  4. Centerline Data Issues • Roads Extending Beyond or Stopping Short of County Boundary • Topological Errors (Overlapping & Intersecting Road Segments, Dangles) • County vs. City Ownership • Out-of-Date Centerlines • Bad Centerline Geometry • Inaccurate Attribution • Erroneously Coded Roads • Unresolved “Public” and “Unknown” Roads

  5. Out-of-Date Centerline The Centennial Olympic Park Vicinity

  7. Where Are We? • As of June 28, 2013 • 120 Complete • 39 In Progress

  8. How Can You Help? • Provide Digital (GIS) Street, Boundary and Parcel Data • Share Street Attribute Data • Identify Road Ownership • Resolve Boundary Road Issues • Be Available To OTD For Consultations Via Phone, E-Mail or Meetings • Work With OTD and Neighboring Agencies To Resolve Conflicts
