GetCapabilities (SPS)

In order to work with a SPS, first you need information about this service. This includes, for example, which sensors are connected to a SPS, the location of the sensors, which measure (Phenomenon) are delivered by the individual sensors and the parameters that can or have to be set on a sensor so that a task can be processed.

This information is obtained by sending a GetCapabilities request to the service. In this case this can be a GET- or a POST-request.
