The angle from the horizontal plane. For lines or directions, 0 means flat across the horizontal plane, a positive value means the angle directs up, and negative angle directs down. For inclines, 0 means a perfectly flat surface, and the higher the angle the steeper the surface.
| Value | Cardinal direction |
|---|---|
| 0° | Flat on the horizontal plane |
| 90° | Straight up, perpendicular to the horizontal plane |
| -90° | Straight down, perpendicular to the horizontal plane |
