Vertical Exaggeration Formula:
From: | To: |
Vertical Exaggeration (VE) is the ratio between the horizontal scale and vertical scale in a topographic profile or cross-section. It's used to emphasize subtle changes in elevation that might otherwise be hard to see.
The calculator uses the Vertical Exaggeration equation:
Where:
Explanation: When VE > 1, vertical features appear exaggerated compared to their horizontal dimensions. When VE < 1, vertical features appear compressed.
Details: Vertical exaggeration is crucial in geological cross-sections, topographic profiles, and seismic interpretation to make subtle features visible while maintaining accurate spatial relationships.
Tips: Enter both horizontal and vertical scales as dimensionless ratios (e.g., 1:24000 would be entered as 0.00004167). Both values must be greater than zero.
Q1: What's a typical vertical exaggeration value?
A: Common values range from 2x to 10x in geological cross-sections, depending on the terrain and purpose.
Q2: How does vertical exaggeration affect interpretation?
A: High VE makes gentle slopes appear steeper, which can distort perception of true landforms but reveals subtle features.
Q3: When should I avoid vertical exaggeration?
A: When precise slope measurements are needed or when comparing features with different exaggerations.
Q4: How do I convert map scales to ratios?
A: A scale of 1:24000 becomes 1/24000 = 0.00004167. For feet: 1"=2000' becomes 1/2000 = 0.0005.
Q5: Can vertical exaggeration be less than 1?
A: Yes, VE < 1 means vertical features are compressed relative to horizontal (rarely used in practice).
