Air Quality Data Systems and the GEOSS Architecture
Rudolf B. Husar, Washington University
Given at the OGC Technical Committee MeetingSt. Louis, MO, March 24, 2006
Expanding on Presentations by
Doug Nebert, March 2008, ESIP Web Services. George Percivall, February 2008, ADC-6-Report
GEOSS ArchitectureDescribes how components fit together for providing data and information that will be better …than the individual components or systems of which it is composed.
Links together strategies and systems to facilitate Earth observations in a comprehensive, coordinated, and sustained manner.
By 2015, GEOSS will be a distributed system of systems, building step-by-step on current cooperation efforts among existing observing and processing systems within their mandates, while encouraging and accommodating new components.

AIP Process improvement ideas
Comments on AIP Process Process Improvement
Functionality defined by developers not users
UIC/ADC collab., Workshops;
Operational SBA functionality
AIP Process is closed Make development iterative; Anyone can join at anytime
Process focused on demonstrations
More operational persistence; Deliver AR-07-01 Operations
Too structured: milestones, deliverables
Retain structure within phase; More iterative, open approach
