12 Spatial Filtering Profile
In this profile of the SOS 2.0, the observations offered by an SOS server are restricted to spatial observations which provide a well-defined parameter for carrying the sampling geometry of the
observation. If an SOS server follows this profile, spatial filters can target the sampling geometries of observations.
12.1 Requirements Class: Spatial Filtering Profile
Requirement 102 When an SOS server encounters an error while performing a GetResult operation, it
shall return an exception message as specified in Clause 15 of [OGC 09-001] with applicable exception code as defined in Listing 9. The meaning of each exception code shall be as defined in
OGC 06-121r3 and OGC 09-001.

The requirements class “Spatial Observation Data” http:www.opengis.netspecOMXML2.0reqSpatialObservation defined in [OGC 10-025]
Subclause 7.13 constrains the encoding of an observation to have one parameter which contains the sampling geometry of the observation. The sampling geometry represents the spatial extent
where the observation result applies to. This is usually the extent of the observations feature of interest but may also be computed or determined by other means.
Example 26 An example of such a spatial observation as defined by [OGC 10-025] with sampling location
parameter is shown here: ?xml version=1.0 encoding=UTF-8?

The following requirement restricts the observations served by an SOS server to be such spatial observations. The sampling geometry of an observation is encoded as a parameter of the
observation.
The
observedArea
provided in the
Capabilities
is restricted to represent the minimum bounding box of the sampling geometries of the observations.

13 Binding Extension
This Clause specifies concrete encodings and bindings for the operations of the SOS 2.0 standard. Those bindings describe how SOS 2.0 clients and servers can communicate with each other.
