<complexType name="AbstractObservationType">
<annotation>
<documentation>Base type for Observations.
Because of the well-known inconsistency in the implementation of XML Schema "restriction"
derivation,
this type is provided as a parent for all concrete observation types.
Concrete Observation types must extend this with a "result" of the appropriate type.
The following properties are inherited from EventType:
<!-- from AbstractGMLType
<element ref="gml:metaDataProperty" minOccurs="0" maxOccurs="unbounded"/>
<element ref="gml:description" minOccurs="0"/>
<element ref="gml:name" minOccurs="0" maxOccurs="unbounded"/> -->
<!-- from AbstractFeatureType
<element ref="gml:boundedBy" minOccurs="0"/> -->
<!-- from EventType
<element name="eventParameter" type="swe:TypedValuePropertyType" minOccurs="0"
maxOccurs="unbounded"/>
<element name="time" type="om:TimeObjectPropertyType" nillable="true"/>
<element name="precedingEvent" type="gml:StringOrRefType" minOccurs="0"
maxOccurs="unbounded"/>
<element name="followingEvent" type="gml:StringOrRefType" minOccurs="0"
maxOccurs="unbounded"/> -->
In the context of an Observation, the interpretation of some of the properties shall be refined as
follows:
time - the date/Time at which the procedure was executed
location - the location of the procedure (sensor, intrument, computational engine) at the time of the
observation event
For "in situ" procedures the value of the location will usually be the same as the location of the
featureOfInterest.
For "remote" procedures the location will normally be removed from the location of the
featureOfInterest</documentation>

procedure.</documentation>

<annotation>
<documentation>Link to a description of the property or phenomenon whose value
is being described or estimated through observation
for example "wavelength", "grass-species", "power", "intensity in the waveband xy",
etc.
It is this feature-property that provides the (semantic) type of the observation.
Note that the description of the phenomenon may be quite specific and
constrained.
In general the precise details of the constraints describing the observe properties
require attention to the procedure used in making the observation:
e.g. an optical sensor typically has a wavelength-dependent response.
This property may be provided for client convenience, to allow comparison
between and aggregation of observations of the same property made using different procedures.</documentation>
