map
Let an agent handle maps by type, scale, projection, date, source, licence and reading skills.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle maps by type, scale, projection, date, source, licence and reading skills.
A symbolic representation, usually two-dimensional, of the features of an area such as land, sea, roads, boundaries or data, drawn to a scale and projection; kinds include topographic, thematic, nautical and digital maps.
What it is for: Navigation, planning, analysis and communication about places.
It can be choose a map type and scale; read scale, legend and grid references; check map date and data source; check licences for reuse.
