A GeoProximityType represents a circular area. This type is derived from the abstract base type GeoAreaType.
The ProximityType has the following attributes:
Center of the circular area.
WGS-84 / degrees with (-90 <= Latitude <=90)
WGS-84 / degrees with (-180 <= Longitude <=180)
Radius in meters
Query Parameter Representation
The GeoProximityType can be represented in query strings as follows:
<Latitude> + "," + <Longitude> (+ "," + <Radius>)?
If possible, i.e. if there is no risk of name clashes, the preferred name for the parameter of a ProximityType element is "prox".
