Description

Example product NISAR_L2_PR_GUNW_024_026_D_065_026_4000_SH_20260628T001542_20260628T001617_20260722T001541_20260722T001616_P05023_N_F_J_001 : https://search.earthdata.nasa.gov/search/granules?p=C2854335566-ASF&pg[0][v]=f&pg[0][id]=NISAR_L2_PR_GUNW_024_026_D_065_026_4000_SH_20260628T001542_20260628T001617_20260722T001541_20260722T001616_P05023_N_F_J_001&pg[0][gsk]=-start_date&q=nisar%20gunw

The frame is labelled as a full frame product, but overviews and data in the file suggest partial coverage only.

The corresponding GCOV
NISAR_L2_PR_GCOV_026_026_D_065_4005_DHDH_A_20260722T001541_20260722T001616_P05023_N_F_J_001 also appears to be labelled as full frame even though coverage appears to be partial.

Research direction

Start with the linked GUNW and GCOV product examples and their overviews and metadata, then locate the logic that labels frames as partial or full. Compare the recorded coverage with those labels and determine the expected classification; done means both examples receive labels consistent with their actual coverage.
