- An EarthMaterial that belongs to the class of chemical compounds having a reduced carbon basis (as distinct from carbonates), and derived from living organisms. Includes high-carbon EarthMaterials such as bitumen, peat, and coal.
This class is an empty placeholder for extension at a later date, or by other domain models
- Organism
- Broad class to represent any living or once living thing. This is the connection to taxonomy/biology for fossils.
- OriginPosition
- A Borehole OriginPosition is a feature corresponding to the start point of a borehole log. This may, but not necessarily, correspond to the borehole collar location (eg, kelly bush).
If a text descripiton of the location is available, it should be placed in the gml:description for that feature. If no GM_Point is available, an OGC nil value should be used.
Implementers delivering 3-D origin locations should provide an elevation to improve interoperability.
In situations where the origin position changes over the life of the borehole (eg, due to subsidence or destruction of the original collar), the origin position should be updated to the new location.
