Request body

The request body contains data with the following structure:

JSON representation
{
  "expression": {
    object (Expression)
  },
  "pageSize": number,
  "pageToken": string
}
Fields
expression

object (Expression)

The expression to compute.

pageSize

number

An optional maximum number of results per page. The server may return fewer features than requested. If unspecified, server will pick an appropriate default.

pageToken

string

An optional token identifying a page of results the server should return. Typically, this is the value of ComputeFeaturesResponse.next_page_token returned from the previous call to the table.computeFeatures method.

Response message for EarthEngineService.ComputeFeatures.

JSON representation
{
  "type": string,
  "features": [
    {
      object (Feature)
    }
  ],
  "nextPageToken": string
}
Fields
type

string

Always contains the constant string "FeatureCollection", marking this as a GeoJSON FeatureCollection object.

features[]

object (Feature)

nextPageToken

string

A token to retrieve the next page of results. Pass this value in the ComputeFeaturesRequest.page_token field in the subsequent call to the table.computeFeatures method to retrieve the next page of results.
