CGIA developed this set of point locations for public schools in North Carolina as part of a project for the NC Division of Emergency Management. School data serves multiple purposes, but foremost for this project, public schools are vital facilities in terms of emergency management. Many schools serve as shelters and all are critical to hazard vulnerability planning and emergency response. CGIA used two methods to generate point locations for public schools. First, CGIA used a road network from GDT, Inc. with ArcView GIS to geocode the addresses. This process matched 60 percent of the schools with a point on the road network. Point locations are approximate, based on an interpolation of street numbers along street segments. Second, CGIA worked with the NC Department of Public Instruction to use the Transportation Information Management System (TIMS) along with geographic layers from the NC Corporate Geographic Database to determine school locations. Many of these point locations are coincident with the center of school buildings on digital imagery or along driveways and may be more accurate than points located using the first method.
This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).

The attributes were loaded into the GIS from data supplied by the NC Dept. of Public Instruction. Minimal QC was performed during the digitization process on attributes. The values in the Dept. of Public Instruction data are reliable.
Using ESRI's ARC/INFO GIS software, the dataset was built for point topology using the "build" command. Topology has not been edited since the last build or clean.
The data represents those public schools which were either address matched using ArcView geocoding or matched manullay use the best available techniques. This data does not contain all the public school locations in North Carolina.
The majority of school locations were generated using geocoding in Arcview. The point generated in the processing would be snapped to the road identified in the address field. Therefore, point locations are coincident with the GDT roads data.
Locations of Schools by address
Point locations were generated using geocoding in Arcview. The resulting file was checked to determine which addresses did not match. These schools were located using the NC Department of Public Instruction Transportation Information Management System data. These locations were then added to the school coverage interactively, using GDT roads, Digital Raster Graphics and Digital Orthophoto Quarter Quadrangles as backcovers.
