Fence
Options that describe how a FenceGeotrigger uses accuracy information from a GeotriggerFeed. This enumeration defines options for using accuracy information from a GeotriggerFeed to provide the Geometry for checking a Geotrigger condition. In particular, you can choose how to use the Location.horizontalAccuracy property to reflect the uncertainty around a fixed Location.position. Due to various factors, GPS positions may be inaccurate, with Location.horizontalAccuracy representing a radius that defines the area containing the actual location. Spurious notifications may occur when the Location.position is inaccurate and is incorrectly reported as inside or outside of a fence. You can use the Location.horizontalAccuracy to account for that uncertainty.
These values are used in conjunction with FenceGeotrigger.enterExitSpatialRelationship to affect when notifications are sent.

Types
The reported Geometry from a GeotriggerFeed is used. For a LocationGeotriggerFeed the point geometry from the Location.position property is used.
The reported Geometry from a GeotriggerFeed is used in conjunction with accuracy information. For a LocationGeotriggerFeed the point geometry from the Location.position property is buffered by the Location.horizontalAccuracy to produce a polygon geometry.
