EO Satellite Tasking Extension for SPS OGC 10-135
status Status code describing the state of this segment. Descriptions of
status codes are given in the table below. The value shall be ‘POTENTIAL’ in the case of a feasibility study.
StatusCode CodeList
relatedSegment Reference to
a coupled segment such as the other member of a stereo or interferometric pair.
Segment by reference
extension Extension slot for mission specific information or future extensions
to this standard. Any
The table below describes the meaning of status codes used in the Segment class:
Name Description
POTENTIAL Segments are marked as potential when they are estimated in the context of a feasibility
study. PLANNED
The segment is planned for acquisition at the specified date. This usually means that the segment has been entered in the satellite work plan but has not yet been executed.
ACQUIRED The segment was acquired by the on-board instrument and successfully downlinked to a
ground station. VALIDATED
The acquired segment was validated since it satisfied the validation criteria expressed in the request e.g. cloud cover was less than the maximum acceptable amount.
CANCELLED The segment acquisition was cancelled by the requester.
REJECTED An originally planned or potential segment acquisition was purposely cancelled by the data
provider because of a last minute conflict. FAILED
The acquisition of a segment failed for an internal reason such as a last minute conflict or a low image quality resulting from bad downlink transmission.
The Polygon class is defined in [OGC 07-036]. The EarthObservationEquipment class is defined in [OGC 10-157].
