LIST OF OPERATIONS
In order to be in conformity with Article 11(1)(c) of Directive 2007/2/EC, the Download Service shall at least provide the operations listed in Table 1 of this Annex.
Table 1
Operation Role Get Download Service Metadata Provides all necessary information about the service, the available Spatial Data Sets, and describes the service capabilities. Get Spatial Data Set The Get Spatial Data Set operation allows the retrieval of a Spatial Data Set. Describe Spatial Data Set This operation returns the description of all the types of Spatial Objects contained in the Spatial Data Set. Link Download Service Allows the declaration, by a Public Authority or a Third Party, of the availability of a Download Service for downloading Spatial Data Sets or, where practicable, Spatial Objects, through the Member State’s Download Service while maintaining the downloading capability at the Public Authority or the Third Party location. The request and response parameters of each operation complete the description of each operation and form an integral part of the Download Service’s technical specifications.
