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.listAssets
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Mencantumkan aset penampung, seperti folder atau koleksi.
Permintaan HTTP
GET https://earthengine.googleapis.com/v1alpha/{parent=projects/*}:listAssets
URL menggunakan sintaksis gRPC Transcoding.
Parameter jalur
| Parameter |
parent |
string
Wajib. Nama aset penampung yang akan dicantumkan. parent memiliki format "projects/*" atau "projects/*/assets/**" (misalnya, "projects/[PROJECT]" atau "projects/earthengine-legacy/assets/users/[USER]/[ASSET]"). Semua aset milik pengguna saat ini berada dalam project "earthengine-legacy" (misalnya, "projects/earthengine-legacy/assets/users/foo/bar"). Semua aset lainnya berada dalam project "earthengine-public" (misalnya, "projects/earthengine-public/assets/LANDSAT"). Jika "projects/earthengine-legacy" ditentukan, respons akan terdiri dari daftar semua folder tingkat atas yang dimiliki oleh pengguna yang meminta.
Otorisasi memerlukan satu atau beberapa izin IAM berikut pada resource yang ditentukan parent:
earthengine.assets.getearthengine.assets.list
|
Parameter kueri
| Parameter |
pageSize |
integer
Jumlah maksimum hasil per halaman. Server mungkin menampilkan lebih sedikit aset daripada yang diminta. Jika tidak ditentukan, ukuran halaman default bergantung pada EarthEngineAssetView, dengan batas yang lebih tinggi untuk tampilan yang lebih ketat.
|
pageToken |
string
Token yang mengidentifikasi halaman hasil yang harus ditampilkan server. Biasanya ini adalah nilai ListAssetsResponse.next_page_token yang ditampilkan dari panggilan sebelumnya ke metode projects.listAssets.
|
filter |
string
Jika ada, menentukan filter. Filter hanya diterapkan ke aset ImageCollection dan diabaikan untuk aset Folder. Kolom startTime, endTime, dan anggota properties dikenali. Fungsi kustom intersects(str) tersedia, yang memungkinkan pemfilteran menurut geometri. Contoh filter tanggal:
"startTime>\"2020-01-01T00:00:00+00:00\" AND
endTime<\"2020-02-01T00:00:00+00:00\""
Contoh filter properti:
"properties.CLOUDY_PIXEL_PERCENTAGE<30"
Contoh filter geometri:
"intersects(\"{'type':'Point','coordinates':[1,2]}\")"
"intersects(\"{\\\"type\\\":\\\"Point\\\",\\\"coordinates\\\":[1,2]}\")"
Lihat https://google.aip.dev/160 untuk mengetahui detail selengkapnya tentang bahasa filter.
|
view |
enum (EarthEngineAssetView)
Menentukan bagian resource EarthEngineAsset mana yang akan ditampilkan dalam respons. Hanya berlaku untuk aset ImageCollection. Semua elemen aset Folder akan dienkode dalam tampilan BASIC, terlepas dari nilai kolom ini.
|
Isi permintaan
Isi permintaan harus kosong.
Isi respons
Jika berhasil, isi respons memuat instance ListAssetsResponse.
