4. Basic Requirements for Sensor Web
Quickly discover sensors and sensor data (secure or public) that can meet my needs – location, observables, quality, ability to task
Obtain sensor information in a standard encoding that is understandable by me and my software
Readily access sensor observations in a common manner, and in a form specific to my needs
Task sensors, when possible, to meet my specific needs
Subscribe to and receive alerts when a sensor measures a particular phenomenon

7. Observations
Observation - an event whose result is an estimate of the value of some property of a feature-of-interest, obtained using a specified procedure
Observations are modeled as Features within the context of the General Feature Model - ISO 19109

8. SWE Components – Web Services
Access Sensor Description and Data
Command and Task Sensor Systems
SOS
SPS
Discover Services, Sensors, Providers, Data
Accessible from various types of clients from PDAs and Cell Phones to high end Workstations
SAS
Catalog Service
Dispatch Sensor Alerts to registered Users
Clients
SWE web services:
Sensor Observation Service – Access to sensor or simulated data
Sensor Planning Service – Sensor System or Simulator Control Interface
Sensor Alert Service – Subscribe to specific alerts usually derived from sensor/simulator data
Catalog Service – Discover other services, sensors, providers and data sets
SWE Steps:
Services are first registered in one or several catalogs also accessible through a standard interface.
Client can discover services, provider, sensors and datasets by using the catalog
Client can then access data from SOS, control sensors and simulators using SPS and receive alerts from SAS
