AI-generated Key Takeaways
-
The
tables.createmethod generates an ID representing a table based on an expression and output options, intended for use withtables.getFeaturesto retrieve the table data. -
This two-part process of creating an ID and then fetching data is more flexible than
ComputeFeatures, particularly in terms of data retrieval and broader access using an API key. -
The HTTP request to create a table is a POST to
https://earthengine.googleapis.com/v1beta/{parent=projects/*}/tables, requiring a parent project and an optional workload tag in the query parameters. -
The request body should contain a
Tableinstance, and a successful response will return a newly createdTableinstance. -
Authorization requires one of the specified OAuth scopes.
Creates an ID that can be used to render "table" data.
This is used in conjunction with tables.getFeatures. A call to tables.create provides an expression and some output options. The result of tables.create is an ID that represents a table that is the result of evaluating that expression and applying those options. Subsequently, calls to tables.getFeatures can be made to get the table data for the entire resulting table. The ID will be valid for a moderate period (a few hours).
The most common use case for this pair of endpoints is to provide a complex expression via a POST to tables.create, and then fetch the computed table via a GET to tables.getFeatures. This two-part process allows for use in more situations than ComputeFeatures. In particular: - the result of ComputeFeatures requires pagination to get the entirety of the features. Additionally only individual Features are returned. - ComputeFeatures can only be called by an authorized user, using a properly-scoped OAuth token. tables.create has the same restriction, but GetTableData can be invoked with a URL containing an API key, so URLs invoking it can be used more broadly.
HTTP request
POST https://earthengine.googleapis.com/v1beta/{parent=projects/*}/tables
The URL uses gRPC Transcoding syntax.
Path parameters
| Parameters | |
|---|---|
parent |
Required. The parent of the location where the table will be created (e.g., "projects/*"). |
Query parameters
| Parameters | |
|---|---|
workloadTag |
User supplied tag to track this computation. |
Request body
The request body contains an instance of Table.
Response body
If successful, the response body contains a newly created instance of Table.
Authorization scopes
Requires one of the following OAuth scopes:
https://www.googleapis.com/auth/earthenginehttps://www.googleapis.com/auth/earthengine.readonlyhttps://www.googleapis.com/auth/cloud-platformhttps://www.googleapis.com/auth/cloud-platform.read-only
