1. GRADIENT

5. Gradient
The rate of change in field values between 2 points in a field
field can be elevation, temperature, pressure, etc
(Also known as slope)
Gradient = change in field value
distance

7. EXAMPLE
Determine the gradient of a road where the top has an elevation of 1500 ft and the bottom has an elevation of 800 ft. The length of the road is 50 miles.
Gradient = change in field value distance
1500ft – 800 ft
Gradient =
50 mi
Gradient =
700 ft 50 mi
14 ft/mi =

Elevation: 7,450 to 8,929 feet
Gradient = 8929 – 7450 feet miles
= ft/mi
