Adding more colors to your maps

In the previous paragraphs, we encountered some simple maps. Geographers define these kinds of maps as general maps. General maps focus on the description of the physical, political, and human features on the territory. All this data is portrayed for its own sake. In a nutshell, it can be said that general maps tell you where objects are located on the Earth's surface, while thematic maps talk about things happening on the Earth's surface. Thematic maps focus on displaying a single topic and portray spatial distribution and variation. You have general data, such as administrative boundaries or road networks, but this is represented as a base layer for general reference.

Among thematic maps, those using choropleth or dot representations, are by far the most common type you will be using GeoServer for.
