Why do we calculate 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.
Vertical exaggeration is necessary to interpret line of sight profiles, but must be considered before jumping to conclusions about trafficability up slopes. A true scale profile is only possible over short distances with very steep topography.Feb 27, 2016

How do you calculate vertical exaggeration?
Aug 21, 2020 · 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.
Why is there a need for vertical exaggeration in elevation profiles?

Click to see full answer.
What is the ratio of vertical exaggeration to pixels?
It's all got to do with profiles! Vertical exaggeration is a comparison between the horizontal and vertical scales on a profile. Its value is gotten by taking what a unit, such as an inch, represents on the horizontal scale and dividing it by what that unit represents on the vertical scale. In the diagram on the right, 1" = 100' on both the vertical and horizontal scales.
What is the purpose of 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.
Why is vertical exaggeration useful when studying the seafloor?
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.Apr 7, 2017
How do we calculate vertical exaggeration?
Vertical exaggeration is a comparison between the horizontal and vertical scales on a profile. Its value is gotten by taking what a unit, such as an inch, represents on the horizontal scale and dividing it by what that unit represents on the vertical scale.
How is vertical exaggeration calculated on a topographic profile?
Vertical exaggeration formula: VE = (real world units of horizontal scale) / (real world units of vertical scale). As an example for a 1:50000 topographic map, we can set the horizontal scale (x axis) of the profile the same as the map.Sep 2, 2013
What is the purpose of Oceanography?
Oceanography applies chemistry, geology, meteorology, biology, and other branches of science to the study of the ocean. It is especially important today as climate change, pollution, and other factors are threatening the ocean and its marine life.Oct 24, 2019
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 does a vertical profile show?
The Vertical Profile Display Control shows a plot of any number of field values versus altitude.
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.
How do I exaggerate topography in 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. A common setting is 1.5, which achieves an obvious yet natural elevation appearance.
What is the vertical scale on a graph?
Scaling is a process of changing the shape and size of the graph of the function. Vertical scaling refers to changing the shape and size of the graph of the function along the y-axis and is done by multiplying the function by some constant.
How can a person measure distance and elevation on a topographic map to create a vertical profile?
You can figure out the elevation of any point by finding the nearest labeled line, counting the number of lines above or below it, multiplying by the contour interval, and adding or subtracting the result from the nearest marked contour line. The more closely spaced the contour lines, the steeper the slope.
What are lines of equal depth called?
Isobath. A line representing points of equal depth under water.Jun 30, 2019
Why is this relevant? How is it used?
Cross section maps typically exaggerate (make bigger) the vertical scale by comparison to the horizontal scale in order to make landforms visible. This exaggeration changes the shape of the map.

What does 1x mean in a profile graph?
A value of 1x for VE means that there is no vertical exaggeration and the vertical and horizontal scales are equal. A VE value less than 1 actually denotes a horizontal exaggeration which has the effect of smoothing the profile graph.
What is elevation profile?
An elevation profile or a topographic profile is a two-dimensional cross sectional view of the landscape. It provides a side view of the relief of the terrain along a line drawn between two locations on a topographic map.
What does a VE less than 1 mean?
A VE value less than 1 actually denotes a horizontal exaggeration which has the effect of smoothing the profile graph. (Note that the numbers corresponding to measurements on the image may be different on your computer monitor due to resolution difference or when the image is printed.

A cross section with a bigger vertical exaggeration will be taller on the vertical access than a cross section with a smaller vertical exaggeration. The answer for VE is just a number (like 5) which means that the vertical scale is 5 times bigger than the horizontal scale. Calculating. To calculate VE, ie is the vert scale divided by the horizontal scale.

You can always select a smaller vertical exaggeration, but may get pancake topography. Vertical exaggeration is necessary to interpret line of sight profiles, but must be considered before jumping to conclusions about trafficability up slopes. A true scale profile is only possible over short distances with very steep topography.

Vertical exaggeration is often used if you want to discern subtle topographic features or if the profile covers a large horizontal distance (miles) relative to the relief (feet). To determine the amount of vertical exaggeration used to construct a profile, simply divide the real-world units on the horizontal axis by the real-world units on the vertical axis.
