Used by: This entry is used directly by one other data structure in this standard, a MSG called
MSG_NMEA_Corrections <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
7.57 Data Element: DE_NMEA_MsgType
Use: The NMEA-MsgType provides the--- value defined in the NMEAstandards for each message. In this
standard this -- tbd.
ASN.1 Representation:
NMEA-MsgType ::= INTEGER (0..65535)
XML Representation:
<xs:restriction base="xs:unsignedShort"/>

Used by: This entry is used directly by one other data structure in this standard, a MSG called
MSG_NMEA_Corrections <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
7.58 Data Element: DE_ObstacleDirection
Use: As a companion data element to Obstacle Distance, this data element draws from the output of a
forward sensing system to report the obstacle direction from the vehicle detecting and reporting the
obstacle. The data is expressed in degrees as azimuth relative to forward direction of vehicle.
ASN.1 Representation:
ObstacleDirection ::= Heading -- Use the header DE for this unless it proves different.
XML Representation:
<xs:simpleType name="ObstacleDirection" >
<xs:annotation>
<xs:documentation>
Use the header DE for this unless it proves different.

Used by: This entry is directly used by the following 2 other data structures in this standard (record type,
descriptive name, ASN.1, and XML name (if present) of each):
DF
<XML>, and
DF
In addition, this item may be used by data structures in other ITS standards.
7.59 Data Element: DE_ObstacleDistance
Use: This data element draws from the output of a forward sensing system to report the presence of an
obstacle and its measured distance from the vehicle detecting and reporting the obstacle. This information
can be used by road authorities to investigate and remove the obstacle, as well as by other vehicles in
advising drivers or on-board systems of the obstacle location. Distance is expressed in meters.
ASN.1 Representation:
ObstacleDistance ::= INTEGER (0..999) -- units of meters
