  1. The Expanding Role of GIS in Business and GovernmentSpatial Data Infrastructure for Economic and Community DevelopmentRemarks byProf. Joseph Ferreira, Jr. MIT, jf@mit.edu

  2. Technology-driven Issues and Trends • How ‘place’ is recorded, • The usefulness of Administrative Records (AR), • Changes in metropolitan information infrastructure, • Implications for economic and community development Wharton Impact Conference, August 21, 2002

  3. How ‘place’ is recorded • Old Way (1:250,000 scale) • County, city, SMSA, census tract • Standardized, federal datasets (Census, USGS,…) • New Way (1:25,000 scale) • Census block and block-group, zip, Tiger • Geocoding addresses, Mapquest, GDT,… • Next Way (1:2,500 scale) • Parcel, person, building, feature • GPS location, Ankle braclet, Community asset,… Wharton Impact Conference, August 21, 2002

  4. Usefulness of Administrative Records • Traditional study strategy • Special surveys: census, activity report, phone survey,… • Customized, cross-sectional ‘snapshot’ • Administrative Record alternative • Transactional records: registry of deeds, building permit, DMV, housing court,… • Event-driven, hard-to-(re)use, voluminous Wharton Impact Conference, August 21, 2002

  5. Changes in Metro Information Infrastructure • Rapid growth of standardized, spatially disaggregated, georeferenced data • Progress in regional consistency (e.g., parcel data for metro Portland, OR, with consistent land use, zoning, valuation) • Progress in Federally-supported ‘framework datasets’ (State & NSDI efforts, Enviromapper) • Critical mass of networked, graphics/GIS capable workstations and Web servers Wharton Impact Conference, August 21, 2002

  6. Changes in Metro Information Infrastructure - BUT • Hard to cross-reference all the data • Many access/sharing/privacy issues • Data centers can’t keep up (too much data, too many updates) • E-government and Mapquest-like services are good but limited ‘automation’ efforts • Must shift from ‘data center’ to ‘web services’ infrastructure Wharton Impact Conference, August 21, 2002

  7. Chaining Web Services • Isolated Data Centers • Chained Web Services (virtual data centers) Wharton Impact Conference, August 21, 2002

  8. Implications for CSS • Virtual data centers (portals) can: • Tap administrative records more easily • provide cost-effective customized value-added • But, they require different expertise, sophistication, partnerships • And new methods for data access, privacy protection, cross-referencing, funding Wharton Impact Conference, August 21, 2002

  9. Next Steps and References • Organizational efforts and urban ‘testbeds’ • Next-Generation Community Statistical Systems conference: http://www.shimberg.ufl.edu/conference.html • Paper: “Information Technologies that Change Relationships between Low-Income Communities and the Public and Non-profit Agencies that Serve Them” http://web.mit.edu/sap/www/colloquium96/papers/7ferreira.html Wharton Impact Conference, August 21, 2002
