  1. A GIS Atlas for Indiana:Recent Developments and Future Plans Indiana Geological Survey A collaborative project of: Indiana Geological Survey Indiana Department of Transportation Bernardin, Lochmueller and Associates, Inc. • John Steinmetz, Denver Harper, Chris Walls, • Chris Dintaman, Rick Hill, Kathy Griffin, Paul Irwin Bernardin, Lochmueller and Associates, Inc. • David Isley, Neal Schroeder, Cinda Bonds, Kia Gillette Indiana Department of Transportation • Janice Osadczuk, Mike Wood

  2. What is “A GIS Atlas for Indiana”? • A Web site that utilizes Internet Map Server (IMS) technology to provide an interactive map that can be accessed simultaneously by many people. • A central repository from which GIS data can be freely down- loaded. • An on-going project. Cody Walls, GIS dog

  3. Recent Improvements in Usability • New layers and updates • Redesign of interactive map • Technological enhancements • Customized tutorial Population Density 2000

  4. Usability: New layers and updates • Total layers = 210 • 50 new layers added in 2004 • Environmental layers • Census and demographic data • Legislative boundaries • Zip Code Areas, School Districts, and more • 19 layers updated or corrected • Environmental layers • Watershed boundaries • Aerial photos (DOQQs) Population Change 1990-2000

  5. Usability: Redesign of interactive map Vertical tool bar Subfolders Direct links to metadata and downloads On-line poll “Save/Restore” tools

  6. Usability: Technological enhancements Enhancements: • Upgrade to ArcIMS 9.0 • Conversion from shapefiles to SDE geodatabase • Adoption of dual spatial servers • Implementation of open-GIS Web Map Server (WMS) connector Benefits: • Increased speed and stability • More simultaneous users • Wider accessibility (NationalMap, AutoDesk, and others) Land cover

  7. Usability: Customized tutorial Second edition Revised 1/19/2005 • Available on CD-ROM • Available on-line

  8. The Importance of Feedback • Web usage • Direct contacts • Online poll Aerial photo 1998-99

  9. Feedback: Web usage User sessions in January, 2005 = 50,926 Unique users in January, 2005 = 17,828

  10. Feedback: Direct contacts Contacts by e-mail and phone • 2002 - 4 • 2003 - 39 • 2004 – 132 • Industry – 50 percent • Government – 25 percent • Academia, general public – 25 percent Crops 2002

  11. Feedback: Direct ContactsExamples of changes made in response to users’ suggestions • Added “Save/Restore” tool. • Added new layers such as ecoregions, floodplains, civil townships, and others. • Modified view scale and added auto labeling for watershed (HUC14) boundaries. • Changed symbol for bedrock contours. • Replaced corrupted DOQQs. • Removed sensitive layers for security reasons. HUC14 Watersheds

  12. Feedback: On-line poll • One vote per IP address • Votes from IGS excluded • Question 1: How would you rate the interactive map? (Total responses = 141) • Very useful = 116 (82%) • Somewhat useful = 15 (11%) • Not useful = 10 (7%) • Question 2: How would you rate the tutorial? (Total responses = 53) • Very helpful = 23 (43%) • Somewhat helpful = 6 (11%) • Not helpful = 3 (6%) • Not attempted = 21 (40%) Prime Farmland

  13. Plans for the Future • New layers coming soon: • Color aerial photographs (NAIP 2003) • Soils (NRCS SSURGO) • Floodplains (IDNR DFIRM) • Crops 2003 (USDA) • Indices to historical aerial photos • Benchmarks (NGS) • Increase interoperability: • More layers on NationalMap • Utilize large raster sets hosted by Indiana University UITS Color aerial photo 2003 (NAIP)
