New STAC connection

The Create STAC Connection dialog box allows you to make a connection to a single STAC API. Once the connection is made, you can browse, filter, and select various catalogs, collections, and items within the STAC connection. Fill in the required information on the Create STAC Connection dialog box:

• Connection Name—Name of the STAC connection. This is saved in the Project folder as an .astac file.
• Connection—A list of predefined STAC connections. You can also add a custom STAC connection by providing the connection URL.
• STAC API Authentication (Optional)—Credentials to access private/protected STAC APIs (supports only OAuth 2.0 Azure authentication). See Connect to authentication providers from ArcGIS Pro for more information on how to set up OAuth authentication in ArcGIS Pro.
• Custom Headers (Optional)—Specify any additional headers to include in the request sent to the STAC server. For example, specify a raw bearer token, if the service is secured using custom OAuth.
• Custom Parameters(Optional)— Specify any additional parameters to include in the request sent to the STAC server. For example, specify a token, if the service is secured using token based authentication.
• Cloud Storage Connections (Optional)—Select one or many cloud storage connections to access data, based on the collections used.
  • Use the Add Cloud Storage Connection File option to add an existing cloud storage connection.

  • Click Delete to remove the cloud storage connection from the list.
