Summary: Emergency Services Polygons and Road Centerline data in the WI NG911 GIS Data Standards schema.  This schema is nearly identical to the NENA NG911 Standard.  This data is managed by the Wisconsin Office of Emergency Communications (OEC)Purpose: The purpose of this data is to be used for Next Generation 911 i3 IP based emergency call routing via a NG911 ESInet.  The main purpose in making it available to the public is to enhance interoperability between emergency response agencies across the state of Wisconsin and beyond.  However, its contents and attribution may have many other applications.Source: This data is sourced from all 72 counties across the state of Wisconsin as well as the City of Milwaukee.Contents: Emergency Services Polygons and Road Centerline data in the WI NG911 GIS Data Standards schema.  This schema is nearly identical to the NENA NG911 Standard.  This data contains emergency services area polygons and road centerline data sourced from counties across Wisconsin during the Wisconsin Next Generation 911 Project. The emergency services polygon layers include all required polygon layers under the WI NG911 GIS Data Standards and NENA NG911 GIS Standards, including Data Provisioning boundaries, Public Safety Answering Point boundaries, Fire, Law, ane Emergency Medical Services boundaries  The data has been found to be critical error free by a QA process managed by the OEC via GeoComm's GIS Data Hub.  This data is currently incomplete as not all data providers have submitted data to the project at this time, or that data that has been submitted was not found to be critical error free.Update Cycle: This data is updated on a roughly weekly basis by the OEC.
