  1. Westchester County GIS Overview Westchester County Municipal Administrators Association Luncheon November 14, 2001

  2. Topics for Discussion: • Some GIS Terms & Concepts • Current Projects and Issues • Questions and Answers

  3. Many GIS Projects: “Are started with little planning, little design, and great expectations”

  4. GIS Integrates Data Video GPS Satellite Photos GIS Aerial Photos Multi- Media Geographic Data RDBMS Business Data Cable

  5. Municipal GIS Applications: • Internet Mapping • Infrastructure Management • Emergency Services & Dispatching • Tax Mapping & Land Records • Environmental & Land Use Planning • Economic Development • Health & Human Services • Pavement & Bridge Management Systems • Schools, Libraries, and Public Access

  6. Benefits of GIS: • Improved information management • Increased information analysis potential • Data centrally located and avoids duplication • Extensive cost efficiencies – once systems are built • Increased data access for decision making • Increased access to information • Provide public access to government information

  7. 5 GIS Major Components • Hardware • Software • Data • Applications & Routines • People

  8. Types of GIS Products • On-line data access and analysis • Presentation & draft quality maps; slide shows • Tabular reports & print outs • Export files for electronic distribution • Make information available for the internet

  9. Major Costs Associated with GIS Implementation: • Data Development, Conversion & Maintenance (75%-80%) • Staffing (full-time GIS/technical support) • Consulting -Application Development/Programming -General; all areas of GIS • Hardware & Software (w/maintenance) • Operations/Materials & misc. support

  13. County Base Mapping Project

  14. Primary Project Objectives: • Identify common base mapping needs for government, utilities, and business & professional organizations • Review administrative and administrative issues (FOIL, staffing, data distribution) • Review cost sharing options • Create Uniform, County-wide Digital Base Map

  15. Some Technical Specifications: • 2,200 countywide tiles • Color digital orthophotography • 1” = 100’ land base • 5’ contours • 35 features to be captured, including edge of payment, building footprints, normal planimetrics • Consistent with NYC database design • Seamless county-wide coverages • Municipal data “bundles” a deliverable in ArcView shapefile format

  16. At the direction of the County Executive, all County GIS data sharing requests and distribution policies are currently suspended and under review as a result of the events of September 11, 2001

  17. Pitfalls of a GIS • Overstating benefits • Failure to define goals • No long-term & strategic plan • Lack of management or technical support • Lack of user involvement/user training • Budget overrun (budget underestimation) • Hard to expand or modify existing/legacy systems

  18. GIS Myths: • GIS turns bad data into good data • GIS software has a “Just Do It” command • “You can save that in WORD format, right?” • GIS is a desktop publishing program • GIS can present everything on 8x11 paper in B/W • Staff don’t require training & education (No time!) • We’re going to make a lot of money selling this data! • That map can be scanned, right? • Buy just one copy & put it on every machine • Why are we replacing GIS with GPS? • “I can do this with MapQuest & MapBlaster, so…..”

  19. The IT Future Will Favor Spatial Data Investments That: • Multi-purpose • Maintained (updated) • Simple (minimum structure) • Integrated across disciplines • Standard Models • Documented (metadata) • Shared/Open

  20. Change Management: “Experience has shown that even the best technology strategies stand little chance of success if the workforce doesn’t accept and adopt them”
