Notation

We presented in the section called “Notation” and in the section called “Notation” the notation used for defining the signature of the functions and operators for temporal types. We extend next this notations for temporal spatial types.

  • tspatial represents a temporal spatial type, such as, tgeometry, tgeompoint, tpose, or tnpoint,

  • tgeo represents a temporal geometry/geography type, that is, tgeometry, tgeography, tgeompoint, or tgeogpoint,

  • tgeom represents a temporal geometry type that is, tgeometry or tgeompoint,

  • tpoint represents a temporal point type, that is, tgeompoint or tgeogpoint,

  • spatial represents a spatial base type, such as, geometry, geography, pose, or npoint,

  • geo represents the types geometry or geography,

  • geompoint represents the type geometry restricted to a point.

  • point represents the types geometry or geography restricted to a point.

  • lines represents the types geometry or geography restricted to a (multi)line.

In the following, we specify with the symbol that the function supports 3D geometries and with the symbol that the function supports geographies.
