They have many names, such as contour lines, level curves, and isoheights. Levees can help reduce erosion, reduce runoff, and promote water capture.</span>

- <span style="font-size: 18px;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="color: rgb(0, 0, 0); font-weight: 300;">Levees can be added at set intervals.</span></span></span>
- <span style="font-size: 18px;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="color: rgb(0, 0, 0); font-weight: 300;">Levees can be smoothed.</span></span></span>
- <span style="font-size: 18px;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="color: rgb(0, 0, 0); font-weight: 300;">Levees can be selectively deleted.</span></span></span>
- <span style="font-size: 18px;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="color: rgb(0, 0, 0); font-weight: 300;">Levees can be applied selectively to field regions.</span></span></span>
- <span style="font-size: 18px;"><span style="font-family: Arial,Helvetica,sans-serif;"><span dir="ltr" style="color: rgb(0, 0, 0); font-weight: 300;">Levees can be exported as guidance curves for use with John Deere AutoTrac</span></span></span><span style="font-size: 18px; font-family: Arial, Helvetica, sans-serif; color: rgb(0, 0, 0); font-weight: 300;">™.</span>

<span style="font-size: 18px; font-family: Arial, Helvetica, sans-serif; color: rgb(0, 0, 0); font-weight: 300;">Levees can be used to split regions. When doing so, we recommend splitting with a small number of levees. Splitting regions at levees consumes the levees in the process. To create more levees after this, it's recommended to change the elevation or vertical interval to get best results.</span>
