### <a name="SegmentSource"></a>SegmentSource
This DF represents the source(s) of the provided segment information.
The corresponding bit shall be set to 1 under the following conditions:
- 0 `navigation` - the information is based on navigation data,
- 1 `learned` - the information is based on recorded, recurring routes,
- 2 `physical` - the information is based on physical prediction (e.g. using sensors).
Values:
***navigation** (0)<br>
***learned** (1)<br>
***physical** (2)<br>
**Categories:** Basic information

This DE indicates the horizontal position confidence value which represents the estimated absolute position accuracy, in one of the axis direction as defined in a shape of ellipse with a
This DE indicates the actual status of the front wipers of the vehicle.
The value shall be set to:
- 0 `unavailable` - to indicate that the information is unavailable,
- 1 `off` - to indicate that the wipers are switched off,
- 2 `intermittent` - to indicate that the wipers are moving intermittently,
- 3 `low` - to indicate that the wipers are moving at low speed,
- 4 `high` - to indicate that the wipers are moving at high speed,
- values 5 to 7 - are reserved for future usage.
Values:
***unavailable** (0)<br>

This DE represents the World Manufacturer Identifier (WMI). The values are assigned according to ISO 3779 [[6]](#references).
This DF represents the top-level DF to represent a lane position. A lane position is a transversal position on the carriageway at a specific longitudinal position, in resolution of lanes of the carriageway.
The data frame PolygonalLine shall contain the definition of a polygonal line (also known as polygonal chain) w.r.t. an externally defined reference position.
The following options are available:
* _deltaPositions_ of type [**DeltaPositions**](#DeltaPositions) <br>
an ordered sequence of delta geographical positions with respect to the previous position, with latitude and longitude,
with the first instance referring to the reference position and with the order implicitly defining a direction associated with the polygonal line.
* _deltaPositionsWithAltitude_ of type [**DeltaReferencePositions**](#DeltaReferencePositions) <br>
an ordered sequence of delta geographical positions with respect to the previous position, with latitude, longitude and altitude,
with the first instance referring to the reference position and with the order implicitly defining a direction associated with the polygonal line.
* _absolutePositions_ of type [**GeoPositionsWAltitude**](#GeoPositionsWAltitude) <br>
a sequence of absolute geographical positions, with latitude and longitude.
* _absolutePositionsWithAltitude_ of type [**GeoPositionsWoAltitude**](#GeoPositionsWoAltitude) <br>
a sequence of absolute geographical positions, with latitude, longitude and altitude.
