A single symbol label thematic map refers to a label thematic map that, based on a thematic variable (property field or mathematical expression of fields), performs text labeling on objects in the vector layer used to create the label thematic map. The labeling content is the thematic value corresponding to each object, and all objects use a uniform text style, meaning all text in the label thematic map adopts a specified display style.

In the mapping process, single symbol label thematic maps are often used to label provincial and prefectural-level administrative regions in national maps.
