Vertical exaggeration is a common practice used to display information in profile view. In most places, the earth is relatively flat, and changes in elevation are subtle. To make the peaks and valleys stand out a bit more, the elevations are exaggerated while the horizontal distances are kept the same.
What is vertical exaggeration in topographic profile?
Available with 3D Analyst license. Vertical exaggeration can be used to emphasize subtle changes in a surface. This can be useful in creating visualizations of terrain where the horizontal extent of the surface is significantly greater than the amount of vertical change in the surface.
How is vertical exaggeration for a vertical profile calculated?
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.
Why is using vertical exaggeration on vertical cross sections of the ocean floor important?
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 does a vertical profile show geology?
Topo Map Elevation Profile - Vertical Exaggeration. 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 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. Cross sections are always drawn with some vertical exaggeration.
What is vertical exaggeration quizlet?
What is vertical exaggeration? The ratio of the horizontal scale on a map to the vertical scale on a map.
What is the cross section of vertical exaggeration?

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 calculating vertical exaggeration important?
So, to summarize, vertical exaggeration allows us to increase the readability of raised-relief (three-dimensional) maps and technical drawings by modifying the height of certain areas or objects.
What is the exaggeration factor?
The exaggeration attribute may be used to exaggerate or multiply the length of certain types of Line objects when they are passed to a CAD file. Note that exaggeration factor may only be used with Radiation or Offset objects. The default exaggeration factor is 1.
What is exaggeration in cartography?
Exaggerate. Exaggeration being used to maintain shape of land at small scale. The original landform appears to break into two pieces when viewed at a smaller scale.
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 quizlet?
What is vertical exaggeration? The ratio of the horizontal scale on a map to the vertical scale on a map.
How do I figure out my vertical?
Measure the height of your standing mark. Measure the height of your highest jump. Subtract your standing height from your highest jump. This number is your vertical jump.

What are the most common exaggeration values?
The three most common exaggeration values that I've seen are 1 (not exaggerated at all), 2 & 10.
How does a profile work?
The profiles work by setting a an EXAGGERATION VALUE in the style. This factor is multiplied by your current drawing scale. The file that you've posted has an exaggeration value of 5. Given your current horizontal scale of 1"=40', that means that the vertical scale will be 1"=8'.
What is auto suggest?
Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Does C3D always have the same exaggeration value?
Since the first time I ever used C3D (2012), the exaggeration value has always remained constant when changing the horizontal scale in every version I've ever used. Honestly, I wouldn't want it any other way -- this way the profiles always look the same except for the scale changes.
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.
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.
How to plot elevation on a graph paper?
Place the edge of the paper along the x-axis of a graph paper. Note the minimum and maximum elevations along the line you've recorded. Label the graph's y-axis with elevation values ensuring that they encompass the minimum and maximum values recorded previously. Therefore the x-axis corresponds to the horizontal distance of the line on map. The y-axis represents the elevation of points along the line. On the graph paper, plot the corresponding elevation above each tick mark. By connecting the dots, the elevation profile along the line of interest is drawn.
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.
How to draw a topographic profile?
In order to draw a topographic profile along a desired line on a topo map, put the straight edge of a piece of paper between the end points of the line. Mark with a tick mark on the edge of the paper wherever the paper crosses a contour line. Label each tick mark with the elevation of the corresponding contour line.
Can you draw a path in Geokov?
You can also draw a desired path in Geokov Map Maker on a topographic map or Google Maps base maps. The drawing can then be exported in the form of a kml file. Save the file with .kml extension, and import it to Google Earth. Proceed as above to draw the path's elevation profile.
Do profile graphs need to be compressed?
Since the area of the screen for fitting the profiles remains constant in this case, the profile graphs need to get stretched or compressed in order to fit this area no matter how much distance their path covers on the map. In above cases both 5.18km and 1.13km paths are fitted on the same length axis. Calculations above show how vertical exaggeration is affected by keeping the length of the axis constant and thus changing the scales on the axis for each case.
