Datasets:
Event-SAR sample gallery
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.
| Event type | Fair | Good | Excellent | Total |
|---|---|---|---|---|
| Earthquake | 97 | 82 | 135 | 314 |
| Volcano | 23 | 52 | 27 | 102 |
