In OpenGround, the Orientation and Inclination group (OrientationAndInclination) is used to define the direction and angle of inclined (non-vertical) boreholes.
Note: For vertical boreholes, this information is typically not required.
Orientation
- Orientation is the bearing or direction of the borehole.
- Orientation is measured in degrees clockwise from North.
- Use positive values as standard (negative values are allowed but not typically used).
Examples:
| Direction | Orientation |
| North | 0° |
| East | 90° |
| South | 180° |
Inclination
- Inclination is the plunge or angle from horizontal of the borehole.
- Inclination is measured in degrees from horizontal, positive downward.
- While values outside the -90° to 90° range are supported, they are not typically used.
Examples:
| Borehole Angle | Inclination |
| Vertical down | 90° |
| Vertical up | -90° |
| Horizontal | 0° |
| 30° below horizontal | 30° |
Important: Inclination in OpenGround is stored the opposite of gINT. If importing data from gINT, reverse the inclination sign.
Multiple Orientation/Inclination Entries
OpenGround supports multiple entries for Orientation and Inclination at different depths to represent deviated boreholes.
Note: Some features in OpenGround only support a single orientation/inclination per borehole (see links below).
Features That Support Inclined Boreholes
Several OpenGround tools and functions are designed to work with inclined borehole data:
Inclined boreholes are displayed accurately in Quick Sections.
Automatically adjust based on inclination when configured to show elevations.
Some Run Time Functions take inclination into account when calculating elevations, such as:
-
- [Paging.CurrentSheetStartElevation]
- [Paging.CurrentSheetEndElevation]
