Map Types

Dot maps use dots to show the density of a particular phenomenon in an area. More dots represent a higher density compared to fewer dots.

The drive time map is a type of isochrone map that shows you how far you can go based on a start location and an allotted amount of time.

Space-time cubes show how phenomena change over time within geographic space. In a space-time cube, each cube represents a slice of time.

While graduated symbols and proportional symbols scale the size of the symbol based on value, dot distribution maps use dots for quantity.

Cartographers use lines to show the movement of phenomenon in flow maps. To show the magnitude, they change the width of flow lines.

Cartogram maps distorts reality to convey information. It accomplishes this by resizing and exaggerating any variable using a polygons geometry.

In a Voronoi Diagram, when you take a point in any given Thiessen polygon, it indicates that it’s closer to that generating point than to any other.
