Spatial representation information (includes grid and vector representation). The following is adapted from OpenGIS® Metadata (Topic 11) specification.
This package contains information concerning the mechanisms used to represent spatial information in a dataset. The spatial representation entity is optional and can be specified as grid spatial representation and vector spatial representation. Each of the specified entities contains mandatory and optional metadata elements. When further description is necessary, vector spatial representation may be specified as georectified. and/or georeferenceable entity.

Interface Summary Interface Description DimensionAxis properties. GeometricObjectsNumber of objects, listed by geometric object type, used in the dataset. GeorectifiedGrid whose cells are regularly spaced in a geographic (i.e., lat / long) or map coordinate system defined in the Spatial Referencing System (SRS) so that any cell in the grid can be geolocated given its grid coordinate and the grid origin, cell spacing, and orientation indication of whether or not geographic. GeoreferenceableGrid with cells irregularly spaced in any given geographic/map projection coordinate system, whose individual cells can be geolocated using geolocation information supplied with the data but cannot be geolocated from the grid properties alone. GridSpatialRepresentationBasic information required to uniquely identify a resource or resources. SpatialRepresentationDigital mechanism used to represent spatial information. VectorSpatialRepresentationInformation about the vector spatial objects in the dataset.
Class Summary Class Description CellGeometryCode indicating whether grid data is point or area. DimensionNameTypeName of the dimension. GeometricObjectTypeName of point and vector spatial objects used to locate zero-, one-, and twodimensional spatial locations in the dataset. PixelOrientationPoint in a pixel corresponding to the Earth location of the pixel. SpatialRepresentationTypeMethod used to represent geographic information in the dataset. TopologyLevelDegree of complexity of the spatial relationships.
