I was wondering how do they measure coasters according to height?
There are two ways to measure height, one way is the structure's highest point above ground (most define this as the coaster's height). Another way is the greatest continuous drop on the roller coaster. Some roller coasters are on slopes and use the natural topography of the land to achieve a drop greater than the ride's structural height.
Was this the answer you wanted or did you want how they actually perform the measurements?
Well To answer the perform part. I believe the height of a coaster can be performed several different ways.
One way for an accurate measure would be to use Mathematics specifically Trigonometry. Sin/cos/tan laws.
