# GET /udl/groundimagery/tuple

`GET /udl/groundimagery/tuple`

## Request

- Base URL: `https://unifieddatalibrary.com`
- URL: `https://unifieddatalibrary.com/udl/groundimagery/tuple`
- Auth: none declared

Service operation to dynamically query data and only return specified columns/fields. Requested columns are specified by the 'columns' query parameter and should be a comma separated list of valid fields for the specified data type. classificationMarking is always returned. See the queryhelp operation (`/udl/<datatype>/queryhelp`) for more details on valid/required query parameter information. An example URI: /udl/elset/tuple?columns=satNo,period&epoch=>now-5 hours would return the satNo and period of elsets with an epoch greater than 5 hours ago.

## Query parameters

- `columns` string, required
- `imageTime` string, date-time, required
- `firstResult` integer
- `maxResults` integer

## Response `200`

OK

- GroundImageryFull[]
  - `id` string: Unique identifier of the record, auto-generated by the system.
  - `idSensor` string: Optional ID of the sensor that produced this ground image.
  - `classificationMarking` string, required: Classification marking of the data in IC/CAPCO Portion-marked format.
  - `imageTime` string, date-time, required: Timestamp the image was captured/produced.
  - `filename` string, required: Name of the image file.
  - `region` string: Geographical region or polygon (lon/lat pairs) of the image as projected on the ground in geoJSON or geoText format. This is an optional convenience field only used for create operations. The system will auto-detect the format (Well Known Text or GeoJSON) and populate both regionText and regionGeoJSON fields appropriately. When omitted, regionText or regionGeoJSON is expected.
  - `regionText` string: Geographical region or polygon (lon/lat pairs), as depicted by the Well-Known Text representation of the geometry/geography, of the image as projected on the ground. WKT reference: https://www.opengeospatial.org/standards/wkt-crs. Ignored if included with a create operation that also specifies a valid region.
  - `regionGeoJSON` string: Geographical region or polygon (lat/lon pairs), as depicted by the GeoJSON representation of the geometry/geography, of the image as projected on the ground. Reference: https://geojson.org/. Ignored if included with a create operation that also specifies a valid region or regionText.
  - `regionType` string: Type of region as projected on the ground.
  - `regionNDims` integer: Number of dimensions of the geometry depicted by region.
  - `regionSRid` integer: Geographical spatial_ref_sys for region.
  - `origSensorId` string: Optional identifier provided by source to indicate the sensor identifier used to detect this event. This may be an internal identifier and not necessarily a valid sensor ID.
  - `subjectId` string: Optional identifier of the subject/target of the image, useful for correlating multiple images of the same subject.
  - `name` string: Optional name/description associated with this image.
  - `source` string, required: Source of the data.
  - `origin` string: Originating system or organization which produced the data, if different from the source. The origin may be different than the source if the source was a mediating system which forwarded the data on behalf of the origin system. If null, the source may be assumed to be the origin.
  - `origNetwork` string: The originating source network on which this record was created, auto-populated by the system.
  - `sourceDL` string: The source data library from which this record was received. This could be a remote or tactical UDL or another data library. If null, the record should be assumed to have originated from the primary Enterprise UDL.
  - `dataMode` 'REAL' | 'TEST' | 'SIMULATED' | 'EXERCISE', required: Indicator of whether the data is REAL, TEST, EXERCISE, or SIMULATED data: REAL: Data collected or produced that pertains to real-world objects, events, and analysis. TEST: Specific datasets used to evaluate compliance with specifications and requirements, and for validating technical, functional, and performance characteristics. EXERCISE: Data pertaining to a government or military exercise. The data may include both real and simulated data. SIMULATED: Synthetic data generated by a model to mimic real-world datasets.
  - `createdAt` string, date-time: Time the row was created in the database, auto-populated by the system.
  - `createdBy` string: Application user who created the row in the database, auto-populated by the system.
  - `updatedAt` string, date-time: Read-only time the row was updated in the database, set automatically by the system on update.
  - `updatedBy` string: Application user who last updated the row in the database, set by the system automatically and ignored on create/edit operations.
  - `transactionId` string: Optional identifier to track a commercial or marketplace transaction executed to produce this data.
  - `tags` string[]: Optional array of provider/source specific tags for this data, where each element is no longer than 32 characters, used for implementing data owner conditional access controls to restrict access to the data. Should be left null by data providers unless conditional access controls are coordinated with the UDL team.
  - `keywords` string[]: Optional array of keywords for this image.
  - `notes` string: Description and notes of the image.
  - `format` string: Optional, field indicating type of image, NITF, PNG, etc.
  - `filesize` integer: Size of the image file. Units in bytes. If filesize is provided without an associated file, it defaults to 0.
  - `checksumValue` string: MD5 value of the file. The ingest/create operation will automatically generate the value.
