Resolve SAR metadata interfaces
Refactor image metadata interface for SAR sensors. The metadata are now read by gdal instead of ossim. Concerned sensors are :
- SAR IMI: TerraSar
- SAR IMI: CosmoSkyMed
- SAR IMI: Radarsat2
The metadata parsed are :
- For CosmoSkyMed:
- AcquisitionStartTime
- AcquisitionStopTime
- Mission
- Mode
- ProductType
- SensorID
- Instrument
- RadarFrequency
- OrbitDirection
- OrbitNumber
- Polarization
- Swath
- PRF
- SAR Orbits geom
- For TerraSar:
- AcquisitionStartTime
- AcquisitionStopTime
- Mission
- Mode
- ProductType
- SensorID
- RadarFrequency
- OrbitDirection
- OrbitNumber
- PRF
- PSF
- Polarization for each band
- LineSpacing
- PixelSpacing
- For RadarSat2:
- AcquisitionStartTime
- Mission
- BeamMode
- ProductType
- Instrument
- SensorID
- RadarFrequency
- OrbitDirection
- PRF
- PSF
- CenterIncidenceAngle
- Polarization for each band
- ProductionDate
- LineSpacing
- PixelSpacing
- NumberOfLines
- NumberOfColumns
- AverageSceneHeight
Three tests have been added, one for each satellite (see ioTvImageMetadataInterfaceTest_Radarsat2, ioTvImageMetadataInterfaceTest_TerraSar and ioTvImageMetadataInterfaceTest_TerraSar).
