  2. Introduction • Historical Overview of SF GIS • CCSF Enterprise GIS Initiatives • Spatial data distribution • Past data distribution policies • Current data distribution policies • Licensing Revenues • Legal Conformance • Long-term distribution objectives • Summary and Questions Department of Telecommunications & Information Services

  3. Historical Overview • CCSF has a fairly decentralized city/county model • Spatial data developed in multiple departments independently • DPW takes lead in basemap development (1994) • City departments individually use basemap in their own applications: pay yearly subscription fee for access • Interaction between departments is minimal • November 2000: Mayor makes announcement for DTIS to implement Enterprise GIS initiative. Department of Telecommunications & Information Services

  4. Enterprise GIS efforts • One primary Citywide data integrator, distributor, and entperprise application developer • Development of a dynamic, distributed spatial data warehouse • Implementation of web-enabled applications • Examination of data distribution policies • Design of appropriate citywide organizational model • Bring departments together (on multiple levels) Department of Telecommunications & Information Services

  6. San Francisco’s GIS Basemap • Primary objective was • to create a common GIS Basemap for City government to use and; • to build additional GIS layers and applications. • Basemap development took roughly four years to develop. • +/- 2.5 foot accuracy. • available in three file formats: AutoCAD, ArcInfo, and ArcView; as well as TIF and MrSID image formats. • Basemap layers are maintained and updated by DPW staff, and now distributed citywide by DTIS. • DTIS is providing Enterprise GIS services for all of CCSF Department of Telecommunications & Information Services

  8. Spatial Data Distribution Department of Telecommunications & Information Services

  9. Previous Distribution Policy • Basemap Data Layers were available to public directly from Department of Public Works (DPW) • DPW staff processed each request, each licensing agreement, each CD, etc. for both internal and external customers • Result of above efforts: • DPW staff resources were not available for core duties • At that time, DPW/CCSF was unable to appropriately market data • DPW sought outside help to handle external requests Department of Telecommunications & Information Services

  10. Current Distribution Policy • Basemap data layers available to public via our Value-Added Resellers • Barclay Mapworks, Inc. • Hammon, Jensen, Wallen & Associates, Inc. • ValueCAD, Inc. • City signed agreements with each VAR in 1998 • City receives percentage of gross licensing revenues, capped at a maximum amount • City receives royalties on all basemap-derived products sold Department of Telecommunications & Information Services

  11. Licensing Revenues • City receives revenue from each VAR on quarterly basis, if any • Through the VAR program: • ~ $30,000 collected since 1998 • Through direct licensing by the City: over $110,000 collected since 1996 (if staff costs are subtracted, total net would be less …) • Current revenue supplements, but clearly does not supports GIS Basemap and Library operating revenues • City able to finance new orthophotography Department of Telecommunications & Information Services

  12. Public Records ActConformance • CCSF has its own public records legislature • Sunshine Ordinance • Basemap system was granted an exception to the Sunshine Ordinance • Multiple CA govt. agencies dealing with • privacy • precedence in records act conformance • Electronic Media - AB2799 Department of Telecommunications & Information Services

  13. Long-term distribution objectives • Re-evaluate current VAR policy • Possible alternatives: • Full distribution of spatial data over the web (fits with CCSF Enterprise GIS model) • Hybridization of VAR/free distribution approach • Indirect benefits of full, free distribution seem to outweigh fiscal benefits with current VAR model • Bottom line: a new method of distribution needs to be implemented, which better encourages the use of spatial data (internal to CCSF as well as to the public) Department of Telecommunications & Information Services
