Concept Definitions

crosses

IRI http://www.opengis.net/def/function/geosparql/rcc9cr
Definition A query function that returns true if the first geometry argument spatially crosses the second geometry argument. DE-9IM: T*TFFTT** v TFT*F*TT* v TFTFFFTFT v TTTFFFTTT v TFTTFTTFT
Is Defined By This vocabulary
Source http://www.opengis.net/doc/geosparql/1.1

disconnected

IRI http://www.opengis.net/def/function/geosparql/rcc9dc
Definition A query function that returns true if the input geometries are disjoint. DE-9IM: FF*FF****
Is Defined By This vocabulary

equals

IRI http://www.opengis.net/def/function/geosparql/rcc9eq
Definition A query function that returns true if the input geometries are equal. DE-9IM: TFFF*FFFT

externally connected

IRI http://www.opengis.net/def/function/geosparql/rcc9ec

Is Defined By This vocabulary
Source http://www.opengis.net/doc/geosparql/Next

non-tangential proper part inverse

IRI http://www.opengis.net/def/function/geosparql/rcc9ntppi
