First, we need to calculate the vertical distance between spot height 421 and spot height 444.
Vertical distance = 444 - 421 = 23

Next, we can calculate the gradient using the formula:
Gradient = vertical distance / horizontal distance
Gradient = 23 / 3000
Gradient = 0.00767

Therefore, the gradient between spot height 421 and spot height 444 is 0.00767.
