RFA has a GIS staff with over 30 years of combined experience in constructing, mapping, and maintaining map layers specific to 911 needs. Our mapping services are primarily focused on road centerlines and address structures, however, we offer general technical support specific to 911 for numerous counties around the state. General technical support may include:
- Creating, printing, and providing guidance in the creation of maps
- GPS support – mapping new roads for counties without proper GPS equipment
- 911 dispatch technical support including uploading new or updated map layers into the 911 mapping system
- Training of local 911 officials on the maintenance of road centerlines and address structure files
- Creation of map books to be used by local 911 officials
The mapping and addressing team collects 911 road centerline data from all 46 counties and merges these files into a statewide 911 file for use by other sections of RFA (Health and Demographics, Precinct Demographics, and Geodetic Survey) as well as other state agencies such as, DHEC, SLED, EMD, and the Forestry Commission.
Our office primarily focuses on accurate road centerline data used in the local 911 centers. Spatial and internal (attribute) road data is crucial in locating both landline and wireless 911 calls. We assist the local PSAPs in creating, mapping, and maintaining accurate road centerline data for use in dispatch. We provide quality control services by testing the accuracy of road centerlines, detecting errors, and fixing the errors to create a more accurate road file. We also offer training to the local 911 officials so they can maintain their own data.
Address Structures (Points)
Next Generation 911 is upon us and with that comes an emphasis on increasingly accurate GIS data for use in dispatch centers. Address structures are becoming a vital layer for dispatch mapping systems. Our office offers the same assistance with address structures as we do for road centerline data.
