| Abstract: |
"The State of Rhode Island Enhanced 911 Uniform Emergency Telephone System (RI-911), with the assistance of microDATA GIS, has recently completed an eight-year data development project to map each E911 address site, and create accurate geocoded street centerlines with actual address range and street name attributes, for every city and town in the state. Development of these layers is an important milestone for public safety in Rhode Island, and greatly improves the ability to locate 9-1-1 callers quickly and accurately during an emergency. These layers have also proven useful for additional GIS applications by other state agencies and municipalities. We will provide an overview of the data development project, the use of an ArcView extension for GPS field data collection, an ArcGIS extension for GIS data maintenance, multi-user versioned editing in an Enterprise ArcSDE geodatabase, ArcSDE 1-way replication for distributing GIS data updates, and an ArcEditor map display for RI-911 call-takers to locate 9-1-1 callers. This presentation will provide useful tips for ArcGIS users who are interested in developing and maintaining address point and street centerline data for your city or town, using these Rhode Island E-911 data layers in your own GIS applications, or how GIS data improves public safety in Rhode Island. |
