Satellite before/after / change detection / Sentinel-2 time-series diff / construction monitoring / deforestation tracker / fire-burn-scar imagery. Renders two cloud-free Sentinel-2 composites of the same bounding box anchored at two dates, each averaged over the window_days prior. Returns both base64 PNGs side-by-side so clients can display, animate, or pixel-diff them. Use cases: construction-site progress, vegetation change, wildfire burn scars, port/parking-lot activity, glacier retreat. Native 10m. Bbox area ≤ 4 sq-deg.
INPUT — request schema
| property | type | description | req? |
|---|---|---|---|
| bbox | array | [west, south, east, north] in WGS84 lon/lat. west<east, south<north, area ≤ 4 sq-deg. | required |
| date_a | string | Anchor date for the BEFORE composite, YYYY-MM-DD. Must be earlier than date_b. | required |
| date_b | string | Anchor date for the AFTER composite, YYYY-MM-DD. | required |
| window_days | number | Days prior to each anchor used to build the cloud-free composite. 7-90. Default 30. | optional |
| size | number | Output image LONG-side length in pixels. 64-2500. Default 512. Short side scales by aspect. | optional |
| max_cloud_coverage | number | Per-scene max cloud cover percentage. 0-100. Default 30. | optional |
OUTPUT — response shape
| field | type | description |
|---|---|---|
| source | string | Imagery provider used for both composites, typically Sentinel-2 L2A via the configured STAC backend. |
| bbox | string | Echoed bounding box as minLon,minLat,maxLon,maxLat in WGS84 degrees covering the scene area. |
| window_days | string | Number of days prior to each anchor date averaged into a cloud-free composite. |
| max_cloud_coverage | string | Maximum per-scene cloud percentage allowed when selecting tiles for each composite. |
| size | string | Rendered pixel dimensions of each PNG as widthxheight at native 10m sampling. |
| format | string | Image encoding of the two composites, always png for this endpoint. |
| content_type | string | MIME type of the embedded image payloads, image/png. |
| before | string | Base64-encoded PNG of the earlier composite anchored at the before date. |
| after | string | Base64-encoded PNG of the later composite anchored at the after date. |
| license | string | Sentinel-2 data license string, typically CC BY-SA 3.0 IGO for Copernicus imagery. |
| attribution | string | Required attribution string crediting Copernicus Sentinel data and the processing source. |
