Overview Sensor Web Enablement

Sensor Web Enablement (SWE) is an open standard framework of Open Geospatial Consortium (OGC) for exploiting Web-connected sensor and all-types of sensor system. The models, encodings, and services of the SWE architecture enable implementation of interoperable and scalable service-oriented networks of heterogeneous sensor systems and client applications.

The goal of SWE is to enable all type of internet-accessible sensor, service on sensor to be accessible, controlled via web service. SWE focused on developing standard to enable the discovery, exchange and processing of sensor observations, as well as the tasking of sensor system. Main function of SWE are:

  • Discovery and real-time observe sensor system
  • Determine sensor information
  • Access and configure sensor parameters.
  • Subscript and publish alert.

SWM

SWE use eXtensible Markup Language (XML) schemas to publish formal description of the sensor capabilities, location… then client, broker and server can parse and interpret the XML data, enabling automated web-based discovery of the existence of sensors and evaluation of sensor characteristics bases of published information. Information in the XML schema about a sensor’s control interface enable automated communication with the sensor system for various purpose.

Within the SWE initiative, data exchange is encoded by several standard interface definition for web services. Depend demand, we will choose specific encoding and service:
