The NASA-ISRO Synthetic Aperture Radar (NISAR) Geocoded Pixel Offsets (GOFF) product is a Level 2 product derived from the Range Doppler Pixel Offsets (ROFF) product by geocoding the pixel offset layers and its associated data layers (i.e., SNR) on a geographical grid at 80 m posting. Geocoding uses the orbit of the reference Range Doppler Single Look Complex (RSLC) product and a Digital Elevation Model (DEM) to project the data onto a pre-defined Universal Transverse Mercator (UTM) or Polar stereographic projection system map grid. The geocoding algorithm uses a bilinear interpolation for interpolating data layers with floating-point data types.

The GOFF product contains a collection of data layers representing the pixel offset shifts between a pair of coarsely coregistered RSLC granules. The spacing, the window size, and the search radius used to generate the pixel offset layers in the range-Doppler geometry are organized by range bandwidth and area of observation. Pixel offset layers are distributed without performing any conventional post-processing operation, i.e., layers might contain offset outliers and are not low pass filtered to reduce noise in the data.
