This comprehensive initiative presents a
vision of statewide data sharing in partnerships with county, municipal, state, and federal data providers. NC OneMap is not simply a viewer but a comprehensive program that promotes geographic data standards; data currency, maintenance, and accessibility; data documentation (i.e. metadata); and a statewide data inventory. The initial focus is on 37 priority data themes (e.g. orthophotography, roads, parcels, municipal boundaries, surface waters, land use, soils, public lands, watersheds, wetlands, police stations, etc.). The NC OneMap program promotes data cost-sharing at the local government level.
Protocols for bringing data content together from local, state, and federal sources with consistent standards are being explored, as well as infrastructure policies. A formal
implementation plan was adopted by the GICC in 2004 and forms the basis for budgetary requests to the North Carolina General Assembly. The NC OneMap Program is actively promoting
archival mechanisms so historic data sets are preserved for both temporal analysis and for the long term.
Geospatial Portal
Effective June 2011, statewide 2010 orthoimagery for North Carolina is now available online through the new
NC OneMap Geospatial Portal! Or visit the
NC OneMap website. The NC OneMap Geospatial Portal is the new evolving way to discover and access spatial resources for all of North Carolina. Keyword searches and searches by spatial extent will make it easy to find the content you seek in your area-of-interest. Visitors can also keep apprised of the latest updates by subscribing to the web feed.
Over the next several months the contents of the NC OneMap data download and web map services pages will migrate to the Geospatial Portal. For now, the Portal contains the public release of the 2010 statewide orthoimagery. More information on the 2010 statewide orthoimagery project is available
here.
NC OneMap Free Data Download
NC OneMap provides a free FTP site for download of more than 100 popular state data sets. In addition to vector data, the FTP offers free raster data of current and historic orthophotography from more than 87 local governments. Or you can browse the orthophotography through the
NC OneMap Ortho Server.
And, for users who want to download local government data, where allowed, NC OneMap provides a direct link to the available local government website. Visit the
NC OneMap website for more information.
Viewing North Carolina Data
Everyone with an Internet browser can view and use numerous data sets through the
NC OneMap viewer: no GIS software is necessary. Local government
partners allow numerous data sets (such as parcels, streets, zoning, jurisdictional boundaries, orthophotography, i.e. aerial photography) to be displayed through the web viewer. Local data is combined with state and federal data, in real time, as you zoom-in to a selected geographic area. The NC OneMap viewer is just one exciting feature of the NC OneMap program.
