- Click the Input surface dropdown arrow and click the surface for which you want to calculate the slope.
- Choose the Output measurement units.
- Specify a z-factor if your z units are in a different unit of measure than your x,y units.
How do you calculate the slope of a lot?
Slope can be calculated as a percentage which is calculated in much the same way as the gradient. Convert the rise and run to the same units and then divide the rise by the run. Multiply this number by 100 and you have the percentage slope. For instance, 3″ rise divided by 36″ run = .
