7.3.2.1.3 SWE Common encoding

The following table and XML snippet describe how this tasking parameters group shall be encoded using the SWE Common Data Model: Field Name Definition Component AcquisitionParameters http:www.opengis.netdefpropertyOGC-EO0sarAcquisitionParametersSAR DataRecord GroundResolution http:www.opengis.netdefpropertyOGC-EO0GroundResolution QuantityRange InstrumentMode http:www.opengis.netdefpropertyOGC-EO0InstrumentMode No default code space is defined by this specification for SAR instruments since there does not seem to be a standard for naming SAR acquisition modes. A URL linking to the definitions of each listed mode shall thus be provided by each SAR implementation of EO-SPS. Category FusionAccepted http:www.opengis.netdefpropertyOGC-EO0FusionAccepted Boolean PolarizationMode http:www.opengis.netdefpropertyOGC-EO0sarPolarizationMode A default code space is defined by this specification “ http:www.opengis.netdefpropertyOGC-EO0sarPolarizationModes ” and should be used when applicable Category 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 by a code space, usually specific to the instrument in the case of SAR. ScopedName FusionAccepted Specifies if imagery obtained by fusing several images acquired separately and co-registered is acceptable. Boolean PolarizationMode ReceiveTransmit polarization mode of a SAR instrument. ScopedName Copyright © 2011 Open Geospatial Consortium 73
