|
|
| Six display-only samples: three earthquake and three volcano examples, one per existing review tier: Fair, Good, and Excellent. These are descriptive labels for the original reviewer ratings, not new measurements or coverage categories. Within each tier, selection uses the middle shared-coverage rank among remaining distinct events. This is an illustrative selection, not a random statistical sample. |
|
|
| Each image shows all five acquisition-pair stages and all available orbits. Columns are stages; rows are reference VV, secondary VV, coherence, and wrapped phase. Checkerboards mark missing pixels. Shared coverage intersects VV, coherence and phase over every saved stage and orbit; panel labels are individual raster coverage. |
|
|
| VV uses one shared 2nd–98th percentile linear stretch per patch. Coherence uses 0–1 (viridis); phase uses −π–π (cyclic twilight). Previews are downsampled with nearest-neighbor sampling and JPEG encoded for display; the released arrays remain lossless. VH, DEM, slope and incidence are included in the dataset but omitted from this gallery. |

| ### Review rating distribution |
|
|
| Counts cover the full released dataset, not just the six examples. Review ratings and valid coverage are separate measures. |
