  1. Interactive Displays of Air Quality Information:Status of the Ozone Plume in Maryland and the Mid-Atlantic Duc NguyenMichael WoodmanDavid KraskPresented at:2009 National Air Quality ConferencesAddison, TXMarch 5, 2009

  2. Authors are not Responsible for Accuracy of Non-Maryland Data.In Addition, Data SHOULD ONLY be USED for Outreach, Educational, and Analysis! Before We Start … WARNING

  3. Outline • Project Overview • What Was Learned • Live DEMO

  4. Project Overview • Estimate the Areal Extent of the Ozone Nonattainment in Maryland and Mid-Atlantic. • Demonstrate the Sustained Reduction in Ground-Level Ozone Since 1990. • Make Data Easily Understandable for the General Public, Legislators, and Others Interested in Tracking Ground-Level Ozone Pollution. OBJECTIVES

  6. What Was Learned … • Google Earth / Virtual Globe has become Extremely popular due to its developmental approach (User User interaction). • Being utilized by everyone: private sectors, commerce, media, non-profit organizations, government agencies, universities, etc. • BAD & GOOD: Contents in Google Earth are SATURATED! Let Someone else create the “Bad” contents! CHALLENGE

  7. Resourcesfor Creating Google Earth Contents • GPSVisualizer: Online software developed by Adam Schneider to generate maps and Keyhole Markup Language (KML) files. Thus far, this is probably the best resource ever developed, which fully exploits the power of Google (map API, Google Earth, KML, etc.), environmental data (satellite data), and other interesting items. • GEGraph: Stand-alone freeware written by Dr. Ricardo Sgrillo to generate 2D or 3D graphs in the form of a KML file. • Additional software packages that will work with ArcMap: Shape2Earth and KMLer. • Text editors for viewing and editing KML files: PSPad (free) and UltraEdit ($50). • Other tools: Excel, Access, Other Spreadsheet software, Illustrator, etc.

  19. Lindenworld~15 miles SE of Philadelphia, PA. 2002 2003 2004 2005 2006 2007 Slight over-interpolation persists through the years. Magnitude varies depending on raw data.

  20. 30 miles SE of Knoxville, TN 2002 2003 2004 2005 2006 2007 Slight over-interpolation persists through the years. Magnitude varies depending on raw data.

  21. Toledo, OH Prior to 2003 1991 1990 1992 1993 Some under-interpolation persists prior to 1994. Areas of under-interpolation shrink over time, probably due to more data coverage.

  22. Maine in 2003 Over interpolation due to low data coverage
