DescribeSensor Response

The response to a DescribeSensor request is a Sensor Model Language (SensorML) document shown in your browser. This document describes the sensor system. [OGC 06-009r6, p. 26]

  • DescribeSensor response for a network - contains the description, search keywords, identifiers, classifiers, temporal validity, relevant contacts about this specific network, and a list of stations of this network including station ID, station name, identification, documentation, location
  • DescribeSensor response for a station - contains the description, search keywords, identifiers, classifiers, temporal validity, relevant contacts about this specific station, and list of observed properties at station including relevant component (sensor) information
  • DescribeSensor response for a sensor - contains the sensor identification, and location information.
