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 has been in actively working since May 2014 to document core business needs among the partners. Hennepin County staff has provided project management, coordination and continuity to the collaborative.

  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 needs that this data model/dataset are intended to satisfy include:

  • Vehicular routing;
  • Address geocoding (the model will contain both assigned and theoretical ranges);
  • Next Generation 911 call routing and location validation;
  • Emergency services dispatching;
  • Support of linear referencing system use;
  • Cartographic representation of road features;

 MRCC Dataset Release Date:    April 21, 2017  

The MRCC partners are proud to announce the release of the first version of the MRCC road centerline dataset on April 21, 2017. The dataset is available here on the Minnesota Geospatial Commons site.

The Metropolitan Council, at the request of the Seven Metropolitan Counties, is preparing a data aggregation and validation solution to facilitate monthly centerline data updates.

 MRCC Proposed Version 1.6 

The MRCC project team members after publishing and testing Version 1.5+ are assessing the potential of a Version 1.6 of the MRCC Standard. This revision removes Theoretical Ranges from the schema and expands several domains.

The decision to move forward with the Version 1.6 schema will be discussed on September 28, 2017.
