Distance Measurement Generally, measurements are made horizontally, but on even, often man- made slopes the distance can be measured directly on the slope, but the vertical or zenith angle must be obtained V = Vertical Distance. Equipment grows more and more sophisticated. This is the first book which explains the workings of such equipment already and easily to the average user. It boasts many of the same features – a backlit LCD screen, one-button operation, and durable housing – but it can only measure distances up to 65 feet. A performance test is also a criterion-referenced test if it measures against a set standard or criterion. An Odometer is fitted to vehicles, including bicycles, to measure distances traveled (miles or kilometers). Generally, scientists use these readings to predict when an earthquake will strike.
