READ THE MAP.
QUESTION THE STORY.

A map is easier to use when you can explain its symbols, sources, extent, and purpose. This topic collects guides that develop those habits across everyday basemaps, historical sheets, route interpretation, and the wider cartography workflow. Read them as complementary ways to ask what a representation shows—and what it leaves unresolved.

For a first exercise, choose one map and describe the decision it supports in a single sentence. Then identify the important labels, the source information, and one uncertainty that a reader should not have to guess. Use the field guides below to refine that explanation. The aim is not to distrust every map, but to become more precise about the questions a particular map can answer and the context it needs to remain useful.
