Vertical exaggeration-how?

Question

So 1'=2500 feet.
I measured point x to y and that = 8750 feet (if this is calculated by measuring inches from these 2 points)...

i measured the profile (the line graph provided) and that measures 2,813 feet.
so i divided.
the example in my book reads a 10x exaggeration.
how is this possible if i am dividing horizontal over vertical?
what am i doing wrong?

Answer 1

Basically, in a line drawing (an X-Y graph), vertical exageration means that the scale of the drawing is one value for the X direction and another value in the Y direction. If 1 inch = 2500 feet in the X direction, the value would be 1 inch = 250 feet in the Y direction for a graph with a 10X vertical exageration. A vertical (Y value) distance in the real world will be 10 times the size of that same real world distance in the X (horizontal direction) when graphed.



2500 feet in the horizontal is shown as one inch, but 2500 feet in the vertical is shown as 10 inches.

Answer 2

Vertical exaggeration in cartography refers to a cross section (or profile) where the Y axis is at a more detailed scale (smaller number) than the X axis, so as to provide more detail in the section.



For your 10x exaggeration, for example, the horizontal scale could be 1:10,000 and the vertical scale could be 1:1000. H/V or 10,000/1000 = 10x exaggeration.



EDIT - you said your profile was 2813 feet, but you didn't say if that was the X axis or the Y axis. With 10x vertical exaggeration, the other axis must be either 218 feet or 28,130 feet.

topographic maps are the maps that have the bumps on them, or they are 3-D images of land. Topography means arrangement of natural and artificial physical features of an area basically, they are the physical maps that shows landforms like mountains by circles that show elevations and depressions, etc
