13.3 Requirements Class: GetFeatureOfInterest KVP Binding
This requirements class defines a KVP binding for the GetFeatureOfInterest operation. The here defined KVP binding of the GetFeatureOfInterest operation is a realization of the
conceptual model of that operation as defined in Subclause 9.1.1. In general, all requirements defined for the conceptual model of the GetFeatureOfInterest operation apply for its realization
as a KVP binding. However, due to the limitations of a KVP binding, the parameterization of the operation needs to be restricted and further defined as described below.

Requirement 118 The response behaviour of the GetObservation operation shall be as defined in
Subclause 8.3.2 of this document. If the response format chosen in the request requires that a
GetObservationResponse
be returned then it shall be encoded as defined in subclause 13.1

Requirement http:www.opengis.netspecSOS2.0reqkvp-foiRetrievalbbox-encoding
Requirement 120 For the KVP binding, a bounding box shall be used as
spatialFilter
as defined in the conceptual model of the GetFeatureOfInterest operation Subclause 9.1.1.
The encoding of the bounding box shall be a list of comma separated values. The first value shall be the
valueReference
that identifies the spatial property of the features to which this bounding box, as a spatial filter, is applied – following the requirements on ValueReference as defined by ISO
19143OGC 09-026r1. The following values shall be as defined in Subclause 10.2.3 of [OGC 06-121r3].
This results in the following encoding:
valueReference,minCoordinate1,minCoordinate2,...,minCoordinateN,maxCoordin ate1,maxCoordinate2,...,maxCoordinateN,crsURI
The
crsURI
is optional. An example value for
crsURI
is “
urn:ogc:def:crs:EPSG::4326
”.
