Announcement: All noncommercial projects registered to use Earth Engine before
April 15, 2025 must
verify noncommercial eligibility to maintain Earth Engine access.
Method: projects.imageCollection.computeImages
Stay organized with collections
Save and categorize content based on your preferences.
Computes a set of features by applying an arbitrary computation to features in one or more tables. Results are returned as a list of images.
HTTP request
POST https://earthengine.googleapis.com/v1/{project=projects/*}/imageCollection:computeImages
The URL uses gRPC Transcoding syntax.
Path 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.computations.create
|
Request body
The request body contains data with the following structure:
| JSON representation |
{
"expression": {
object (Expression)
},
"pageSize": integer,
"pageToken": string,
"workloadTag": string
} |
| Fields |
expression |
object (Expression)
The expression to compute.
|
pageSize |
integer
The maximum number of results per page. The server may return fewer images than requested. If unspecified, the page size default is 1000 results per page.
|
pageToken |
string
A token identifying a page of results the server should return. Typically, this is the value of ComputeImagesResponse.next_page_token returned from the previous call to the imageCollection.computeImages method.
|
workloadTag |
string
User supplied tag to track this computation.
|
Response body
Response message for EarthEngineService.ComputeImages.
If successful, the response body contains data with the following structure:
| JSON representation |
{
"images": [
{
object (EarthEngineAsset)
}
],
"nextPageToken": string
} |
| Fields |
images[] |
object (EarthEngineAsset)
The list of images matching the query.
|
nextPageToken |
string
A token to retrieve the next page of results. Pass this value in the ComputeImagesRequest.page_token field in the subsequent call to the imageCollection.computeImages method to retrieve the next page of results.
|
