Catalog Collection

As described in the stac specification, the catalog contains collections which contain features.

All Collections

To get all collections and their features, the following query can be used:


query {
  collections {
    crs
    description
    features(bbox: [BBOX], dateTime: [DATETIME], offset: [OFFSET], limit: [LIMIT]) {
      contents {
        ...CollectionFeature
      }
      returned
      total
    }
    id
    itemType
    keywords
    license
    providers {
      description
      name
      roles
      url
    }
    title
  }
}

Single Collection

If the id is known, the same as above can be queried for a single collection:


query {
  collection(id: [COLLECTION_ID]) {
    crs
    description
    features(bbox: [BBOX], dateTime: [DATETIME], offset: [OFFSET], limit: [LIMIT]) {
      contents {
        ...CollectionFeature
      }
      returned
      total
    }
    id
    itemType
    keywords
    license
    providers {
      description
      name
      roles
      url
    }
    title
  }
}
