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.

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.
