The SLC parameter file contains metadata related to processing the GPRI raw data. A number of the
keyword:value parameters are GPRI specific. The keywords of these parameters are all prefixed with
GPRI. Most significant of these parameters are the starting azimuth rotation angle for the image and the
spacing between image lines.
The positional information for the GPRI position are contained in the
GPRI_ref_north
(latitude in
decimal degrees),
GPRI_ref_east
(longitude in decimal degrees) and
GPRI_ref_alt
(geoidal height in
meters) parameters. The height of the geoid relative to the WGS84 ellipsoid is in the GPRI_geoid
