VMTI-Oriented Perspective Observation Specializations
Figure 7: UML model of the VMTIObservation
The VMTIObservation itself is derived from OM_ComplexObservationgrey element in Figure 7 and therefore provides a number of attributes that shall be further defined
here:
phenomenonTime: this mandatory parameter shall be used to encode the timestamp from the VMTI KLV element. This is according to OM: “the
attribute phenomenonTime:TM_Objectshall describe the time that the result applies to the property of the feature-of-interest” OM.
resultTime: this mandatory parameter shall provide the same time as the phenomenonTime. If the observation data is the result of further VMTI data
processing, the time when the final result was assigned could be provided alternatively.
validTime: this optional parameter shall according to OM to “describe the time period during which the result is intended to be used” OM. It does not
have any equivalent in KLV VMTI.
resultQuality: this optional parameter shall only be used if quality information in addition to the quality information provided in elements of the result set can
be provided. It does not have any equivalent in KLV VMTI.
