15 April 2025 harus
memverifikasi kelayakan nonkomersial untuk mempertahankan akses Earth Engine.
Method: projects.imageCollection.computeImages
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Menghitung kumpulan fitur dengan menerapkan komputasi arbitrer ke fitur dalam satu atau beberapa tabel. Hasil ditampilkan sebagai daftar gambar.
Permintaan HTTP
POST https://earthengine.googleapis.com/v1alpha/{project=projects/*}/imageCollection:computeImages
URL menggunakan sintaksis gRPC Transcoding.
Parameter jalur
| Parameter |
project |
string
Project ID atau nomor project project Google Cloud Platform yang harus diperlakukan sebagai konsumen layanan untuk permintaan ini. Format adalah projects/{project-id}.
Otorisasi memerlukan izin IAM berikut pada resource project yang ditentukan:
earthengine.computations.create
|
Isi permintaan
Isi permintaan memuat data dengan struktur berikut:
| Representasi JSON |
{
"expression": {
object (Expression)
},
"pageSize": integer,
"pageToken": string,
"workloadTag": string
} |
| Kolom |
expression |
object (Expression)
Ekspresi yang akan dihitung.
|
pageSize |
integer
Jumlah maksimum hasil per halaman. Server mungkin menampilkan lebih sedikit gambar dari yang diminta. Jika tidak ditentukan, ukuran halaman defaultnya adalah 1.000 hasil per halaman.
|
pageToken |
string
Token yang mengidentifikasi halaman hasil yang harus ditampilkan server. Biasanya, ini adalah nilai ComputeImagesResponse.next_page_token yang ditampilkan dari panggilan sebelumnya ke metode imageCollection.computeImages.
|
workloadTag |
string
Tag yang diberikan pengguna untuk melacak komputasi ini.
|
Isi respons
Pesan respons untuk EarthEngineService.ComputeImages.
Jika berhasil, isi respons memuat data dengan struktur berikut:
| Representasi JSON |
{
"images": [
{
object (EarthEngineAsset)
}
],
"nextPageToken": string
} |
| Kolom |
images[] |
object (EarthEngineAsset)
Daftar gambar yang cocok dengan kueri.
|
nextPageToken |
string
Token untuk mengambil halaman hasil berikutnya. Teruskan nilai ini di kolom ComputeImagesRequest.page_token dalam panggilan berikutnya ke metode imageCollection.computeImages untuk mengambil halaman hasil berikutnya.

Results are returned as a list of images.\n\n### HTTP request\n\n`POST https://earthengine.googleapis.com/v1alpha/{project=projects/*}/imageCollection:computeImages`\n\nThe URL uses [gRPC Transcoding](https://google.aip.dev/127) syntax.\n\n### Path parameters\n\n| Parameters ||\n|-----------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `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](https://cloud.google.com/iam/docs/) permission on the specified resource `project`: - `earthengine.computations.create` |\n\n### Request body\n\nThe request body contains data with the following structure:\n\n| JSON representation |\n|---------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ``` { \"expression\": { object (/earth-engine/reference/rest/v1alpha/Expression) }, \"pageSize\": integer, \"pageToken\": string, \"workloadTag\": string } ``` |\n\n| Fields ||\n|---------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `expression` | `object (`[Expression](/earth-engine/reference/rest/v1alpha/Expression)`)` The expression to compute. |\n| `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. |\n| `pageToken` | `string` A token identifying a page of results the server should return. Typically, this is the value of [ComputeImagesResponse.next_page_token](/earth-engine/reference/rest/v1alpha/projects.imageCollection/computeImages#body.ComputeImagesResponse.FIELDS.next_page_token) returned from the previous call to the `imageCollection.computeImages` method. |\n| `workloadTag` | `string` User supplied tag to track this computation. |\n\n### Response body\n\nResponse message for EarthEngineService.ComputeImages.\n\nIf successful, the response body contains data with the following structure:\n\n| JSON representation |\n|---------------------------------------------------------------------------------------------------------------------------------------|\n| ``` { \"images\": [ { object (/earth-engine/reference/rest/v1alpha/projects.assets#EarthEngineAsset) } ], \"nextPageToken\": string } ``` |\n\n| Fields ||\n|-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `images[]` | `object (`[EarthEngineAsset](/earth-engine/reference/rest/v1alpha/projects.assets#EarthEngineAsset)`)` The list of images matching the query. |\n| `nextPageToken` | `string` A token to retrieve the next page of results. Pass this value in the [ComputeImagesRequest.page_token](/earth-engine/reference/rest/v1alpha/projects.imageCollection/computeImages#body.request_body.FIELDS.page_token) field in the subsequent call to the `imageCollection.computeImages` method to retrieve the next page of results. |\n\n### Authorization scopes\n\nRequires one of the following OAuth scopes:\n\n- `https://www.googleapis.com/auth/earthengine`\n- `\n https://www.googleapis.com/auth/earthengine.readonly`\n- `\n https://www.googleapis.com/auth/cloud-platform`\n- `\n https://www.googleapis.com/auth/cloud-platform.read-only`\n\nFor more information, see the [OAuth 2.0 Overview](/identity/protocols/OAuth2)."]]
