Purpose​

The export service is responsible for packaging mapping data that can be downloaded by clients or transferred to other systems. Export can be requested for various mapping products within a specific region. The export module exposes an API and Web-based tool.

Usage​

You can create export tasks via the Export-Management service API.

warning

Authentication must be integrated in order to communicate with export service.
See the principles here

The API currently consists of two method:

  1. POST /export-tasks - Create a new export task. If the requested task params were previously created, they are returned in the response, otherwise they will be returned via the provided webhook.
  2. GET /export-tasks/{id} - Gets an existing export task data.
