13. DescribeGetFeasibility operation optional, synchronous
13.1. Introduction
The DescribeGetFeasibility operation allows SPS clients to request the information necessary to prepare a programming request targeted at the sensors that are supported by the SPS and that are
selected by the client. The server will return information about all parameters that have to be set by the client in order to perform a GetFeasibility operation and eventually the description of
parameters returned in the GetFeasibility response. The only additional parameter “SensorID” defines the specific sensors that shall be described by the server. This allows servers to façade
multiple sensors that require parameterization and return all information to the client using one call only.
Because GetFeasibility operation is optional, DescribeGetFeasibility is also optional.
13.2. EO profile specific
This operation is inherited of the OGC 07-014 operation DescribeTasking.
TaskingDescriptor
has been renamed
ParameterDescriptor
and has been modified see § 9.1.
The DescribeGetFeasibility response contains two elements :
InputParameters
list and description of parameters required to perform a GetFeasibility and
OutputParameters
list and description of parameters returned in the GetFeasibility response.
