Search the satellite imagery catalog

Costs 2 token(s) per request. Returns a minimal metadata projection of matching STAC scenes (Sentinel-1, Sentinel-2, NISAR L-band) — no imagery bytes, no signed URLs. bbox is required.

Query parameters

bboxstring required

Bounding box "minLon,minLat,maxLon,maxLat" (WGS84). Required.

collection'sentinel-1-grd' | 'sentinel-1-rtc' | 'sentinel-2-l2a' | 'NISAR_L2_GCOV_PROVISIONAL_V1'

Catalog collection. Defaults to sentinel-2-l2a.

start_datestring date

Date range start (YYYY-MM-DD, UTC) — the app's imagery date range. Give with end_date, or neither for the last 7 days. At most 30 days.

end_datestring date

Date range end (YYYY-MM-DD, UTC), inclusive.

event_datestring date

Event date YYYY-MM-DD (UTC). When set, each scene is tagged timing=pre/post/same_day_unknown, the window is widened to the canonical pre/post span, and meta reports has_pre_baseline / has_post / bracketing_available / window_status; for sentinel-1-grd it also reports sar_pair_status + orbit_note.

event_pointstring

Event point "lon,lat" (WGS84). When set, each scene reports target_relation (covers_event_geometry = geometry gate; usable_for_analysis additionally requires acceptable cloud for optical) so a scene that only clips the wide bbox — or a cloud-obscured optical scene — is not presented as usable for the event.

event_aoistring

Event AOI bbox "minLon,minLat,maxLon,maxLat" (WGS84) for target_relation.intersects_event_aoi / event_aoi_coverage_ratio.

event_timestampstring date-time

Full event timestamp (ISO 8601) when known — promotes same-day scenes from same_day_unknown to pre/post by time.

cloud_cover_maxnumber

Sentinel-2 only: max cloud cover percentage.

limitinteger

Max scenes to return.

Response

Matching scenes (minimal metadata).
