Presentation Transcript

  1. GIS at NSOE Challenges Successes Areas for improvement

  2. GIS – Not your average application Falls somewhere between an operating system and a standard application File management Mapping interface

  3. Extensions, Tools, Toolbars, Models, Scripts…

  4. Large Datasets (often >100 Mb) National Land Cover Dataset – 30m Pixels

  5. Multiple file formats • Shapefiles (stored as 3 or more individual files) • Coverages (stored as a directory) • Raster images(tif, gif, img,…) • Personal geodatabases (MS Access files) • File geodatabases (stored as directory) • Spatial databases(SQL Server, Oracle,…) • Networked databases(ODBC, SOAP, REST)

  6. Volatile software • ArcGIS 8.x 1999 • ArcGIS 9.0 2004 • ArcGIS 9.1 2005 • ArcGIS 9.2 2007 • 4 service packs • ArcGIS 9.3 2008 • 1st service pack soon These are for the main application only, not for the extensions…

  7. GIS – an IT challenge • Complex application suite • Licensing requirements • Highly customizable interface • Often involves accessing large files • Multiple file types • Volatile software

  8. OIT/Nicholas IT successes • Complex application suite • Licensing requirements • Highly customizable interface • Often involves accessing large files • Multiple file types • Volatile software

  9. Needs work… • Complex application suite • Licensing requirements • Highly customizable interface • Often involves accessing large files • Multiple file types • Volatile software

  10. Student survey N = 15

  11. Areas for improvement • Network throughput to NSOE • Timing of computer changes (not just before classes begin…) • Response time to issues
