why do we calculate vertical exaggeration

by Madaline Stracke Published 3 years ago Updated 3 years ago

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

What does a vertical exaggeration of 1× mean?

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 would indicate a reduction in vertical scale (or, equivalently, a horizontal exaggeration).

What is the scaling factor of vertical exaggeration?

Scaling Factor. The vertical exaggeration is given by: where VS is the vertical scale and HS is the horizontal scale, both given as representative fractions. For example, if 1 centimetre (0.39 in) vertically represents 200 metres (660 ft) and 1 centimetre (0.39 in) horizontally represents 4,000 metres (13,000 ft), the vertical exaggeration,...

Why do scientists object to vertical exaggeration?

Some scientists object to vertical exaggeration as a tool that makes an oblique visualization dramatic at the cost of misleading the viewer about the true appearance of the landscape. ^ David Morrison, " “Flat‐Venus Society” organizes ", EOS, Volume 73, Issue 9, American Geophysical Union, 3 March 1992, p.

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 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.

How do we calculate vertical exaggeration?

This is because if both axes were done to the same scale the vertical scale on the y axisMoreScale. This is because if both axes were done to the same scale the vertical scale on the y axis would appear almost flat to calculate the vertical exaggeration of a cross.

What is the purpose of vertical exaggeration on profiles of the sea floor?

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 are the advantages and disadvantages of the amount of vertical exaggeration?

The main advantage is that it is easier to understand and see the shape of the hill or this profile. The main disadvantage is that the apparent relief of the hill is now very unrealistic (also, the scale changes so the profile looks a bit different because it's exaggerated - you must be aware of the changes).

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 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 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.

Why is the geological cross section important?

Geologic cross sections provided two-dimensional slice of Earth's subsurface and is used to help understand geologic conditions that occur in specific areas of the cross section. Creating and evaluating cross-section is a very important aspect of the geoscience profession.

Why do objects appear vertically exaggerated in stereoscopic viewing?

Stereoscopic causes of vertical exaggeration are: a. Viewing Distance. As viewing distance increases the horizontal scale of the stereoscopic model decreases, while the vertical scale remains nearly con- stant with a resulting- increase in vertical exaggeration.
