2.4 Using Services

2.4.2 Searching for a Service

To search for available services, click on the  symbol on the left hand menu of the explorer tab. This will give a list of all of the services that the user has access to, both their own or those that have been shared by other users, as shown below.

Services are processes that can be run on selected data, as described below There are also services which represent toolboxes that can be run on the data; these behave slightly differently and are described in section 2.7.

2.4.2 Running a Service

To run a service, click on the chosen service in the menu.

This brings up the workspace for the service, showing the  input parameters required for the service.

The input parameters required will vary from service to service, but there are some common features:

  • Processors can be run in two modes: standard or systematic. Most users will just require standard processing I.e. processing of one or more products in a single processing run. For advanced users, systematic processing is described in section 2.6.
  • Input data products (e.g. a sentinel-2 tile in the example above) can be dragged and dropped from the search results menu using the = symbol. Instead of single tiles, users can add multiple tiles or a databasket, in order to process multiple products in parallel. (See also section 2.4.)
  • Some processors are configured to work as parallel processors, generating subjobs as required (even if only one input).
  • Some services require additional reference data, which can be either uploaded by the user or else searched for as described in section 2.2.3.
  • Each job should be given a label to allow it to be identified.

Once all input fields have been completed the job is started by pressing on the arrow. The user will then see a message like this:

Pressing “Confirm” will cause the job to start and the users coin balance to be debited by the amount stated. The progress of the job can then be monitored as described in section 2.5.

If a user does not have sufficient coin balance then the job will be rejected. See section 6.2 for more details and how to request coins.

Note that where multiple (N) products have been input, the number of coins required will be N times the costs of a single product.
