Calculation and interpretation of vertical exaggeration and gradient

Answer Text:
Calculation and Interpretation of Vertical Exaggeration and Gradient Vertical Exaggeration
Number of times that the vertical scale is larger than horizontal scale V.E. =Denominator of H.S. /D. of V.S. (cross section scale. e.g. V.S. =1:20M
H. S=1:50000
V.E.=50000/20×100 (To convert into cm) =25
-The vertical height has been exaggerated 25 times compared to the horizontal distance
Invisibility
-Ability of one place to be seen from another
-Draw cross section
-Join points A-B using visibility line
-If the visibility line is above the cross section, the two points are indivisible. If below they are not indivisible.
