Abstract: The US Geological Survey-National Mapping Division created the 1:24,000-scale Pipe and Transmission data for their published maps. The NC Center for Geographic Information and Analysis, developed the NC statewide Transportation- Miscellaneous (1:24,000) digital data as a base layer showing pipe and transmission lines. This data was compiled directly from the DLGs. Apparent inconsistencies in specific areas may be due to different compliation dates of the source maps. Airports and landing strips have been removed and are stored in another file.
Purpose: DLG's depict information about geographic features on or near the surface of the Earth, terrain, and political and administrative units. These data were collected as part of the National Mapping Program. NC CGIA digitizes and distributes dlgs to help agencies and others make resource management and other types of decisions.
Supplemental Information: Refer to "USGS Digital Cartographic Data Standards," circular 895-G for USGS Coding Classification. system filename: mtt24 approx. file size = 0.9 mb Revisions and updates to this layer include: >1.) filename: mtt24_1298 This data was previously stored in >24 k quadrangle files. CGIA combined the available 24 k >files for North Carolina to enable easier use and distribution >of this information. This was the first release of this data in >a statewide format.
