Aug 31, 2023 · A thematic map is a type of map used to visually display geospatial data (data related to a certain location) based on a specific theme or topic. Thematic maps can help visualize the distribution of data related to population, election results, weather measurements and more within a designated area.
- Choropleth Maps. Choropleth maps represent data values in geographic areas with different colors and patterns. Data is categorized into classes, with each class assigned a unique color or pattern.
- Dot Density Maps. These maps represent each data point with a dot and are a great way to measure density. Regions with a large number of dots packed close to together are easily identified as high-density areas, whereas regions with few or no dots are clearly areas where your data is lacking.
- Isopleth Maps. Isopleth maps use colors and shades to represent data, similar to choropleth maps. However, they differ in that data isn’t grouped within predefined boundaries such as census tracts, counties, or states.
- Heat Maps. Heat maps measure density across a map. Like many other map types, they represent data using color. Darker shades indicate higher density areas while lighter shades show lower density areas.
A thematic map is a type of map that portrays the geographic pattern of a particular subject matter (theme) in a geographic area. This usually involves the use of map symbols to visualize selected properties of geographic features that are not naturally visible, such as temperature, language, or population. [1]
Jul 10, 2019 · By Amanda Briney. Halley's maps were largely used for navigation and study of the physical environment. In 1854, London doctor John Snow created the first thematic map used for problem analysis when he mapped cholera's spread throughout the city. He began with a base map of London's neighborhoods that included streets and water pump locations.

- Choropleth maps. Choropleth maps use color density or shading to depict differences in statistical values over a geographic area. Darker shades represent higher measured values, while lighter shades indicate lower values.
- Heat maps. Heat maps also use color to represent data variable intensity but with more of a continuous color gradient. Like weather maps, which show temperature variations across a region, heat maps leverage a color scale to visually depict the density or concentration of a particular metric within a given area.
- Bubble maps. Unlike choropleth and heat maps, bubble maps use proportional symbols rather than color to depict variances in the mapped variable. Typically, the bubbles are scaled directly to the data attribute value, so a region with double the value would display a bubble twice the size.
- Radius maps. Radius maps illustrate information about geographic points within a defined radius area. The radius boundary is typically centered around focus locations (such as existing stores).
Oct 16, 2023 · 1. Choropleth Maps. Choropleth maps use shading or coloring to represent statistical data. These maps are incredibly effective at displaying population densities, election results, or any data that can be categorized by region. 2. Dot Distribution Maps.
