7.4.2.2 Checking the status of a task

The GetStatus operation is optional and should only be implemented if the server implements asynchronous processing. In this case, it allows a user to check the status of a task. The response is based on the StatusReport of the SPS specification [NR22].

7.4.2.3 Getting the segments of a task

The GetTask operation provides access to the results of a feasibility task that has been completed. The response to this request is based on the same structures as the response to a GetFeasibility request: ‐ StatusReport: a summary of the status of the task. It contains the ID of the task, the sensor used, the status of the task and the parameters provided in the tasking request. ‐ FeasibilityStudy: the result of a feasibility analysis. It is composed of a list of segments. The Segment structure contains the full description of an acquisition, including the footprint describing the area covered, the time of acquisition, the sensor used and its mode. It can also be extended to contain additional information, e.g. Downlink information, cloud coverage, etc.

7.4.2.4 Submitting segments for planning

The SebmitSegmentByID operation allows the user to use the results of a feasibility analysis in order to submit the segments for planning. This request requires the following information: ‐ taskId: the ID of the task containing the segments that the user wants to submit. ‐ segmentId multiple: a list of segment identifiers. This identifier is part of the Segment structure as defined in the EO-SPS specification [NR22]. This operation will create a planning task that will be available in the Planning resource 7.5 below. The response to the operation will include the following elements: ‐ StatusReport: a summary of the status of the task. It contains the ID of the task, the sensor used, the status of the task and the parameters provided in the tasking request. ‐ ProgrammingStatus: this structure describes the results of the submission. It is similar to the FeasibilityStudy as it also composed of a list of Segments. Its full description is available in the EO-SPS specification [NR22]. 49 Copyright © 2014 Open Geospatial Consortium
