This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
7.39 Data Element: DE_Short Latitude
Use: A shorted value of latitude representing the lower 16 bits of a 32 bit value. Taken together with the Long
Latitude data element, a complete value of latitude can be obtained which is identical in value domain to the std
ITS latitude with an LSB of one 1/8th micro degree. The latitude is the position of the center of the vehicle,
expressed in 1/8th micro degrees and based on the WGS-84 coordinate system, represented in a 4 byte value.
ASN.1 Representation:
ShortLatitude ::= INTEGER (0..65535) -- lower 16 bits of a 32 bit Latitude
XML Representation:
<xs:simpleType name="ShortLatitude" >
<xs:annotation>
<xs:documentation>
lower 16 bits of a 32 bit Latitude
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:unsignedShort"/>
</xs:simpleType>
In addition, this item may be used by data structures in other ITS standards.
7.40 Data Element: DE_Short Longitude
Use: A shorted value of longitude representing the lower 16 bits of a 32 bit value. Taken together with the Long
Longitude data element, a complete value of longitude can be obtained which is identical in value domain to the std
ITS longitude with an LSB of one 1/8th micro degree. The longitude is the position of the center of the vehicle,
expressed in 1/8th micro degrees and based on the WGS-84 coordinate system, represented in a 4 byte value.
ASN.1 Representation:
ShortLongitude ::= INTEGER (0..65535) -- lower 16 bits of a 32 bit Longitude
XML Representation:
<xs:simpleType name="ShortLongitude" >
<xs:annotation>
<xs:documentation>
lower 16 bits of a 32 bit Longitude
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:unsignedShort"/>
</xs:simpleType>
In addition, this item may be used by data structures in other ITS standards.
7.41 Data Element: DE_ShortElevation RETIRE THIS ONE
Use: Short Elevation, is a shortened value of Elevation, representing the least significant 8 bits of DE_Elevation.
ASN.1 Representation:
ShortElevation ::= INTEGER (0..255) -- 10 cm LSB
XML Representation:
<xs:simpleType name="ShortElevation" >
<xs:annotation>
<xs:documentation>
10 cm LSB
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:unsignedByte"/>
