This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
7.86 Data Element: DE_Long Latitude (REMOVE)
Use: A shortened value of latitude representing the upper 16 bits of a 32 bit value. Taken together with
the Short 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:
LongLatitude ::= INTEGER (0..65535) -- upper 16 bits of a 32 bit lat-long
XML Representation:
<xs:simpleType name="LongLatitude" >
<xs:annotation>
<xs:documentation>
upper 16 bits of a 32 bit lat-long
</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.
7.87 Data Element: DE_Longitude
Use: The geographic longitude of a node, expressed in 1/8th integer microdegrees, as a 32 bit value and
with reference to the horizontal datum specified by horizontalDatum.
ASN.1 Representation:
Longitude ::= INTEGER (-1440000000..1440000000)
-- in LSB = 1/8 micro degree
-- Providing a range of plus-minus 180 degrees
XML Representation:
<xs:simpleType name="Longitude" >
<xs:annotation>
<xs:documentation>
in LSB = 1/8 micro degree
Providing a range of plus-minus 180 degrees
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:int">
<xs:minInclusive value="-1440000000"/>
<xs:maxInclusive value="1440000000"/>
</xs:restriction>
</xs:simpleType>
