Vertical exaggeration is a scale
Scale (ratio)
The scale ratio of some sort of model which represents an original proportionally is the ratio of a linear dimension of the model to the same dimension of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. In such...

Raised-relief map
A raised-relief map or terrain model is a three-dimensional representation, usually of terrain. When representing terrain, the elevation dimension is usually exaggerated by a factor between five and ten; this facilitates the visual recognition of terrain features.-History:In his 1665 paper for the...

perspectives). The exaggeration is used to emphasize vertical features, which might be too small to identify relative to the horizontal scale.

Vertical exaggeration is given as a number; for example 5× means that vertical measurements are 5 times greater than horizontal measurements. A value of 1× indicates that horizontal and vertical scales are identical, and is regarded as having "no vertical exaggeration." Vertical exaggerations less than 1 are not common, but indicate a reduction in vertical scale (or, equivalently, a horizontal exaggeration).
