SosFeatureOfInterest.Rd
Element in a GetObservation request to a Sensor Observation service to constrain the observations to be returned regarding the observed feature.
SosFeatureOfInterest(objectIDs = list(NA), spatialOps = NULL)
objectIDs | A list of character identifiers of features in a SOS. |
---|---|
spatialOps | An object of class |
Objects can be created by calls to the construction function of the form SosFeatureOfInterest(...)
.
SosFeatureOfInterestOrNULL
is a virtual class to model optional slots of containing elements: No objects may be created from them.
objectIDs
:Object of class "list"
: Identifiers of features of interest.
spatialOps
:Object of class "OgcSpatialOpsOrNULL"
: A spatial filtering of the result.
Class "SosFeatureOfInterestOrNULL"
, directly.
signature(obj = "SosFeatureOfInterest", sos = "ANY")
: Convert the object to a XML representation.
Specifies the feature for which observations are requested. This can either be represented by a reference to a feature ID advertised in the capabilities document or can be a spatial constraint.
