| Field | Description | Data Type |
|---|---|---|
| acquired | Timestamp representing the nominal date and time of acquisition (in UTC). | datetime |
| camera_id | enum-string | |
| geometry | Geospatial extent of image, represented as a geo-json Polygon vs Multi-Polygon. | geometry |
| gsd | The ground sampling distance of the image acquisition. | float |
| id | Provider-specific unique identifier | string |
| item_type | The identifier of the asset | string |
| provider | Imagery Provider, as a member of the enum of known providers. | enum-string |
| published | Timestamp representing the first publish of the item id (in UTC). | datetime |
