Below is a detailed specification of the endpoints exposed by the satellite imagery computational subsystem.
GET/v1/imagery/search
Query across all available sensor platforms (Sentinel-2, Landsat-8, MODIS) to find geo-referenced imagery matching coordinates and date boundaries.
Request Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
| bbox | string (array of float) | YES | Geographic bounding coordinates [MinLon, MinLat, MaxLon, MaxLat] in EPSG:4326. |
| start_date | string (ISO 8601) | YES | Starting date boundary for imagery coverage filters (e.g. '2026-05-01'). |
| end_date | string (ISO 8601) | YES | Ending date boundary for imagery coverage filters (e.g. '2026-06-01'). |
| cloud_cover_limit | float | NO | Filter out images with cloud coverage exceeding this ratio. Range [0.0 - 1.0]. Default: 0.2. |
