Linear, ratio, and vertical

A linear scale on a map is a graphic representation that shows the relationship between distances on the map and the actual distances on Earth's surface. It usually appears as a line divided into segments that correspond to specific units of measurement, such as miles or kilometers, allowing users to accurately measure distances on the map.

The differences between the these two is that linear scale shows the relation between the map distance and the ground distance. The nonlinear scale do not show the relation between the map distance and the ground distance.
