6.6. Functions and Operators for Temporal Network Points

All functions for temporal types described in Chapter 5 can be applied for temporal network point types. Therefore, in the signatures of the functions, the notation base also represents an npoint and the notations ttype, tpoint, and tgeompoint also represent a tnpoint. Furthermore, the functions that have an argument of type geometry accept in addition an argument of type npoint. To avoid redundancy, we only present next some examples of these functions and operators for temporal network points.
