For more information, see `urn:ogc:def:crs:OGC:1.3:AUTO42001:99:8888`, definded by OGC ([Definition identifier URNs in OGC namespace](https://portal.ogc.org/files/?artifact_id=24045)).\n\n## Electro-Optical / Raster Extension \n\n### eo:bands / raster:bands\n\n| Field name | Data Type | Description |\n| ---------- | --------- | ----------- |\n| openeo:gsd | [GSD Object](#GSD-Object) | An array containing GSD value and unit. |\n\n* For EO data the field is added to `eo:bands` entries.\n* For SAR and non-optical data the field is added to `raster:bands` entries.\n\n#### GSD Object\n\n| Field name | Data Type | Description |\n| ---------- | --------- | ----------- |\n| value      | \\[number] | **REQUIRED.** Collection's default pixel spacing in [x/y] direction in the unit of the reference_system specified in the datacube extension. Conversion factor between m and degrees (111 km = 1°) |\n| unit       | string    | **REQUIRED.** Specifies the unit of the value field within the GSD object. One of `m` (meter) or `°` (degree). |\n\n## Data Processing\n\nFor Items and Collections provided as batch job results:\n\n| Field name    | Data Type | Description |\n| ------------- | --------- | ----------- |\n| openeo:status | string    | Indicates the status of the underlying batch job processing, must be one of `running`, `canceled`, `finished`, `error`. For example, this can be used to indicate whether a STAC resource is complete (`finished`) or potentially incomplete (all other states). |\n\n## Collection filtering\n\n| Field name              | Data Type | Description |\n| ----------------------- | --------- | ----------- |\n| openeo:property_filters | \\[string] | Returns a list of properties you can filter on when loading data from the collection. Returning an empty array means that no property-based filters are available. This is a guide for users to get an overview of the available properties to filter by. More metadata about the properties can be found in `summaries`. |\n\n## Links (Web Map Links)\n\nLinks to WMTS and XYZ services can be provided through the [Web Map Links](https://github.com/stac-extensions/web-map-links) extension.\nInitially defined within the openEO platform project for openEO, but it has been split apart into a separate extension that is fully compliant to what is used in openEO.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopen-eo%2Fopeneo-stac-extensions","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fopen-eo%2Fopeneo-stac-extensions","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopen-eo%2Fopeneo-stac-extensions/lists"}
