# List the avialable collections from the service

`GET /collections`

## Response `200`

Metdata about the Environmental data collections shared by this API.

- Collections
  - `links` Link[], required
    - `href` string, required — Supplies the URI to a remote resource (or resource fragment).
    - `rel` string, required — The type or semantics of the relation.
    - `type` string — A hint indicating what the media type of the result of dereferencing the link should be.
    - `hreflang` string — A hint indicating what the language of the result of dereferencing the link should be.
    - `title` string — Used to label the destination of a link such that it can be used as a human-readable identifier.
    - `length` integer
  - `timeStamp` string, date-time
  - `numberMatched` integer
  - `numberReturned` integer
  - `crs` string[] — a global list of CRS identifiers that are supported by spatial feature collections offered by the service
  - `collections` CollectionDesc[], required
    - `id` string, required — identifier of the collection used, for example, in URIs
    - `title` string — human readable title of the collection
    - `description` string — a description of the features in the collection
    - `attribution` string
    - `links` Link[], required
      - `href` string, required — Supplies the URI to a remote resource (or resource fragment).
      - `rel` string, required — The type or semantics of the relation.
      - `type` string — A hint indicating what the media type of the result of dereferencing the link should be.
      - `hreflang` string — A hint indicating what the language of the result of dereferencing the link should be.
      - `title` string — Used to label the destination of a link such that it can be used as a human-readable identifier.
      - `length` integer
    - `extent` Extent — unresolved $ref
    - `itemType` string — An indicator about the type of the items in the collection
    - `crs` string[] — the list of coordinate reference systems supported by the API; the first item is the default coordinate reference system
    - `storageCrs` string, uri — the CRS identifier, from the list of supported CRS identifiers, that may be used to retrieve features from a collection without the need to apply a CRS transformation
    - `storageCrsCoordinateEpoch` number — point in time at which coordinates in the spatial feature collection are referenced to the dynamic coordinate reference system in `storageCrs`, that may be used to retrieve features from a collection without the need to apply a change of coordinate epoch. It is expressed as a decimal year in the Gregorian calendar
