Pengumuman: Semua project nonkomersial yang terdaftar untuk menggunakan Earth Engine sebelum
15 April 2025 harus
memverifikasi kelayakan nonkomersial untuk mempertahankan akses Earth Engine.
Method: projects.assets.listFeatures
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Mencantumkan fitur dalam aset tabel. Metode ini memungkinkan pemanggil menerapkan filter spasial-temporal dan properti ke tabel. Hasil ditampilkan sebagai daftar objek fitur GeoJSON.
Permintaan HTTP
GET https://earthengine.googleapis.com/v1beta/{asset=projects/*/assets/**}:listFeatures
URL menggunakan sintaksis gRPC Transcoding.
Parameter jalur
| Parameter |
asset |
string
Wajib. Nama aset tabel yang akan dicantumkan. asset memiliki format "projects/*/assets/**" (misalnya, "projects/earthengine-legacy/assets/users/[USER]/[ASSET]"). Semua aset milik pengguna berada dalam project "earthengine-legacy" (mis., "projects/earthengine-legacy/assets/users/foo/bar"). Semua aset lainnya berada dalam project "earthengine-public" (misalnya, "projects/earthengine-public/assets/LANDSAT").
Otorisasi memerlukan izin IAM berikut pada resource asset yang ditentukan:
|
Parameter kueri
| Parameter |
pageSize |
integer
Jumlah maksimum hasil per halaman. Server mungkin menampilkan lebih sedikit aset daripada 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 ListFeaturesResponse.next_page_token yang ditampilkan dari panggilan sebelumnya ke metode assets.listFeatures.
|
region |
string
Jika ada, geometri yang menentukan wilayah kueri, yang ditentukan sebagai string geometri GeoJSON (lihat RFC 7946).
|
filter |
string
Jika ada, menentukan filter properti sederhana tambahan.
|
Isi permintaan
Isi permintaan harus kosong.
Isi respons
Pesan respons untuk EarthEngineService.ListFeatures.
Jika berhasil, isi respons memuat data dengan struktur berikut:
| Representasi JSON |
{
"type": string,
"features": [
{
object (Feature)
}
],
"nextPageToken": string
} |
| Kolom |
type |
string
Selalu berisi string konstan "FeatureCollection", yang menandainya sebagai objek FeatureCollection GeoJSON.
|
features[] |
object (Feature)
Daftar fitur yang cocok dengan kueri, sebagai daftar objek fitur GeoJSON (lihat RFC 7946) yang berisi string "Feature" di kolom bernama "type", geometri di kolom bernama "geometry", dan properti kunci/nilai di kolom bernama "properties".
|
nextPageToken |
string
Token untuk mengambil halaman hasil berikutnya. Teruskan nilai ini di kolom ListFeaturesRequest.page_token dalam panggilan berikutnya ke metode assets.listFeatures untuk mengambil halaman hasil berikutnya.

This method allows the caller to apply spatiotemporal and property filters to a table. Results are returned as a list of GeoJSON feature objects.\n\n### HTTP request\n\n`GET https://earthengine.googleapis.com/v1beta/{asset=projects/*/assets/**}:listFeatures`\n\nThe URL uses [gRPC Transcoding](https://google.aip.dev/127) syntax.\n\n### Path parameters\n\n| Parameters ||\n|---------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `asset` | `string` Required. The name of the table asset to list. `asset` is of the format \"projects/\\*/assets/\\*\\*\" (e.g., \"projects/earthengine-legacy/assets/users/\\[USER\\]/\\[ASSET\\]\"). All user-owned assets are 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\"). Authorization requires the following [IAM](https://cloud.google.com/iam/docs/) permission on the specified resource `asset`: - `earthengine.assets.get` |\n\n### Query parameters\n\n| Parameters ||\n|-------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `pageSize` | `integer` The maximum number of results per page. The server may return fewer assets 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 [ListFeaturesResponse.next_page_token](/earth-engine/reference/rest/v1beta/projects.assets/listFeatures#body.ListFeaturesResponse.FIELDS.next_page_token) returned from the previous call to the `assets.listFeatures` method. |\n| `region` | `string` If present, a geometry defining a query region, specified as a GeoJSON geometry string (see RFC 7946). |\n| `filter` | `string` If present, specifies additional simple property filters. |\n\n### Request body\n\nThe request body must be empty.\n\n### Response body\n\nResponse message for EarthEngineService.ListFeatures.\n\nIf successful, the response body contains data with the following structure:\n\n| JSON representation |\n|-------------------------------------------------------------------------------------------------------------------------------|\n| ``` { \"type\": string, \"features\": [ { object (/earth-engine/reference/rest/v1beta/Feature) } ], \"nextPageToken\": string } ``` |\n\n| Fields ||\n|-----------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `type` | `string` Always contains the constant string \"FeatureCollection\", marking this as a GeoJSON FeatureCollection object. |\n| `features[]` | `object (`[Feature](/earth-engine/reference/rest/v1beta/Feature)`)` The list of features matching the query, as a list of GeoJSON feature objects (see RFC 7946) containing the string \"Feature\" in a field named \"type\", the geometry in a field named \"geometry\", and key/value properties in a field named \"properties\". |\n| `nextPageToken` | `string` A token to retrieve the next page of results. Pass this value in the [ListFeaturesRequest.page_token](/earth-engine/reference/rest/v1beta/projects.assets/listFeatures#body.QUERY_PARAMETERS.page_token) field in the subsequent call to the `assets.listFeatures` 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)."]]
