8.3 Geometrical Information Stored as a Property

Sometimes it is necessary to store geometrical information about the elements of a representation, for example, for former locations, height, distance, etc. Specific examples include descriptions such as a depth of the oil-water contact, or throw of a fault from the footwall to the hanging wall.

To use property capabilities for this type of data requires a coordinate system, which is why an optional link between properties and a local coordinate system is available in the data model.

When spatial locations need to be stored, a specific kind of property is used: points property, which is based on an array of points instead of an array of values.
