LBRS Overview• Managed by the Ohio Geographically Referenced Program
(OGRIP)• Establishes partnerships between State and County government
for the creation of spatially accurate street centerlines with address ranges and field verified site-specific address locations.
• Provides compliancy specifications• Data maintained at the local level• Intended to reduce redundant data collection efforts

Franklin County Project Overview
• Two Phases• Phase 1 – Centerline Development (approx 5,600 miles)
• Phase 2 – Address Point Verification (approx 650,000 points)
• Utilize existing datasets to support the LBRS data development
• Integrate datasets from multiple municipalities• Validate existing information for use in the LBRS
compliant database• Conduct field verification activities as required

Phase 1 - Street Centerlines
• Geometry• Alignment, Shape, Divides, Intersections, Coincident Geometries, Generalization and Densification
• County and Jurisdictional boundaries• Cul-De-Sacs
• Island – Loop around• No Island – End at Center
• Driveways, Parking Lots, Alleys• Metro Park Roads
![Page 11: Case Study: Franklin County, Ohio Location Based Response System (LBRS) Project Presented by: Transmap ® Corporation Ohio GIS Conference 2009.](https://reader035.fdocuments.in/reader035/viewer/2022062519/5697c0141a28abf838ccd18d/html5/thumbnails/11.jpg)
Phase 1 - Street Centerlines
• Topology• Dangles, Pseudo Nodes, Overlaps, Self-Overlaps• All segment ends are “Snapped”• Verify all dangles are street ends• Nodes
• A node at every at-grade intersection.• A node where a road name changes.• A node at the intersection of jurisdictional boundaries• Overpass/Underpass should have no segment ends/starts
![Page 12: Case Study: Franklin County, Ohio Location Based Response System (LBRS) Project Presented by: Transmap ® Corporation Ohio GIS Conference 2009.](https://reader035.fdocuments.in/reader035/viewer/2022062519/5697c0141a28abf838ccd18d/html5/thumbnails/12.jpg)
Phase 1 - Street Centerlines
• Other Centerline Geometry Checks• Coincident geometries• Offset Centerlines• Centerlines that do not accurately match curvatures of roadways• Centerline Orientation• Zero Length Geometry• Overpass/Underpass

Phase 2 - Address Points
• Assign unique Street Segment Identifier• Basis for building segment level address ranges• Identify points to be field verified
• Missing address point• Coincident and Duplicate address points• Missing or Incorrect address number• Missing or Incorrect address street name• Address point location• Address point with missing street centerline

Benefits of using existing data
• Data Collection / Data Development has already occurred
• No need to spend money recollecting good data
• Able to focus required field activities
• Overall project cost is lower than collecting all new data
![Page 18: Case Study: Franklin County, Ohio Location Based Response System (LBRS) Project Presented by: Transmap ® Corporation Ohio GIS Conference 2009.](https://reader035.fdocuments.in/reader035/viewer/2022062519/5697c0141a28abf838ccd18d/html5/thumbnails/18.jpg)
Challenges of using existing data
• Different data sources covering the same area
• Varying data quality
• Data currency issues
• Different database schemas
• Different domain and pick list values
![Page 19: Case Study: Franklin County, Ohio Location Based Response System (LBRS) Project Presented by: Transmap ® Corporation Ohio GIS Conference 2009.](https://reader035.fdocuments.in/reader035/viewer/2022062519/5697c0141a28abf838ccd18d/html5/thumbnails/19.jpg)
Summary
• Each County is different so the approach will depend on a variety of factors
• Total size of County
• Population Density
• Existing dataset accuracy and currency
• Participation from all stakeholder groups
• Existing datasets can be utilized as a foundation to meet LBRS specifications
• New field data collection/verification as needed
