1 2006 GIS-T T Symposium Columbus Ohio Creating a Location Based Response System Using ESRI Technology Brian Stevens, CP Woolpert, Inc.

2 Agenda Introduction What is LBRS? History Specifications Proposed Method Case Study Highland County, OH Summary Questions and Answers

3 What is LBRS? Location Based Response System A multi-jurisdictional statewide asset database that ensures the quick and rapid response of emergency responders to natural and man made disasters. - OGRIP

4 LBRS History Created by OGRIP Financial Contributor Address Based Specifications Partnered by ODOT Quality Control Responsibilities 3D Segment Length and Log Point Computation Based Specifications 10 County Pilot Program Street Centerline Field Collection Process Address Point Field Verification

5 LBRS Specifications GPS Centerline Points Not Required if Using Photogrammetric or Base Mapping Method Address Points 1 Point for Every Address (Multi-point Properties) Related to Street Centerline Street Centerlines Constructed with Address and Log Point Direction in Mind Alternate Street Names Table Records Related to Street Centerlines by ID

6 Example LBRS Data

7 Photogrammetric / Base Mapping Method Does Not Require Total Field Address Verification County Determines the Percentage and Location of the Addresses to be Verified Allows for Data Creation Within a Single Environment ESRI Builds Upon Existing Datasets Base Mapping Digital Orthophotos Properties with Addresses (CAMA) Street Centerlines Accurate Surface Model Address Range Database Alternate Street Names Database

8 Case Study Highland Co., OH History Initiated a full ESRI based GIS in Aerial Base Mapping (2002) Blue-booked Monumentation Orthophotos Contours LiDAR / DTM Street Centerlines Hydrology - Parcel Mapping (2003) - CAUV Mapping and Application Development (2004)

9 Case Study Highland Co., OH con t County Facts 558 Square Miles Approximately 35,000 parcels Approximately 1200 Road Miles Properties Based on VMS Located in the Foothills of the Appalachian Mountains

10 Case Study Highland Co., OH con t LBRS Specifics 70% of the Addresses in the County Do Not Require Field Verification Parcels Joined with Current CAMA Information on a Weekly Basis County Provided a Maintained Address Range Database

11 Address Range Database

12 Address Range Assignment

13 Address Point Creation

14 3D Length and Log Point Generation Overlay Street Centerlines with an Accurate Surface Model (DTM) Determine the Origin Point of the Street Centerline Calculate a 3D Length (Mileage) Assign Mile Marker Values at Log Point Intersections Compare Calculated 3D Length Values with ODOT Supplied Values Flag Gross Inconsistencies For Further Investigation

15 QA/QC SmartMapper QC Enhanced Rules Based Quality Control Flexible Rule Creation Dynamic Error Reporting Error History Tracking

16 SmartMapper QC

17 What s Next? Review Current Address Assignment and Maintenance Process Design New Processes and Procedures Design and Develop Address Assignment and Maintenance Applications Educate County Staff in the Use of New Processes and Applications MAINTAIN ADDRESSES!

18 Summary Capitalizes on the Use of Existing Data Without the Need for Complete Field Verification Results are As or More Spatially Accurate than Alternative Methods Accurate Attribute Driven QA/QC Processes Potential Overall Time Savings Based on Data Availability and Completeness

19 Questions and Answers Thank You!
