Description: The SUP_Fac_Point feature class includes polyline data on existing and proposed facilities such as crossing treatments for shared use paths, greenways, and trails. It also includes signage, access points and amenities for shared use facilities. The dataset provides a consistent set of attribute fields on existing and proposed shared use path facilities for use in planning, project development, and analysis. This data set was compiled from local bicycle and pedestrian plans supported by the NCDOT Planning Grant Initiative (initiatied 2004) and voluntary submissions from local jurisdictions from a solicitation process starting in early 2013. The data set remains incomplete as solicitation from agencies and jurisdictions within North Carolina is ongoing.

Description: The IPUMS National Historical Geographic Information System (NHGIS) provides free online access to summary statistics and GIS files for U.S. censuses and other nationwide surveys from 1790 through the present. NHGIS boundary files are derived primarily from the U.S. Census Bureau's TIGER/Line files with numerous additions to represent historical (1790-1980) boundaries that do not appear in TIGER/Line files. For more recent boundary files (1990 or later), NHGIS typically makes only a few key changes to the TIGER/Line source: (1) we merge files that are available only for individual states or counties to produce new nationwide or statewide files, (2) we project the data into Esri's USA Contiguous Albers Equal Area Conic Projected Coordinate System, (3) add a GISJOIN attribute field, which supplies standard identifiers that correspond to the GISJOIN identifiers in NHGIS data tables, (4) we rename files to use the NHGIS naming style and geographic-level codes, (5) we add NHGIS-specific metadata, and (6) most substantially, we erase coastal water areas to produce polygons that terminate at the U.S. coasts and Great Lakes shores.NHGIS derived this shapefile from the U.S. Census Bureau's 2020 TIGER/Line Shapefiles.
