Method: projects.assets.listAssets

  • The GET request to https://earthengine.googleapis.com/v1/{parent=projects/*/assets/**}:listAssets is used to list assets within a specified container.

  • The parent path parameter is required and specifies the container asset to list, accepting formats like "projects/" or "projects//assets/**".

  • Optional query parameters like pageSize, pageToken, filter, and view can be used to refine the list of assets returned.

  • The request body must be empty, and a successful response will contain an instance of ListAssetsResponse.

  • Authorization requires specific IAM permissions on the parent resource or one of several OAuth scopes.

Lists any container asset, such as a folder or collection.

HTTP request

GET https://earthengine.googleapis.com/v1/{parent=projects/*/assets/**}:listAssets

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
parent

string

Required. The name of the container asset to list. parent is of the format "projects/*" or "projects/*/assets/**" (e.g., "projects/[PROJECT]" or "projects/earthengine-legacy/assets/users/[USER]/[ASSET]"). All user-owned assets are currently under the project "earthengine-legacy" (e.g., "projects/earthengine-legacy/assets/users/foo/bar"). All other assets are under the project "earthengine-public" (e.g., "projects/earthengine-public/assets/LANDSAT"). If "projects/earthengine-legacy" is specified, the response will consist of a list of all top-level folders owned by the requesting user.

Authorization requires one or more of the following IAM permissions on the specified resource parent:

  • earthengine.assets.get
  • earthengine.assets.list

Query parameters

Parameters
pageSize

integer

The maximum number of results per page. The server may return fewer assets than requested. If unspecified, the page size default depends on the EarthEngineAssetView, with higher limits for more restrictive views.
pageToken

string

A token identifying a page of results the server should return. Typically this is the value of ListAssetsResponse.next_page_token returned from the previous call to the assets.listAssets method.
filter

string

If present, specifies a filter. Filters are only applied to ImageCollection assets and are ignored for Folder assets.

The fields startTime, endTime, and members of properties are recognized. The custom function intersects(str) is available, which allows filtering by geometry.

An example date filter:

"startTime>\"2020-01-01T00:00:00+00:00\" AND
endTime<\"2020-02-01T00:00:00+00:00\""

An example property filter:

"properties.CLOUDY_PIXEL_PERCENTAGE<30"

An example geometry filter:

"intersects(\"{'type':'Point','coordinates':[1,2]}\")"
"intersects(\"{\\\"type\\\":\\\"Point\\\",\\\"coordinates\\\":[1,2]}\")"

See https://google.aip.dev/160 for more details on the filter language.
view

enum (EarthEngineAssetView)

Specifies which parts of the EarthEngineAsset resource should be returned in the response. Only applies to ImageCollection assets. All elements of Folder assets will be encoded in the BASIC view regardless of the value of this field.

Request body

The request body must be empty.

Response body

If successful, the response body contains an instance of ListAssetsResponse.

Authorization scopes

Requires one of the following OAuth scopes:

  • https://www.googleapis.com/auth/earthengine
  • https://www.googleapis.com/auth/earthengine.readonly
  • https://www.googleapis.com/auth/cloud-platform
  • https://www.googleapis.com/auth/cloud-platform.read-only
