Earth Observation Evidence — NASA and Copernicus

Query current official NASA HLS and Copernicus Sentinel scene catalogs for one bounded area and time window. The Actor returns a receipt-bound multimodal evidence entry that agents and data teams can consume directly.

What you get

• official NASA HLS Landsat and Sentinel-2 catalog records;
• official Copernicus Sentinel-2 L2A and Sentinel-1 GRD catalog records;
• acquisition time, intersecting geometry, platform, instruments, cloud cover where published, nominal resolution, and official asset links;
• a separate query receipt for every selected source, including the response hash and retained count;
• endpoint-shape receipts that preserve observed keys and distinguish missing, explicit null, and explicit false fields even when the publisher still returns HTTP 200;
• source-rights and attribution receipts;
• coverage, freshness, entry, and run hashes;
• explicit SOURCE_UNAVAILABLE or SCOPE_INCOMPLETE state when a selected source fails.

The Actor queries public STAC metadata. It does not download imagery pixels, run object detection, identify a person, or claim that a catalog record proves ownership, permit status, legality, causation, damage, safety, or responsibility.

Quick start

{
  "aoiId": "orlando-demo-001",
  "bbox": [-81.45, 28.45, -81.25, 28.65],
  "startDate": "2026-08-01",
  "endDate": "2026-08-25",
  "sources": [
    "nasa_hls_landsat",
    "copernicus_sentinel_2_l2a"
  ],
  "maxItemsPerSource": 10,
  "maxCloudCover": 60
}

bbox is [west, south, east, north] in WGS84 coordinates. The Actor limits requests to 25 square degrees, 366 days, 100 items per source, and the four named official catalogs.

Output contract

The default dataset contains one civicdataforge.multimodal-evidence-entry.v1 object. Its observations keep official catalog-query receipts and individual Earth-observation scene records separate. SOURCE-MANIFEST v2 and RUN-RECEIPT are also written to the default key-value store. Each successful source entry includes a payload shape receipt and record-set shape receipt so publisher representation drift remains independently diffable from record-value changes.

Use coverage.complete_for_declared_scope before relying on the bounded query. A completed zero-result query means only that the named catalog returned no retained records for the exact area, time, source, and cloud filter; it is not a universal no-imagery claim.

Cloud-cover null, missing, blank, boolean and out-of-range values remain unknown; published numeric zero remains zero. Unknown cloud values are retained by the optional filter and counted in the source manifest. evidence_type, pixels_analyzed: false, typed asset links and bytes_retrieved: false distinguish catalog discovery from pixels or condition evidence. The source limit is enforced locally, and a next page is disclosed; this is a bounded sample.

Source and rights boundary

• NASA CMR STAC: NASA Earthdata
• Landsat reuse: USGS Landsat restrictions and redistribution
• Copernicus STAC: Copernicus Data Space STAC API
• Copernicus terms: Terms and conditions

CivicDataForge redistributes normalized public catalog metadata and official source links, not satellite imagery bytes or publisher-created visualizations. Upstream attribution remains attached to every observation.

Copernicus receipts now state review_required: Sentinel data and other portal content have different terms, and this adapter has not classified an individual STAC response's downstream redistribution rights. A reachable catalog or source link is not blanket reuse permission.
