About NC OneMap

NC OneMap is the geospatial data backbone supporting North Carolina data users. It is an organized effort of numerous partners throughout North Carolina, involving local, state, and federal government agencies, the private sector and academia. NC OneMap is an evolving initiative directed by the NC Geographic Information Coordinating Council.

The NC OneMap Program promotes and supports:

The NC OneMap Initiative
In 2003 the NC Geographic Information Coordinating Council (GICC) adopted this comprehensive initiative in partnership with county, municipal, state, and federal data providers. The NC OneMap Program promotes a vision for geospatial data standards; data currency, maintenance, and accessibility; data documentation (i.e. metadata); and a statewide GIS inventory. Thirty-seven priority data themes were selected as the initial focus.

Protocols for bringing data content together from local, state, and federal sources with consistent standards are being explored, as are infrastructure policies. A formal NC OneMap implementation plan was adopted by the GICC in 2003. It formed the basis for budgetary requests to the North Carolina General Assembly in 2007, and the subsequent development of the “State Geographic Information/Consolidation Implementation Plan” that was submitted to the General Assembly in December 2008. The “State Geographic Information/Consolidation Implementation Plan” was adopted as part of the FY09-10 budget bill in August 2009.

The NC OneMap Program is actively promoting archival mechanisms so historic data sets are preserved for both temporal analysis and for the long term.

NC OneMap Accountability Measures
In 2012, the NC OneMap Governance Committee adopted a set of performance accountability measures to evaluate the success in meeting four defined objectives for NC OneMap. To review the objectives, goals and measures, see here.

Benefits
State, local and federal government agencies, universities, K-12 schools, utilities, non-profit organizations and the general public all need a reliable statewide resource. NC OneMap provides that critical linkage that helps promote public safety, better government decisions, and economic vitality in our communities.

  • Access through one location to the most up-to-date geospatial data
  • Instant availability of multi-jurisdictional data
  • Data distribution costs lessened for participating governments
  • Public investment leveraged for maximum effect
  • More than one million dollars in cost-shares for local government orthoimagery
  • 2010 statewide orthoimagery funded by the NC 911 Board and available free through the NC OneMap Geospatial Portal
  • Focus on common data framework and standards
  • Forum for the NC GIS community to raise issues and solve problems together

CGIA and Program Implementation
CGIA is staff to the NC Geographic Information Coordinating Council (GICC). CGIA is responsible for executing GICC directives, including the NC OneMap implementation plan. The NC OneMap Geospatial Portal and the Data Explorer are hosted through CGIA, which provides the data server and technical support for partners. The North Carolina General Assembly created a Database Administrator position to manage the NC OneMap content and a second position, NC OneMap Application Developer, that supports the viewer and participant connections.

Staff administers the websites, metadata program, NC OneMap GIS Inventory, cost-share programs for local government orthoimagery, and federal grants in support of tasks specified in the Implementation Plan.

Preservation and Long-Term Access to Geospatial Data
The preservation of digital geospatial data content is a growing concern. Geospatial data are public records, many of which need to be preserved for their legal, fiscal, analytical and historic value. Critical information captured in geospatial datasets include aerial imagery, land records, transportation, regulatory data, demographics, governmental boundaries, and marine and natural resources.

The GICC has been involved in this effort through its vision for NC OneMap, which states that “historical and temporal data will be maintained and available.” Work is progressing on several fronts to build local and state government awareness about the need to archive and preserve data assets for the long term, and to provide the tools to assist in that effort. Achievements include guidance documents, projects to develop concepts and practices, and the NC OneMap Retention Schedule.

The GeoMapp project, funded by the Library of Congress, paired state government archives staff with geospatial experts to investigate the issues surrounding the preservation of “at risk” geospatial content. CGIA and NC State Archives led a four year, multi-state project to explore methods for preserving at-risk geospatial data. The partners included the states of Kentucky, Montana, North Carolina and Utah along with active participation from information partners in 14 other states who participated in project meetings. Library of Congress and National Records and Archives Administration staff were active participants in the effort. The project team investigated the policies, process, inventory, technical infrastructure, storage capacity, and funding issues involved in ensuring long-term access to data. The NC OneMap program is essential to the development of successful preservation strategies because it provides the technical and social interface, i.e., the organized data structure, for geospatial archiving.

Project Deliverables See the GeoMAPP website to read the interim and final reports documenting the interim processes, technical white papers and business planning tools.

State Archives of North Carolina provides access to a listing of the data through an online catalog called MARS, a database of archival holdings.  Users cannot download the data from MARS but a limited number of datasets can be downloaded from a tool called ContentDM.  Additional datasets will be available soon.  ContentDM was built for images but also enables access to other types of datasets online.  The metadata record is provided as an html file to enable users to assess whether a dataset meets their needs. PDF files enable users to access a snapshot and preview the dataset.
