Road Centerlines / Address Points

Our office primarily focuses on accurate road centerlines and address points used in the local 9-1-1 centers. Spatial and internal (attribute) road and address data are crucial in locating both landline and wireless 9-1-1 calls. We assist the local PSAPs in creating, mapping, and maintaining accurate road centerlines and address points. We provide quality control services by testing the accuracy of road centerlines and address points, detecting errors, and fixing the errors to create more accurate data. We also offer training to the local 9-1-1 officials so they can maintain their own data.
