  1. UTILITY GIS WORKSHOP APRIL 4, 2001 SPONSORED BY SEMCOG

  2. TODAYS AGENDA • SO YOU WANT TO BUILD A UTILITY GIS ? • LET’S SEE WHAT WORKS (and what does not) • WHAT ARE YOU GOING TO DO WITH THE UTILITY GIS ?

  3. PILOT DEFINITION • PURPOSE OF PILOT • CAD Conversion Techniques • Source Maps • Attribute Sources • Field Data Collection • JIM MILLER, OHM • Reasons To Conduct A Pilot

  4. REASONS FOR HAVING A PILOT • Financial evaluation • Procedural evaluation • Logistical evaluation • Political approval • Others?

  5. FINANCIAL EVALUATION • Representative area should prove or disprove that the budget is appropriate. • Production rates should give some indication if schedule is appropriate. • Will unforeseen tasks fit within the approved budget?

  6. PROCEDURAL EVALUATION • Is the consultants work plan going to get the job done? • Are all the steps accounted for? • Now is the time to make changes! Or else “Damn the torpedoes…”

  7. LOGISTICAL EVALUATION • Are all the source materials really available? What’s Plan B? • Does the consultant really have all the appropriate staff and resources to do the job? • Is the community really able to do their part?

  8. POLITICAL APPROVAL • Pilot should provide a quick turn around product for political buy-in. • Pilot should create enthusiasm and credibility for the “Champion” • Provides opportunity for scope and budget change in a positive context.

  9. OTHER GOALS? • Focus on communication issues. • Any hidden agenda?

  10. PILOT

  11. DEFINE DATA SOURCES • EXISTING DATA FILES • AS BUILTS • CAD DRAWINGS • FIELD SURVEYS • OTHERS

  12. DEFINE DATABASE • TRADITIONAL DATA MODEL • EXISTING DATA MODEL • UNIQUE DATA MODEL • FIELDS / FORMATS • LINKS TO APPLICATIONS

  13. OBJECT DATA MODEL • ESRI ArcFM Data Model • White Paper April 2000 • Hands On Implementation ? • Anyone ??

  14. CONDUCT PILOT • DEFINE PILOT GOALS • Pilot will establish costs, QC/QA procedures, data constraints, graphic and data maintenance functions • Examine several conversion approaches • paper to digital via heads up • field GPS with batch processing • Pilot review is key - everyone must be involved

  15. GPS CONVERSION

  16. CONVERSION EXAMPLE

  17. ATTRIBUTE COLLECTION

  18. REVIEW PILOT • CHECK PROCEDURES • FINALIZE QA/QC • ESTABLISH FULL CONVERSION COSTS • CAN WE AFFORD THIS ?

  19. DATA REVIEW

  20. FULL CONVERSION

  21. BREAK
