  1. ONLINE GAP DATA EXPLORER TOOL:An Open Source GIS Decision Support Tool for Gap Analysis Data Steven G. Williams, James B. White Biodiversity and Spatial Information Center NC Cooperative Fish & Wildlife Research Unit North Carolina State University 11 September 2007 Asheville, NC

  2. Standard GAP Data Distribution • 500+ data layers • 2+ CD set Big, Serious GIS Data • Difficult to access

  3. Built around the RTNCF Ecosystem GAP Dataset • Displays data quickly and easily • Based on a full-featured installation of ArcView 3.2 with Spatial Analyst • Allows for a wide array of skill levels

  4. RTNCF Dataset Rationale for moving to web-delivered Decision Support Tool • Requirements: • Expensive proprietary software required • Data set is static and dispersed • 365 raster data layers • 3+ gigabits of data

  5. Rationale for moving to web-delivered Decision Support Tool • 420 raster data layers • 22+ gigabits of data NC State Dataset

  6. Rationale for moving to web-delivered Decision Support Tool • Requirements: • Browser and internet connection • Single, centralized data set • 800+ raster data layers • 300+ gigabits of data • Online analysis capabilities are a necessity for users without substantial GIS hardware/software capabilities SW Regional Dataset

  7. Main Map Frame Control Frame 3 tabs View Layers Define AOI Legends Inset Map Frame List Frame Tools Frame

  8. What’s Next… • Puerto Rico GAP Dataset • Session histories tied to logins… • Ability to save session to allow users to work on an analysis over time • Precompiled reports … • Large extent AOIs Lots of challenges!
