Announcement: On November 13, 2024, all users will need to use a Cloud project in order to access Earth Engine. After this date, continued individual access without a Cloud project will require an exception.

Method: projects.image.export

Initiates a batch process that computes an image and writes the result to one of several destinations.

HTTP request

POST https://earthengine.googleapis.com/v1alpha/{project=projects/*}/image:export

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters

Parameters
`project`	`string` The project id or project number of the Google Cloud Platform project that should be treated as the service consumer for this request. Format is `projects/{project-id}`. Authorization requires the following IAM permission on the specified resource `project`: `earthengine.exports.create`

project

string

The project id or project number of the Google Cloud Platform project that should be treated as the service consumer for this request. Format is projects/{project-id}.

Authorization requires the following IAM permission on the specified resource project:

earthengine.exports.create

Request body

The request body contains data with the following structure:

{ "expression": { object (`Expression`) }, "description": string, "maxPixels": string, "grid": { object (`PixelGrid`) }, "requestId": string, "workloadTag": string, "priority": integer, // Union field `export_options` can be only one of the following: "fileExportOptions": { object (`ImageFileExportOptions`) }, "assetExportOptions": { object (`ImageAssetExportOptions`) } // End of list of possible types for union field `export_options`. }

{
  "expression": {
    object (Expression)
  },
  "description": string,
  "maxPixels": string,
  "grid": {
    object (PixelGrid)
  },
  "requestId": string,
  "workloadTag": string,
  "priority": integer,

  // Union field export_options can be only one of the following:
  "fileExportOptions": {
    object (ImageFileExportOptions)
  },
  "assetExportOptions": {
    object (ImageAssetExportOptions)
  }
  // End of list of possible types for union field export_options.
}

Fields
`expression`	`object (Expression)` An expression that evaluates to the image to compute and export.
`description`	`string` A human-readable name of the task.
`maxPixels`	`string (Int64Value format)` The maximum number of pixels to compute and export. This is a safety guard to prevent you from accidentally starting a larger export than you had intended. The default value is 1e8 pixels, but you can set the value explicitly to raise or lower this limit.
`grid`	`object (PixelGrid)` Parameters describing how the image computed by `expression` should be reprojected and clipped. If not present, the full computed image is returned in its native projection.
`requestId`	`string` A unique string used to detect duplicated requests. If more than one request is made by the same user with the same non-empty `requestId`, only one of those requests may successfully start a long-running operation. `requestId` may contain the characters a..z, A..Z, 0-9, or '-'. `requestId` may be at most 60 characters long.
`workloadTag`	`string` User supplied label to track this computation.
`priority`	`integer` Optional. The priority of the export task within the project. Higher priority tasks are scheduled sooner. Must be an integer between 0 and 9999. Defaults to 100 if not set.
Union field `export_options`. Options describing where and how to store the results. `export_options` can be only one of the following:
`fileExportOptions`	`object (ImageFileExportOptions)` If specified, configures export as a file.
`assetExportOptions`	`object (ImageAssetExportOptions)` If specified, configures export as an Earth Engine asset.

Response body

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

Authorization scopes

Requires one of the following OAuth scopes:

https://www.googleapis.com/auth/earthengine
https://www.googleapis.com/auth/cloud-platform
https://www.googleapis.com/auth/devstorage.full_control

For more information, see the Authentication Overview.

ImageAssetExportOptions

Options for saving images as Earth Engine assets.

}

Fields
`pyramidingPolicy`	`enum (PyramidingPolicy)` The pyramiding policy to apply by default to all bands.
`pyramidingPolicyOverrides`	`map (key: string, value: enum (PyramidingPolicy))` Specific per-band pyramid policy overrides. An object containing a list of `"key": value` pairs. Example: `{ "name": "wrench", "mass": "1.3kg", "count": "3" }`.
Union field `destination`. Where to write the results. `destination` can be only one of the following:
`earthEngineDestination`	`object (EarthEngineDestination)` If specified, configures export to Earth Engine.
