Exists if the subject SpatialObject is spatially disjoint from the object SpatialObject. DE-9IM: FF*FF****
disjoint
Exists if the subject SpatialObject is not spatially disjoint from the object SpatialObject. DE-9IM: T******** ^ *T******* ^ ***T***** ^ ****T****
intersects
Exists if the subject SpatialObject is spatially inside the object SpatialObject. DE-9IM: TFFTFFTTT
non-tangential proper part
touches
Exists if the subject SpatialObject spatially touches the object SpatialObject. DE-9IM: FT******* ^ F**T***** ^ F***T****
inside
Exists if the subject SpatialObject is spatially inside the object SpatialObject. DE-9IM: TFF*FFT**
Feature
This class represents the top-level feature type. This class is equivalent to GFI_Feature defined in ISO 19156:2011, and it is superclass of all feature types.
contains
Exists if the subject SpatialObject spatially contains the object SpatialObject. DE-9IM: T*TFF*FF*
Spatial Relations Ontology
An ontology describing basic spatial relations.
isEmpty
(true) if this geometric object is the empty Geometry. If true, then this geometric object represents the empty point set for the coordinate space.
crosses
Exists if the subject SpatialObject spatially crosses the object SpatialObject. DE-9IM: T*T******
dimension
The topological dimension of this geometric object, which must be less than or equal to the coordinate dimension. In non-homogeneous collections, this will return the largest topological dimension of the contained objects.
Exists if the subject SpatialObject is spatially disjoint from the object SpatialObject. DE-9IM: FFTFFTTTT
disconnected
A spatial representation for a given feature.
hasGeometry
Exists if the subject SpatialObject spatially contains the object SpatialObject. DE-9IM: T*****FF*
The number of measurements or axes needed to describe the position of this geometry in a coordinate system.
coordinateDimension
The WKT serialization of a geometry
asWKT
Exists if the subject SpatialObject spatially meets the object SpatialObject. DE-9IM: FT******* ^ F**T***** ^ F***T****

OGC GeoSPARQL – A Geographic Query Language for RDF Data OGC 11-052r5
An RDF/OWL vocabulary for representing spatial information
Connects a geometry object with its text-based serialization.
has serialization
Exists if the subject SpatialObject spatially overlaps the object SpatialObject. DE-9IM: T*T***T**
overlaps
The default geometry to be used in spatial calculations. It is Usually the most detailed geometry.
defaultGeometry
The number of measurements or axes needed to describe the spatial position of this geometry in a coordinate system.

A Well-known Text serialization of a geometry object.
Well-known Text Literal
Exists if the subject SpatialObject spatially covers the object SpatialObject. DE-9IM: T*TFT*FF*
covers
Exists if the subject SpatialObject spatially overlaps the object SpatialObject. DE-9IM: TTTTTTTTT
partially overlapping
(true) if this geometric object has no anomalous geometric points, such as self intersection or self tangency.
isSimple
Exists if the subject SpatialObject is spatially covered by the object SpatialObject. DE-9IM: TFFTTFTTT
tangential proper part
The class represents the top-level geometry type. This class is equivalent to the UML class GM_Object defined in ISO 19107, and it is superclass of all geometry types.
Geometry
Exists if the subject SpatialObject spatially meets the object SpatialObject. DE-9IM: FFTFTTTTT
externally connected
The class spatial-object represents everything that can have a spatial representation. It is superclass of feature and geometry.
