    • Transportation for the Nation

  • Ohio’s Initiative

    • Location Based Response System

What is nsgic

What is NSGIC?

  • NSGIC is an organization committed to efficient and effective government through the adoption of geospatial or mapping information technologies.

  • NSGIC members are actively involved in the coordination and application of mapping technologies in their States, the creation and management of mapping data as well as information technology policy

  • Membership - senior state geographic information system (GIS) managers and coordinators, representatives from federal agencies, local government, the private sector, academia and other professional organizations.

What nsgic does

What NSGIC Does

  • Provide a unified State voice on geographic information and technology issues,

  • Strong advocate for State interests,

  • Support back to the membership through national initiatives with statewide impacts

  • NSGIC promotes mapping information integration and systems development and provides input and advice to public and private decision-makers on national issues impacting the States.

    NSGIC advocates the benefits of mapping technologies and data that can only be realized through intergovernmental and private sector cooperation, coordination, collaboration and partnerships.

50 state gis coordinators reps

50 State GIS Coordinators/Reps

  • State Reps have a partnership role to play with geospatial data development programs

  • Many Member States have transportation initiatives

  • Interaction with Geospatial Coordinating Council or Body

  • Coordinators can assist in:

    • Contacts with other GIS Professionals

    • Coordinate Stakeholder community

    • Coordinate Data Resources and initiatives

    • Coordinated Funding Requests

    • Facilitated forums for Discussion


Transportation for the nation wg

Transportation for the Nation WG

  • Work Group’s focus is on the GIS representation of the nation’s transportation networks, focusing first on the street network – all roads – since it is the single most used, attributed GIS data set across the nation

  • Resulting in attributed street network for cartography, online mapping, address geocoding, and routing for more informed decision making and better investments.

  • Co-Chairs - Frank Winters (NY) and Dan Widner (Va)



  • Coordinated approach to street network data is imperative and supports the development of a nation-wide dataset, comprised of the best available data

  • NSGIC’s interest in transportation data is twofold:

    • 1) usefulness of transportation data goes beyond transportation applications.

    • 2) a nation-wide approach to transportation networks is important because we are increasingly working on problems that do not stop at municipal, county, or even state borders.

      A seamless transportation networks, with addressable roads as a first priority. Enable data sharing and value-added products to flow back down from each successive higher level of government

Work group s purpose

Work Group’s Purpose

  • Engage and enable Transportation Stakeholders to create local, regional, statewide, inter-state, and national transportation databases, feeding up from municipal and county governments with the best available infrastructure data.

  • Provide a grounding in transportation business language and state transportation programs for state geospatial coordinators.

  • Develop a plan for nation-wide to support each state’s Spatial Data Infrastructure (SDI) and the National Spatial Data Infrastructure (NSDI).

GIS-T – State Transportation Contacts


  • Engage qualified external stakeholders and invite participation.

  • Hold individual discussions with potential stakeholders including, but not limited to:

  • Host/schedule meetings/conference calls with stakeholders

  • Survey states to understanding of the range of options to develop and maintain statewide transportation databases.

  • Draft a plan for review by stakeholders.

Primary goal – identify and engage necessary stakeholders to move a national strategy for transportation forward - not set standards for Transportation/roads

Locating information by address in ohio

Locating information by Address in Ohio

  • Inconsistent Addressing information

  • Too many standards to choose from?

  • Everyone and their brother can assign addresses

  • No central authority

  • No clear maintenance responsibilities

  • Confidence and reliability w/results vary greatly

  • Legacy addressing databases


ZIP Code is not granular enough

Location based response system lbrs

Location Based Response System (LBRS)

  • Statewide high resolution road centerline coverage

  • Address ranges and site specific address

    • Higher confidence/increase reliability for geocoding

    • Known accuracy – understanding limits of data and use

  • Partnership with local government – not data grab!

    • Memorandums of Agreement (MOAs)

    • Integration of state and local government databases

    • Updated and Maintained

  • In a nutshell….One set of geography - Multiple attributes for different uses at all levels of government

    A new and better way of doing business

Local government impacts

Local Government Impacts

“There is no question - with the installation of this mapping system, and the ability to immediately employ our LBRS project, the emergency service to our community is going to be significantly enhanced.”

Kim Hambel, Communications Supervisor Muskingum County Communications Center

“We can now accurately locate and track cellular calls. This move towards tracking cellular calls was a necessary step to improve the safety of our communities.”

William Ommert, Huron County EMA Coordinator

Federal government impacts

Federal Government Impacts

“The LBRS files that we've used so far for TIGER realignment have been some of the best files that we've worked with ... the quality is definitely there. … we might have the opportunity to go back and use local [LBRS] centerline files that weren't originally used for the TIGER realigning process... If this happens… it would be a good opportunity to get the positional accuracy of LBRS files… into TIGER.”

Gordon Rector, Geographer US Census Bureau Detroit Regional Office

State government impacts

State Government Impacts

  • Tie robust ODOT attribute database to all roads

  • Package State data beneficial to Local Government in with program (tied to data model)

  • Create Partnerships - Push funding to Local Government to support the maintenance of spatial data and attributes

  • Provide a higher confidence in spatially enabled locations

  • State and Regional Coverages for Analysis Purposes

    • Better Protection of our citizens

    • Better Response to Local Government Needs

    • Better Use of Taxpayer Dollars

Lbrs summary

LBRS Summary

  • Is more than just a Roadway Inventory

  • Establishes a partnership between state and local government through a Memorandum of Agreement (MOA)

  • Recognizes the value local government brings to location based services

  • Represents a better way of doing business

  • Coordinates Maintenance at the Local Level to support activities at the State and Federal level

  • Improves Services & Emergency Response at all levels of government

Communication is key stay engaged and in touch

Communication is Key – stay engaged and in touch!

Work with NSGIC

Identify and communicate with your NSGIC State Rep

Build a stakeholder group in your state

Coordinate and work with your State’s Coordinating Body

Partnership is mutually beneficial and critical to the success of spatial data development

Communication and Coordination lead to Cooperation and Collaboration

Working Together for a Better Tomorrow

  • Nation’s transportation industry is a collection of industries and highly decentralized

  • The following numbers illustrate the degree of decentralization:

    • 39,000 governmental units own highways in the United States

    • 6,000 agencies operate transit services

    • Tens of thousands of private companies provide services to transport agencies

    • There are thousands of private trucking firms
