EO Satellite Tasking Extension for SPS OGC 10-135 «DataType» Core Tasking Parameters:: AcquisitionParameters «DataType» AcquisitionParametersOPT «property» + GroundResolution: RealPair [0..1] + InstrumentMode: ScopedName [0..1] + FusionAccepted: Boolean [0..1] + MinLuminosity: Real [0..1] Figure 18 – UML diagram of the AcquisitionParametersOPT class Name Description Type unit GroundResolution The ground resolution is the distance between two contiguous pixels of remote sensed imagery when projected on the earth. This parameter allows the user to select a range of acceptable ground resolutions. Real Pair meter InstrumentMode A categorical value used to specify a particular instrument configuration. All possible modes should be defined in a code space, usually specific to the type of instrument. ScopedName FusionAccepted Specifies if imagery obtained by fusing several images acquired separately and co-registered is acceptable. Boolean MinLuminosity Minimum luminosity acceptable for the acquired imagery. This constrains the solar incidence angle of the acquired imagery. Real
