Addressable Street Centerlines Dataset


How to obtain the dataset(s) top of page

See the Order Information to learn how to obtain NCompass ( formally The Lawrence Group) Addressable Street Centerlines .


Common information needs met by this dataset top of page

This dataset meets more than one of the MetroGIS community's common information needs. Click on the information needs below to learn more about them, or to find out more about common information needs in general, please see the About Information Needs page.


Enhancements to the original dataset top of page

MetroGIS's Business Information Needs Process calls for each regional custodian and MetroGIS to co-sponsor Data User Forums on a reoccurring basis for each endorsed regional dataset. The frequency of the forums is determined by MetroGIS. The purpose of these forums is to monitor user satisfaction and identify desired or needed enhancements to the regional data solutions, insuring they continue to address the needs of the MetroGIS community. The history of these forums for this dataset is as follows:


History of the original dataset top of page

In March 1996, MetroGIS staff approached The Lawrence Group (TLG) about the possibility of a public-private partnership that would make TLG's Street Centerline dataset available to the MetroGIS community. In a parallel initiative, the Minnesota Department of Transportation (MnDOT) had secured an independent evaluation of street centerline data options for the "Orion" Project. The results determined that TLG's product was the best available by a considerable margin. By mid-1997, the Metropolitan Council and MnDOT where able to formalize a partnership to license this data for public sector and academic interests. All of this activity occurred before MetroGIS had finalized its Business Information Needs process.

The MetroGIS Address Workgroup met on December 11, 1997. The Workgroup concluded addresses must be dealt with as ranges associated with street centerlines and as attributes of parcels. The street centerline component has been implemented for the "address for people, places, and things" information need. See the Parcel Boundaries Information Need for information about the parcel component of this information need.

On May 27, 1998, the Policy Board endorsed TLG's street centerline dataset as a primary source of address matching for MetroGIS. A public-private partnership between the Metropolitan Council, Mn/DOT, and TLG provides access to this dataset by all government organizations and four-year academic institutions that serve Minnesota. The Policy Board had previously endorsed a document entitled "Guidelines for Working with Address Data", developed by the MetroGIS Standards Advisory Team, for use by the MetroGIS stakeholder community. Use of these guidelines will ensure that the user can take full advantage of the address matching capabilities associated with the endorsed regional street centerline dataset.

The Governor of Minnesota recognized this solution as an Exemplary GIS Project in October 1998. See the Awards section of this site for more on the recognition.

In late 2004, a workgroup was established to investigate options for supporting a regional street centerline dataset that not only provided the functionality associated with the solution achieved through the use of The Lawrence Group's data but which also satisfied: 1) the needs of the Emergency Management (E911) community and 2) the desire to be incorporated into the Census Bureau's TIGER produces, in particular census geography. The timing of the creation of this workgroup was mainly in response to the U. S. Census Bureau's proposal to establish procedures by April 2006 to incorporate locally-produced data into the Bureau's TIGER products. Otherwise, the Bureau planned to develop their own data they need to satisfy their improved accuracy specifications. On April 20, 2005, the MetroGIS Policy Board endorsed an ambitious vision to achieve the desired outcomes. The actual vision statement, information about its development, and next step efforts to achieve it can be viewed at http://www.metrogis.org/info_needs/street_addresses/add_wkgp.shtml
