| Cartogram | sizes are shown according to some specific statistic |
| Spatial Patterns | general physical arrangement of things being studied |
| Reference Maps | designed for people to refer to to get general info about a place |
| Thematic Maps | show spatial aspects of information or a phenomenon |
| Choropleth Maps | use various colors, shades of one color, or patterns to show the location and distribution of spatial data |
| Dot Distribution Maps | used to show the specific location and distribution of something across the territory of a map; each dot represents a specified quantity |
| Graduated Symbol Maps | uses map symbols that vary in size to represent different amounts of something; also known as Graduated Circle/Proportional Symbol Map |
| Isoline Maps | lines drawn on a map to connect points of equal value; ex: topographic maps (show elevation) or weather maps (show average precipitation, temperature) |
