In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).
SENTINEL1 features specify a matrix of x and y coordinates as longitude and latitude. For each SENTINEL1 dataset, there will only be a single feature returned.
Each band uses the UInt16 type, but in some datasets only the bottom 8 bits (representing the values 0-255) are used.
Tip: In FME, a RasterBandInterpretationCoercer can be used to cast the values to an 8-bit type such as Gray8. This is useful for achieving contrast in the images, since otherwise they may appear entirely black.
User attributes are not supported.

Contents |
|---|---|
|
sentinel1_type |
This will always be sentinel1_raster. |
|
sentinel1_acquisition_start_time |
The time at beginning of sensing. |
|
sentinel1_acquisition_stop_time |
The time at end of sensing. |
|
sentinel1_band{}.polarisation |
The polarization of this image band, where index in the list represents the index of the band as read from the dataset. Possible values are HH, HV, VH, and VV. |
|
sentinel1_beam_mode |
The acquisition mode. Possible values are SM, IW, EW, and WV. |
|
sentinel1_beam_swath |
Identifies the beam when in SM mode. Otherwise this is the same as sentinel1_beam_mode. Possible values are S1-S6, IW, EW, and WV. |
|
sentinel1_facility_identifier |
The name of the ground facility communicating with the satellite. |
|
sentinel1_line_spacing |
Azimuth sample spacing between pixels, in meters. |
|
sentinel1_mission_id |
The mission identifier denoting the satellite. |
|
sentinel1_mode |
Identifies the beam when in SM mode. Otherwise this is the same as sentinel1_beam_mode. Possible values are S1-S6, IW, EW, and WV. |
|
sentinel1_orbit_direction |
The direction of the orbit. Possible values are ASCENDING and DESCENDING. |
|
sentinel1_orbit_number |
The absolute orbit number. |
|
sentinel1_pixel_spacing |
Range sample spacing between pixels, in meters. |
|
sentinel1_product_type |
The product type. This should be GRD. |
|
sentinel1_satellite_identifier |
The satellite identifier. |
|
sentinel1_sensor_identifier |
The sensor identifier. |
|
sentinel1_swath |
The swath identifier.
