thematic map
Let an agent explain thematic maps and their types and techniques, support choosing and designing maps for data, describe historical and cultural thematic maps, and support reading maps critically.
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 explain thematic maps and their types and techniques, support choosing and designing maps for data, describe historical and cultural thematic maps, and support reading maps critically.
A map designed to show the spatial distribution of a particular theme or subject, such as population, climate, land use, political boundaries, historical events, culture or construction, rather than general geographic reference, using techniques such as choropleth shading, dot density, proportional symbols, isolines and flow lines over a base map; thematic maps communicate patterns and are produced in cartography, geographic information systems and data visualisation.
What it is for: Maps showing a specific theme.
It can be explain types and techniques; support design; describe historical examples; support critical reading.
Distinguishing features
Single theme
Data-driven symbolisation
Base map plus theme
Communication purpose
What it looks like
Maps with shaded areas, symbols or lines representing data.
How it is recognised
Map of a particular subject over a base map
Choropleth, dot, proportional symbol, isoline, flow
Reference maps show general features; topographic maps show terrain
