Method: projects.locations.tables.create

  • The tables.create method generates an ID representing a table based on a provided expression and output options.

  • This generated ID is then used with GetTableFeatures to retrieve the complete table data.

  • This two-part process offers more flexibility than ComputeFeatures, particularly in data retrieval and authorization methods for fetching table data.

  • The tables.create method is accessed via a POST request to https://earthengine.googleapis.com/v1alpha/{parent=projects/*/locations/*}/tables and requires specific OAuth scopes for authorization.

Creates an ID that can be used to render "table" data.

This is used in conjunction with GetTableFeatures. 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 GetTableFeatures 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 GetTableFeatures. 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.
