tgeompoint_min_dist_at_timestamp() static bool tgeompoint_min_dist_at_timestamp ( const TInstant *  start1, const TInstant *  end1, const TInstant *  start2, const TInstant *  end2, Datum *  value, TimestampTz *  t  ) static Return the value and timestamp at which the two temporal geometric point segments are at the minimum distance. These are the turning points when computing the temporal distance. Parameters [in] start1,end1 Instants defining the first segment [in] start2,end2 Instants defining the second segment [out] value Value [out] t Timestamp Note The PostGIS functions lw_dist2d_seg_seg and lw_dist3d_seg_seg cannot be used since they do not take time into consideration and would return, e.g., that the minimum distance between the two following segments [Point(2 2)@t1, Point(1 1)@t2] and [Point(3 1)@t1, Point(1 1)@t2] is at Point(2 2)@t2 instead of Point(1.5 1.5)@(t1 + (t2 - t1)/2). Precondition The segments are not both constants. Note
