6.2.3 Spatial Relationship Operators
The definitions of named spatial relationships between geometric objects follow the definitions in [ISO CD 19107]. They are based on the Dimensionally Extended nine-
Intersection Model DE-9IM. Because the DE-9IM based specification of each named relationship is very formal and cannot be expressed in simple English for each case, the
following verb concepts only refer to the source of the definition, but do not provide the definition itself. In addition to the named operators, the “relates” operator has been
included to support specific use cases. Where appropriate for use in SBVR rules, suggestions for synonyms have been added.

geometry is‐within‐distance

to geometry
Note: This is equal to testing that a a buffer created around the first geometry with given measure as distance and b the second
geometry intersect.

geometry is‐beyond
measure to
geometry
Note: This is equal to testing that a a buffer created around the first geometry with given measure as distance and b the second
geometry are disjoint.
