OWS-4 Scenario: Alert-driven Processing of Sensor OWS-4 Scenario: Alert-driven Processing of Sensor DataData

• Seek to automate and shorten the decision-action loop.

• Focus on:– automated sensor

management and sensor data processing to produce actionable information for decision makers.

SWE Service Model (A Data Center View) SWE Service Model (A Data Center View)

• SWE Services– SOS = Sensor Observation Service– SAS = Sensor Alert Service– SPS = Sensor Planning Service– CSW = Catalog Service (for Sensor

Resources)

• SWE Data Center– Composition of integrated SOS, SPS

and SAS service implementations – Tasking of sensors, access to sensor

system observation data and alerting of sensor system state changes and measurements.

– Support the requirements for sensor systems and protocols (IEEE1451, MPEG4, ANSI 42.42, XMPP, OASIS CAP/EDXML)

– Descriptions of the sensors systems, observation offerings and services must be published to CSW implementations

EO-1 User StoryEO-1 User Story

• DHS analyst requests satellite imagery in disaster area to validate potential site. Catalog returns EO-1 as possible source.[via CSW service].

• Access to high resolution EO-1 data is granted based on user/role permission

• No data is available, so satellite tasking is required and achieved (at no cost to DHS) [via SPS service].

• Analyst is notified via IM that Hyperion/ALI data products are available. High resolution imagery is retrieved [via SOS and WCS and WFS services].
