Cartographic Silence

Cartographic silence is the systematic omission of information from a map or representational system — not by accident, but by the structural choices of what to include, what to prioritize, and what to render invisible. The concept, developed by cartographic historian J.B. Harley and extended into information ethics, recognizes that every map performs an epistemic surgery: it cuts away whatever its makers consider irrelevant, and in doing so, it shapes what can be known about a territory.

The silence is not neutral. A map that omits indigenous place names, informal settlements, or ecological relationships encodes a specific claim about what matters and who gets to name reality. These omissions constitute a form of epistemic injustice — not interpersonal prejudice, but cartographic power operating through the very medium of representation. The blank spaces on a map are not empty; they are arguments.
