| acquired | Timestamp representing the nominal date and time of acquisition (in UTC). | datetime |
| anomalous_pixels | Ratio of anomalous pixels. Pixels that have image quality issues documented in the quality taxonomy (e.g. hot columns). This is represented spatially within the UDM. | range-float |
| clear_confidence_percent | The estimated confidence of clear_percent. | range-integer |
| clear_percent | The percentage of the image clear of clouds. | range-integer |
| cloud_cover | Ratio of the area covered by clouds to that which is uncovered. | range-float |
| cloud_percent | The percentage of the image obscured by clouds. | range-integer |
| columns | Number of columns in the ortho image product. | integer |
| epsg_code | The identifier for the grid cell that the imagery product is coming from if the product is an imagery tile (not used if scene). | integer |
| geometry | Geospatial extent of image, represented as a geo-json Polygon vs Multi-Polygon. | geometry |
| ground_control | If the image meets the positional accuracy specifications this value will be true. If the image has uncertain positional accuracy, this value will be false. | boolean |
| gsd | The ground sampling distance of the image acquisition. | float |
| heavy_haze_percent | The percentage of the image containing heavy haze. | range-integer |
| id | Provider-specific unique identifier | string |
| instrument | The generation of the satellite telescope. | string |
| item_type | The identifier of the asset | string |
| light_haze_percent | The percentage of the image containing light haze. | range-integer |
| origin_x | ULX coordinate of the ortho product files in the "epsg_code" (UTM) coordinate system. The coordinate references the top left corner of the top left pixel. | float |
| origin_y | ULY coordinate of the ortho product files in the "epsg_code" (UTM) coordinate system. The coordinate references the top left corner of the top left pixel. | float |
| pixel_resolution | Pixel resolution of the ortho product files in meters. | range-float |
| 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 |
| publishing_stage | Metric for an item's publishing stage. 'Preview' items have not been rectified and may change substantially upon subsequent publish. 'Standard' items are rectified and subject to minimal change upon subsequent publish. 'Finalized' items are rectified and additional changes are not expected. | enum-string |
| quality_category | Metric for image quality. To qualify for 'standard' image quality an image must meet the following criteria: sun altitude greater than or equal to 10 degrees, off nadir view angle less than 20 degrees, and saturated pixels fewer than 20%. If the image does not meet these criteria it is considered 'test' quality. | enum-string |
| rows | Number of rows in the ortho image product. | integer |
| satellite_azimuth | Spacecraft off track pointing direction, in degrees (0-360) | range-float |
| satellite_id | human-readable identifier for the satellite(e.g. SSC11, 0c18, RapidEye-2, Sentinel-2A) | string |
| shadow_percent | The percentage of the image obscured by shadow. | range-integer |
| snow_ice_percent | The percentage of the image obscured by snow/ice. | range-integer |
| strip_id | Unique Identifier for the underlying RapidEye collect spanning the Item's capture. | string |
| sun_azimuth | Angle from true north to the sun vector projected on the horizontal plane in degrees. | range-float |
| sun_elevation | Elevation angle of the Sun in degrees. | range-float |
| updated | Timestamp representing the last update of the item id (in UTC). | datetime |
| view_angle | Spacecraft across track viewing angle used for imaging. | range-float |
| visible_confidence_percent | The estimated confidence of visible_percent. | range-integer |
| visible_percent | The sum of snow/ice, clear, light haze, and shadow percents. | range-integer |
