6.4 Zones
A zone defines an area in which a location is computed. A zone translates local locations related to the area of the zone to global geographic locations. A zone is defined by the ZoneType ObjectType (see 7.1). In Figure 8, the ObjectType is shown.

The relation between zones and the global position and global location is shown in an example in Figure 9. The global position Variable X:MyPosition references with its SourceId Variable the X:Zone123, and the global location Variable X:MyLocation with the SourceId Variable of its position the X:Zone234. The GlobalLocations Object defined in 10.1 is the standardized entry point to zones provided by a Server.
