Used By: This entry is used directly by one other data structure in this standard, a DF called DF_NodeList
Remarks: Note that while lat and long and elevation values are provided in the reference point with
respect to the common geiod, these offsets are given in absolute distance (units of 1.0 cm) of offset.
When a value for zOffsret or for LaneWidth is given, that value persists until changed again for additional
nodes in the list.
6.30 Data Frame: DF_Position2D
Use: A collection of the two 4 byte lat-long information elements used to build a complete 2D position set.
No elevation data is sent in this 8 bytes data frame.
ASN.1 Representation:
Position2D ::= SEQUENCE {
lat Latitude, -- in 1/8th micro degrees
long Longitude -- in 1/8th micro degrees
}
