Re: Geo-fencing for responsible use of spatial data from vehicles

Hi Ted,

OGC staff contributed to the requirements assessment for the Unmanned Aerial Systems work in ANSI (see the roadmap here: <>). There are standards that can be used to represent a geofence, but no standard to exactly describe a geofence in general (there are specs for various industries for domain-specific fencing).

In short, geofences may be defined in increasingly complex ways, starting with a point and radius to a box to an arbitrary polygon to a buffer around a corridor…. And those fences can be 2D or 3D in geometry and have temporal characteristics for a period of validity. Finally, geofences include or exclude, e.g., leaving a fenced area can result in a trigger or entering a fenced area can trigger an action.

Best Regards,
