The 1:625k DiGMap data covering the whole of the United Kingdom is available in this OGC WFS service for all uses - including commercial use subject to the conditions in the Access Constraints section. It is being served as a contribution to the OneGeology initiative(www.onegeology.org). The data is available in INSPIRE geology theme schema v3.0, GeoSciML v4.1 and GeoSciML v3.2 formats. INSPIRE vocabulary values are used in most cases where applicable. Some other properties use IUGS-CGI vocabulary values. For information about more of the British Geological Survey's maps that are available digitally please visit http://www.bgs.ac.uk/products/digitalmaps/digmapgb.html
GeoSciML v3.2 Mapped Feature (gsml:MappedFeature)
A MappedFeature is part of a geological interpretation. It provides a link between a notional feature (description package) and one spatial representation of it, or part of it. (Exposures, Surface Traces and Intercepts, etc) * the specific bounded occurrence, such as an outcrop or map polygon * the Mapped Feature carries a geometry or shape - the association with a Geologic Feature (legend item) provides specification of all the other descriptors - the association with a Sampling Feature provides the context and dimensionality A Mapped Feature is always associated with some sampling feature - e.g. a mapping surface, a section, a Borehole (see BoreHolesAndObservation) etc. As noted on the diagram, if the associated sampling feature is a Borehole, then the shape associated with the MappedFeature will usually be either a point or an interval. This reconciles the 2-D ("map", section) and 1-D (borehole, traverse) viewpoints in a common abstraction.

GeoSciML v4.1 Geologic Unit (gsmlb:GeologicUnit)
Operationally, the GeologicUnit element is a container used to associate geologic properties with some mapped occurrence (through GeologicFeature.occurrence -> MappedFeature link), or with a geologic unit ControlledConcept in a vocabulary (through the GeologicUnit.classifier ->ControlledConcept link). Conceptually, may represent a body of material in the Earth whose complete and precise extent is inferred to exist (NADM GeologicUnit, Stratigraphic unit in sense of NACSN or International Stratigraphic Code), or a classifier used to characterize parts of the Earth (e.g. lithologic map unit like 'granitic rock' or 'alluvial deposit', surficial units like 'till' or 'old alluvium'). Spatial properties are only available through association with a MappedFeature. Includes both formal units (i.e. formally adopted and named in the official lexicon) and informal units (i.e. named but not promoted to the lexicon) and unnamed units (i.e. recognisable and described and delineable in the field but not otherwise formalised).
GeologicUnitView (gsmlp:GeologicUnitView)
INSPIRE Schema v3.0 Geologic Unit (ge:GeologicUnit)
-- Definition -- A volume of rock with distinct characteristics. -- Description -- Includes both formal units (i.e. formally adopted and named in an official lexicon) and informal units (i.e. named but not promoted to the lexicon) and unnamed units (i.e. recognisable and described and delineable in the field but not otherwise formalised). Spatial properties are only available through association with a MappedFeature.
GeoSciML v3.2 Geologic Unit (gsmlgu:GeologicUnit)
Operationally, the GeologicUnit element is a container used to associate geologic properties with some mapped occurrence (through GeologicFeature.occurrence -> MappedFeature link), or with a geologic unit ControlledConcept in a vocabulary (through the GeologicUnit.classifier ->ControlledConcept link).

GeoSciML v4.1 Shear Displacement Structure (gsmlb:ShearDisplacementStructure)
A shear displacement structure includes all brittle to ductile style structures along which displacement has occurred, from a simple, single 'planar' brittle or ductile surface to a fault system comprised of 10's of strands of both brittle and ductile nature. This structure may have some significant thickness (a deformation zone) and have an associated body of deformed rock that may be considered a DeformationUnit

INSPIRE Schema v3.0 Mapped Feature (ge:MappedFeature)
-- Definition -- A spatial representation of a GeologicFeature. -- Description -- A MappedFeature is part of a geological interpretation. It provides a link between a notional feature (description package) and one spatial representation of it, or part of it (exposures, surface traces and intercepts, etc) which forms the specific bounded occurrence, such as an outcrop or map polygon.
