Map
Definition
A visual representation of geographic areas showing locations, boundaries, or spatial relationships. Similar to the category Charts, the category Maps combination of geographic representation with analytical intent makes variations of map types effectively limitless – ranging from traditional cartographic projections to highly stylized or data-driven visualizations. For accessibility purposes, it is useful to consider the intent of the spatial information depicted. Common objectives include: showing physical geography or topography; depicting political or administrative boundaries; illustrating movement or flow across space; representing distributions or densities of variables; revealing networks and connectivity; or conveying historical, linguistic, or cultural patterns. Some maps serve multiple purposes simultaneously, so authors should identify the key spatial relationships the map is designed to illustrate and write image descriptions that summarize the essential relationships, patterns, or comparisons.
