Borehole - Spatial object type

Definition: A borehole is the generalized term for any narrow shaft drilled in the ground.

INSPIRE Data Theme: Geology - [INSPIRE Data Theme Geology]

INSPIRE Application schema: Geology - [INSPIRE Application schema Geology]


Attributes

Definition: The purpose for which the borehole was drilled.

Description: EXAMPLE: site investigation, mineral exploration, hydrocarbon exploration, water resources.

Multiplicity: 1...*

Stereotypes: voidable

Valuetype: BoreholePurposeValue

Definition: External object identifier of the spatial object.

Multiplicity: 1

Valuetype: Identifier

Multiplicity: 1

Stereotypes: voidable

Valuetype: GM_Curve

Definition: The distance along a borehole.

Description: This will be determined by the data provider (ie, "length" can have different sources, like drillers measurement, loggers measurement, survey).

Multiplicity: 1

Stereotypes: voidable

Valuetype: Quantity

Definition: The vertical height above datum of the borehole collar.

Description: This is a compromise approach to supply elevation explictly for location; this is to allow for software that ca
ot process 3-D GM_Point. Use null if elevation is unknown. Direct position shall have a dimension of 1, and CRS will be a "vertical" CRS (e.g. EPSG CRSs in the range 5600-5799).

Multiplicity: 1

Stereotypes: voidable

Valuetype: DirectPosition

Definition: The location of the borehole collar.

Multiplicity: 1

Valuetype: GM_Point


Associated objects - Mandatory

Definition: A special kind of mapped feature whose shape is a 1-D interval and which uses the SRS of the containing borehole.

Multiplicity: 1..*

Name of the association: log Element

Association definition: 1-D MappedFeature instances that are logged (interpreted) intervals within a borehole.

INSPIRE Data Theme: Geology - [INSPIRE Data Theme Geology]

INSPIRE Application schema: Geology - [INSPIRE Application schema Geology]

Subtype of: MappedFeature


Attributes

Definition: The geometry of the mapped feature.

Multiplicity: 1

Valuetype: GM_Object

Definition: The surface on which the mapped feature is projected.

Description: EXAMPLE: Topographic surface, Bedrock surface, Base of Permian

Multiplicity: 1

Valuetype: MappingFrameValue


Associated objects - Mandatory

Definition: A conceptual geological feature that is hypothesized to exist coherently in the world.

Description: This corresponds with a "legend item" from a traditional geologic map. While the bounding coordinates of a Geologic Feature may be described, its shape is not.The implemented Geologic Feature instance acts as the "description package"

Multiplicity: 1

Name of the association: specification

Association definition: A description association that links a mapped feature to a notional geologic feature.

Supertype of: GeologicStructure GeologicUnit GeomorphologicFeature EarthResource


Attributes

Definition: External object identifier of the spatial object.

Multiplicity: 1

Valuetype: Identifier

Definition: The name of the geologic feature.

Description: EXAMPLE: a lithostratigraphic unit, mineral occurrence, or major fault. Not all GeologicFeatures will have names, for example minor faults.

Multiplicity: 1

Stereotypes: voidable

Valuetype: CharacterString
