  1. Air Quality Data Systems and the GEOSS Architecture Rudolf B. Husar, Washington University Given at the OGC Technical Committee Meeting St. Louis, MO, March 24, 2006 Expanding on Presentations by Doug Nebert, March 2008, ESIP Web Services. George Percivall, February 2008, ADC-6-Report

  2. GEOSS 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. GEOSS Architecture Describes 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.

  8. Updates for each step Architecture Documentation Baseline AI Pilot Development Approach From Percivall, Feb 2008 Participation AR-07-02 Architecture Implementation Pilot Evolutionary Development Process Concept Development Participation Call for Participation Participation Kick-off Workshop Participation Development Activities Participation Persistent Operations (AR-07-01) Operational Baseline for next evolutionary spiral

  9. Adopted from Percivall, Feb 2008 by R. Husar AIP Process improvement ideas Comments on AIP Process Process Improvement Air Quality CoP Approach UIC/ADC collab., Workshops; Operational SBA functionality Functionality defined by developers not users Contact with UIC; Toronto, Workshop; Open Invitations, ESIP, CoP wiki Make development iterative; Anyone can join at anytime AIP Process is closed More operational persistence; Deliver AR-07-01 Operations Process focused on demonstrations Expand AQ Data Netw; Seek link to AR-07-01 Retain structure within phase; More iterative, open approach One phase at a time; Feedback, feedback Too structured: milestones, deliverables
