公告:所有在
2025 年 4 月 15 日之前注册使用 Earth Engine 的非商业项目都必须
验证是否符合非商业性质的资格条件,才能继续使用 Earth Engine。
Method: projects.classifier.export
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
启动一个批处理流程,用于计算分类器并将其保存为 Earth Engine 资产。
HTTP 请求
POST https://earthengine.googleapis.com/v1beta/{project=projects/*}/classifier:export
网址采用 gRPC 转码语法。
路径参数
参数 |
project |
string
必需。应被视为此请求的服务使用方的 Google Cloud Platform 项目的项目 ID 或项目编号。格式为 projects/{project-id} 。
必须对指定的资源 project 具有以下 IAM 权限才能进行授权:
earthengine.exports.create
|
请求正文
请求正文中包含结构如下的数据:
JSON 表示法 |
{
"expression": {
object (Expression )
},
"description": string,
"requestId": string,
"assetExportOptions": {
object (ClassifierAssetExportOptions )
},
"workloadTag": string,
"priority": integer
} |
字段 |
expression |
object (Expression )
必需。一个表达式,其计算结果为要计算和导出的 Earth Engine 分类器。
|
description |
string
可选。任务的可选直观易懂的名称。
|
requestId |
string
可选。用于检测重复请求的唯一字符串。如果同一用户发出多个包含相同非空 requestId 的请求,则其中只有一个请求可以成功启动长时间运行的操作。requestId 可以包含字符 a..z、A..Z、0-9 或“-”。requestId 的长度不得超过 60 个字符。
|
assetExportOptions |
object (ClassifierAssetExportOptions )
必需。将导出内容配置为 Earth Engine 资产。
|
workloadTag |
string
可选。用户提供的用于跟踪此计算的标签。
|
priority |
integer
可选。项目中导出任务的优先级。系统会更早地安排优先级较高的任务。必须是介于 0 到 9999 之间的整数。如果未设置,则默认为 100。
|
响应正文
如果成功,则响应正文包含一个 Operation
实例。

ClassifierAssetExportOptions
将表保存为 Earth Engine 资产的选项。
JSON 表示法 |
{
// Union field destination can be only one of the following:
"earthEngineDestination": {
