Functions

The information division maintains, manages, and implements the information technology (IT) network for the office:  all databases pertaining to 9-1-1 Communications, as well as all Computer-aided Dispatch (CAD) systems that are relied upon by the 9-1-1 Communications Center, York County Sheriff’s Office, and other county departments and municipalities.  We also utilize Geographical Information Systems (GIS) technology to support the integrity of correct road placement data and provide accurate response information needed for dispatching police, fire, and medical personnel. 

Reponsibilities

• Manage the New World System’s CAD and CAD Mapping applications to ensure accurate information is used throughout the county for geographical verification and dispatch of emergency response agencies.
• Review and approve all new road names and subdivision names for development in York County to avoid road name duplication and eliminate any phonetically alike names in the same emergency response area.
