NISAR Provisional Geocoded Single Look Complex Product (Version 1)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/nil2gslc-p1
The NASA-ISRO Synthetic Aperture Radar (NISAR) Geocoded Single Look Complex (GSLC) product is a Level 2 product derived from the Level 1 Range Doppler Single Look Complex (RSLC) product by geocoding the input RSLC into a geocoded map coordinate system such as the UTM/Polar stereographic projection system.
Description
The geocoding is performed by inverse mapping of the map coordinates with their topographic heights into the radar coordinate system and interpolating the radar signal at the radar location corresponding to the map coordinate.
Phase preserving complex interpolation projects the data onto a uniformly spaced, north-south/east-west aligned geographic grid. The phase of the GSLC product is flattened for the orbit used in the RSLC processing. The phase flattening removes the topographic phase contribution in the GSLC.

Consequently, cross-multiplying two GSLC products will result in an interferometric phase flattened interferogram. The products in this collection are considered Provisional products and are intended to facilitate data exploration and process studies that do not require rigorous validation. These data are partially validated, and improvements are continuing; quality may not be optimal since validation and quality assurance are ongoing.
