Vertical exaggeration is a scale used primarily in the field of geography but also in engineering. It emphasizes certain terrain features or objects by making them larger, ergo increasing their overall visibility. It all sounds overly complicated, so let’s bring some visualizations to make things more straightforward.
What is vertical exaggeration on a map?
In reality, the terrain would appear much flatter. Vertical exaggeration ( VE) is a scale that is used in raised-relief maps, plans and technical drawings ( cross section perspectives), in order to emphasize vertical features, which might be too small to identify relative to the horizontal scale.
What is the vertical exaggeration in the middle ground (green)?
In the middle ground (green) the vertical exaggeration is 2. In the background (red), the vertical exaggeration is 5.
Should I use vertical exaggeration when constructing a topographic profile?
Depending on why you are creating your topographic profile, you may want to use vertical exaggeration when constructing it.
What is a vertically exaggerated mountain called?
A vertically exaggerated mountain. In reality, the terrain would appear much flatter. Vertical exaggeration ( VE) is a scale that is used in raised-relief maps, plans and technical drawings ( cross section perspectives), in order to emphasize vertical features, which might be too small to identify relative to the horizontal scale.

What is meant by vertical exaggeration?
Vertical exaggeration refers to the common practice in topographic profiles of different horizontal and vertical scales. It is expressed as a number, the ratio of the vertical to horizontal scale, and is almost always greater than 1.
What is the difference between gradient and vertical exaggeration?
The gradient of 1:126.5 means that for every 126.5, units that you travel horizontally, there will be an elevation of 1 unit. The vertical exaggeration is the size by which the vertical scale of a cross section is bigger than the horizontal scale.
What is the value for vertical exaggeration?
A value higher than 1× indicates vertical exaggeration, e.g., 10× means that vertical measurements are ten times greater than horizontal measurements; A value equal to 1× implies no vertical exaggeration; and. A value lower than 1× means horizontal exaggeration, the opposite of vertical exaggeration.
What is vertical exaggeration quizlet?
vertical exaggeration. the ratio of the vertical scale divided by the horizontal scale. A ratio of one means a scale that shows the accurate bottom. Values are usually much greater than one and make the vertical features appear much more dramatic than they really are. Bathymetry.
What is vertical exaggeration and how do we use it in oceanography?
Vertical exaggeration helps maximize the utility of cross- sections, especially across large distances. Earth's surface is relatively smooth; if Earth were an egg, the crust of can be equated to the thickness of the eggshell. As a result, cross sections often use vertical exaggeration to show near-surface features.
What is a vertical exaggeration topographic map?
Vertical exaggeration (VE) is a scale that is used in raised-relief maps, plans and technical drawings (cross section perspectives), in order to emphasize vertical features, which might be too small to identify relative to the horizontal scale.
How do you make a vertical exaggeration topographic profile?
In order to calculate vertical exaggeration, divide the real world units of horizontal scale by the real world units of vertical scale. Make sure same units are used in numerator and denominator of the division. Also always show vertical exaggeration value on your profile graph.
What is vertical exaggeration in stereoscopy?
Vertical exaggeration is the change in a model surface created by propor- tionally raising the apparent height of all points above the base level while re- taining the same base scale (Figure 1). This is a constant factor throughout the stereoscopic model.
How do you increase vertical exaggeration on Google Earth?
To do this, click Tools > Options > 3D View from the Tools menu (for the Mac, choose Google Earth > Preferences > 3D View) and change the Elevation Exaggeration figure. You can set it to any value from 1 to 3, including decimal points.
How do you find the vertical and horizontal scale?
MAKE SURE YOU SEE THE DIFFERENCE!vertical scaling: going from y=f(x) y = f ( x ) to y=kf(x) y = k f ( x ) for k>0.horizontal scaling: going from y=f(x) y = f ( x ) to y=f(kx) y = f ( k x ) for k>0.Make sure you see the difference between (say) y=3f(x) y = 3 f ( x ) and y=f(3x) y = f ( 3 x ) !
What is vertical exaggeration in photogrammetry?
WHAT IS VERTICAL EXAGGERATION? When one looks at overlapping vertical aerial photographs through a refraction stereoscope, he sees a three-dimensional model whose vertical scale exceeds the horizontal. Such a model, or mental image, is said to be vertically exaggerated.

What is vertical exaggeration?
Vertical exaggeration ( VE) is a scale that is used in raised-relief maps, plans and technical drawings ( cross section perspectives), in order to emphasize vertical features, which might be too small to identify relative to the horizontal scale.
What does it mean when a vertical exaggeration is less than 1?
Vertical exaggerations less than 1 are not common, but would indicate a reduction in vertical scale (or, equivalently, a horizontal exaggeration). In some cases, if the vertical exaggeration is too high, the map reader may get confused.
