Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_PositionConfidenceSet <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
7.53 Data Element: DE_Elevation
Use: Elevation, a value of 2 bytes expressed in decimeters above the reference ellipsoid (typically WSG-
84) with the offset signed value encoding as follows. The value to be sent shall be the value in decimeters
with a constant of 28672 subtracted from it. This offset provides the ability to cover a range from -403.6
meters to +6143.9 meters.
Examples of this encoding are: Given a value of 0 meters, it would be encoded as -28672 (0x7000). Given
a value of +100.0 meters, it would be encoded as -27672 (0x6C18). Given a value of -403.6 meters, it
would be encoded as -32768 (0xFFFF). Given a value of +6143.9 meters, it would be encoded as +32767
(0x7FFF).
ASN.1 Representation:
Elevation ::= INTEGER (-32768..32768)
-- 10 cm LSB with an offset of negative 28672
-- treat as a 2 byte signed value
