The document provides an overview of the Open Geospatial Consortium's (OGC) Sensor Web Enablement (SWE) initiative, which aims to develop open standards for accessing sensor data on the web. The SWE framework includes standards for describing sensors, observations, and processes. It also includes web service interfaces for discovering sensors, retrieving observations, tasking sensors for new observations, and subscribing to sensor alerts. The goal is to make sensors accessible and controllable on the web through open standards in order to support a variety of applications.
