Summary

  • Layers panel row Sentinel-1 SAR (Cloud-Penetrating), checkbox default OFF, id sentinel-1-sar.
  • On enable: GET /api/map/sentinel1?bbox= then L.tileLayer(tileUrl) at opacity 0.8, maxZoom 18. Uses the backend tileUrl as-is (same-origin /titiler/...). No Planetary Computer / titiler.xyz from the browser.
  • 404 no_imagery → map-hint, no layer. 429/502/network → HUD retry-later. Uncheck removes the layer. While ON, debounced moveend refetches and swaps tiles.

Test plan

  • pytest tests/test_sentinel1_frontend.py (contract: default off, no STAC, HUD errors)
  • Toggle ON over a land viewport → SAR tiles; OFF removes them
  • Empty ocean 404 shows: No Sentinel-1 imagery for this view in the last 7 days.
## Summary - Layers panel row **Sentinel-1 SAR (Cloud-Penetrating)**, checkbox default OFF, id `sentinel-1-sar`. - On enable: `GET /api/map/sentinel1?bbox=` then `L.tileLayer(tileUrl)` at opacity 0.8, maxZoom 18. Uses the backend tileUrl as-is (same-origin `/titiler/...`). No Planetary Computer / titiler.xyz from the browser. - 404 `no_imagery` → map-hint, no layer. 429/502/network → HUD retry-later. Uncheck removes the layer. While ON, debounced `moveend` refetches and swaps tiles. ## Test plan - [ ] pytest `tests/test_sentinel1_frontend.py` (contract: default off, no STAC, HUD errors) - [ ] Toggle ON over a land viewport → SAR tiles; OFF removes them - [ ] Empty ocean 404 shows: No Sentinel-1 imagery for this view in the last 7 days.
