Centerline Collaborative


The Metro Regional Centerline Collaborative (MRCC) is a joint collaborative project involving the technical and managerial GIS staff from the Seven Metropolitan Counties (Anoka, Carver, Dakota, Hennepin, Ramsey, Scott and Washington), the Metropolitan Emergency Services Board and the Metropolitan Council to develop a road centerline data model and dataset to meet the core business needs of local governments and regional interests.

The MRCC officially kicked off in May 2014 to document core business needs among the partners. Hennepin County staff has provided project management in parternship with staff from the Metropolitan Council providing coordination and research to the collaborative. From 2014 to present, the MRCC project team has developed and enhanced several iterations of its road centerline standard to meet the various needs of the data producer and user community.

  Goal of the Project                  

The goal of the MRCC is to facilitate the creation and sustained maintenance of an authoritatively (locally) sourced road centerline dataset that can be used to meet the needs of local, regional and state partner agencies.  Over the course of 2014, the MRCC has documented the specific business needs of the participating partners and developed a draft data model to meet those expressed needs.

  Need for Project                     

At present, there is no authoritatively-sourced, inter-jurisdictional, publicly-available road data solution that meets the core business needs of 
local, regional and state agencies.  This project represents an effort to develop and sustain this much needed geospatial data resource.

  What are the core uses of this dataset?  

The core business needs and use cases that this data standard and dataset are intended to satisfy include:

  • Vehicular routing;
  • Address geocoding;
  • Next Generation 911 call routing and location validation;
  • Emergency services dispatching;
  • Provision for the future support and usage of linear referencing system data;
  • Cartographic representation of road features;

‚Äč  Progress Update: February 2019 Update  

As In spring 2018, the State 9-1-1 Work Group took the MRCC standards and re-tooled it into a candidate for a statewide road centerline standard. This new statewide standard (called the MRCS - MN Road Centerline Standard) has been through one statewide stakeholder reivew (April - June 2018) and will be out for review until March 19, 2019.

Downloads & Resources

 MRCC Road Centerline Data   Availability and Versioning  

The MRCC partners published the first version of the MRCC April 21, 2017. The most current version of the MRCC dataset is available here on the Minnesota Geospatial Commons site.

The Metropolitan Council, at the request of the Seven Metropolitan Counties, has prepared a validation and aggregation solution to facilitate frequent MRCC data updates. The most current version will be available from the Commons with updated metadata; please refer to the metadata which accompanies the dataset.

 MRCC Version 1.7 

The MRCC project team members have advanced a Version 1.7 of the MRCC dataset. This version aligns with the Minnesota Address Point Data Standard (adopted on December 6, 2017 by the Geospatial Advisory Council) and the specific needs of NextGen9-1-1.

The MRCC Version 1.7 is currently 'frozen' (e.g. no additional changes or revisions made), until such time the MRCC Build Team or Core Team see fit to revise the schema.
