The TCS GIM GeologicFeatureIndex is an implementation of the GeologicFeatureIndex and contains discovery information for the pan-European surface geology at 1:1,000,000 scale. It is a transnational map provided by EGDI and harvested from INSPIRE-compliant national web feature services on GeologicUnit. There are two services made available to the users:

identifier [CharacterString]:
Globally unique identifier:Primitive::CharacterString shall uniquely identifies a tuple within the dataset. Identifiers shall be formatted as URI according to RFC 3986. This URI could be used to access more detailed, such as a GeoSciML Basic, representation of the feature. The identifier should have the same value as the corresponding GeoSciML MappedFeature identifier, if available.

geologicUnitType [GeologicUnitTypeCode]:
If present, the property geologicUnitType (Primitive::CharacterString) contains the type of GeologicUnit (as defined in GeoSciML).

rank [GeologicUnitRankCode]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, the property rank:Primitive::CharacterString contain the rank of GeologicUnit (as defined by ISC. e.g., group, formation, member).

lithology [LithologyCode]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, lithology contains a human readable description as Primitive::CharacterString of the GeologicUnit’s lithology, possibly formatted with formal syntax. The description can be language-dependent.
targetCodeList: http://inspire.ec.europa.eu/codelist/LithologyValue

geologicHistory [CharacterString]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, contains a human readable description in Primitive::CharacterString, possibly formatted with formal syntax, of the age of the GeologicUnit (where age is a sequence of events and may include process and environment information). To report an identifier from a controlled vocabulary, representativeAge_uri, representativeOlderAge_uri, representativeYoungerAge_uri shall be used.

numericOlderAge [Measure]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, the property numericOlderAge age is a numerical representation (Primitive::Number) of the unit’s older age in million years (Ma).

numericYoungerAge [Measure]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, the property numericYoungerAge is a numerical representation (Primitive::Number) of the unit’s younger age in million years (Ma).

observationMethod [CharacterString]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, the property observationMethod:Primitive::CharacterString is a metadata snippet indicating how the spatial extent of the feature was determined. ObservationMethod is a convenience property that provides a simple approach to observation metadata when data are reported using a feature view (as opposed to observation view).

positionalAccuracy [CharacterString]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
An estimate of the accuracy of the location of the borehole collar location.

source [CharacterString]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, the property source:Primitive::CharacterString is human readable text describing feature-specific details and citations to source materials, and if available provides URLs to reference material and publications describing the geologic feature. This could be a short text synopsis of key information that would also be in the metadata record referenced by metadata_uri.
At this point the property gives information on a feature data provider (Country and organization. Options are: AT_GBA, BE-GSB, CZ-CGS, DE-BGR, DK-GEUS, ES-IGME, FI-GTK, FR-BRGM, GB-BGS, GR-IGME, HU-MFGI, IR-GSI, IS-NI, IT-ISPRA, LU-SGL, MT, NL-TNO, NO-NGU, PL-PGI, PT-LNEG, SE-SGU, SI-GeoZS, SK_SGUDS)

representativeAge_uri [RepresentativeAgeCode]:
The property representativeAge_uri:Primitive::CharacterString shall contain a URI referring to a controlled concept specifying the most representative stratigraphic age interval for the GeologicUnit. This will be defined entirely at the discretion of the data provider and may be a single event selected from the geologic feature’s geological history or a value summarising the all or part of the feature’s history.
targetCodeList: http://inspire.ec.europa.eu/codelist/GeochronologicEraValue

representativeOlderAge_uri [RepresentativeOlderAgeCode]:
The property representativeOlderAge_uri:Primitive::CharacterString shall contain a URI referring to a controlled concept specifying the most representative older value in a range of stratigraphic age intervals for the GeologicUnit. This will be defined entirely at the discretion of the data provider and may be a single event selected from the geologic feature’s geological history or a value summarising the all or part of the feature’s history.

representativeYoungerAge_uri [RepresentativeYoungerAgeCode]:
The property representativeYoungerAge_uri:Primitive::CharacterString shall contain a URI referring to a controlled concept specifying the most representative younger value in a range of stratigraphic age intervals for the GeologicUnit. This will be defined entirely at the discretion of the data provider and may be a single event selected from the geologic feature’s geological history or a value summarising the all or part of the feature’s history.

specification_uri [CharacterString]:
If present, the property specification_uri:Primitive::CharacterString shall contain a URI referring the GeoSciML GeologicUnit feature that describes the instance in detail.

metadata_uri [CharacterString]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, the property metadata_uri:Primitive::CharacterString contains a URI referring to a metadata record describing the provenance of data.

genericSymbolizer [CharacterString]:
Multiplicity: ( [0..1], Allow duplicates: 0, Is ordered: False )
If present, the property genericSymbolizer:CharacterString contains an identifier for a symbol from standard (locally or community defined) symbolization scheme for portrayal.

shape [GM_Object]:
The property shape:GEO::GM_Object contains a geometry defining the extent of the feature of interest.
