WGS84Coordinate – OPC UA for AutoId Devices – AutoID: OPC UA for AutoId Devices

9.3.16 WGS84Coordinate

This DataType is a structure that defines the georeferenced location of an object on the earth’s surface in latitude, longitude and altitude using the World Geodetic System’s (WGS84) reference frame. Its composition is formally defined in Table 71.

Table 71 – WGS84Coordinate Structure

Name	Type	Description
WGS84Coordinate	Structure	Subtype of Structure defined in OPC 10000-5.
N/S Hemisphere	String	‘N’ or ‘S’ for northern or southern hemisphere
Latitude	Double	Latitude in the unit defined by the GeographicalUnit property of the DeviceLocation Variable of the AutoID Device defined in 6.1.3.12.
E/W Hemisphere	String	‘E’ or ‘W’ for eastern or western hemisphere
Longitude	Double	Longitude in the unit by the GeographicalUnit property of the DeviceLocation Variable of the AutoID Device defined in 6.1.3.12.
Altitude	Double	Altitude in the unit by the GeographicalUnit property of the DeviceLocation Variable of the AutoID Device defined in 6.1.3.12.
Timestamp	UtcTime	Timestamp in UtcTime
DilutionOfPrecision	Double	DOP is a value for the variance of the measurements delivered by the location system. The calculation of the value depends on the underlying system and is vendor specific. Values should be in accordance with the implementations like in GNSS systems.
UsefulPrecisionLatLon	Int32	Values for Latitude and Longitude should be rounded by the client application to the n-th position after the decimal point. It specifies the number of useful digits after the decimal place.
UsefulPrecisionAlt	Int32	Values for Altitude should be rounded by the client application to the n-th position after the decimal point. It specifies the number of useful digits after the decimal place.

Its representation in the AddressSpace is defined in Table 72.
