, landforms, scale, and projection—so you can accurately place and compare the thematic information you want to display. Thematic data are layered on top of this foundational map to reveal patterns or relationships, while the base map itself stays as the stable backdrop. Other types of maps focus on a specific theme (such as geology or a particular topic) and aren’t meant to serve as the general spatial framework for multiple thematic layers, which is why this map is the base map.
