1 Rhode Island GIS Data Development Project Jonathan Hall microdata GIS, Inc.

2 Overview 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 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 GIS data development project, and our current GIS data maintenance efforts; which use an ArcGIS extension for GPS field collection, an ArcGIS extension for GIS data maintenance, and an ALI database management system. These applications which allow sychronizing the ALI/MSAG and GIS databases, and greatly improve the results of our call-takers GIS map display for locating callers. This presentation will provide useful tips for GIS users and professionals who are interested in developing and maintaining address point and street centerline data for your city, county, or state, and will describe how GIS data improves public safety in the State of Rhode Island.

7 Abstract of Site Data Originally developed by manually digitizing from 1:5000 scale spring 1997 photography. In December 2001, MicroDATA GIS and RI-911 began field-verifying all roads, road names, and sites; and adding sites using GPS. Year 1 of the project included field-verification in the municipalities of: Exeter, Glocester, and Tiverton. Year 2 of the project included field-verification in the municipalities of: South Kingstown, East Providence, North Providence (and Centerdale) Year 3 of the project included field-verification in the municipalities of: Newport, Middletown Year 4 of the project included field-verification in the municipalities of: Providence, West Warwick, Warwick Year 5 of the project included field-verification in the municipalities of: Cranston, Pawtucket, Narragansett, Woonsocket Central Falls and Westerly. Year 6 of the project included field verification in the municipalities of: Warren, North Kingstown, Bristol, Coventry, Jamestown, Barrington, Smithfield, Charlestown, Portsmouth, Cumberland, Johnston, North Smithfield, Hopkinton, Richmond Year 7 of the project included field verification in the municipalities of: East Greenwich, Scituate, Lincoln, Foster, New Shoreham, Burrillville, West Greenwich, and Little Compton. On a daily basis, verification data from the field was imported into the master data set, and checked by a GIS technician. As field-verification was completed in each municipality, an extensive set of automated and manual quality control audits were completed to verify attribute accuracy, to reconcile GIS data with telephone company MSAG and ALI data, as well as data from local officials, and to verify route connectivity. Geocoding was updated from the TIGER values to the actual address range of existing sites along each road segment, and audited to verify attribute accuracy. Assessment reports of site addressing, road geocoding, roads in the MSAG that were missing in the GIS, and roads in the GIS missing from the MSAG were provided by microdata GIS for evaluation by each municipality. After a period of municipal review, any final changes or corrections provided by local officials were completed, and GIS Sites data was published for use by RI-911.

8 Abstract of Street Data Originally developed and designed for Enhanced purposes only. This data set contains street center lines for all highways, roads, and streets for the entire state of Rhode Island dated 12/15/2005. MicroData GIS conflated road names and address ranges from the existing E911rds24k roads coverage to the E911rds5k roads coverage. Field verification, addition of new roads, and attribute enhancement has been completed in the towns of East Providence, Exeter, Glocester, North Providence, South Kingstown, and Tiverton and are incluced in this data set. Field work and anhancements for Middletown, Newport and Provdence are in progress and enhanced but unverified values are also included in the data set. This data was developed and designed primarily for use within the RI E911 program. Centerlines were originally developed by manually digitizing from 1:5000 scale spring of 1997 orthophotography, and were enhanced in the cities and towns specifically menetioned above using data captured using vehicle-mounted GPS. RDS was originally developed using road centerlines from RIGIS & RIDOT (RIGIS-CAT-ID = s44trd97), which had been manually digitized from 1:5000 scale spring 1997 photography. In 2001, Road name, address range, route number, and functional class attributes were conflated by MicroDATA GIS for RI-911from 1:24,000 scale U.S. Census TIGER line roads, that had been enhanced by RIGIS & RIDOT. These road centerlines were audited by MicroDATA GIS to verify attribute accuracy, and route connectivity. Beginning in November 2001, proof plots were provided by RI-911 to the E-911 coordinator for each municipality, and checked for road name accuracy. A listing of road names in the telephone company Master Street Address Guide (MSAG) that were missing in the GIS was provided with the proof plot. Where possible, missing roads from the MSAG listing were identified by the municipality from unnamed roads in the GIS. If possible, an approximate location was compiled on the proof plot by the municipality for the remaining missing MSAG roads. These new roads were digitized by MicroDATA GIS, with locations approximated from the proof plots, digital 1:5000 scale orthophotos, or other maps and data provided by the municpality. In December 2001, MicroDATA GIS and RI-911 began field-verifying all roads, road names, and sites; and adding new roads or sites using GPS. Year 1 of the project included field-verification in the municipalities of: Exeter, Glocester, and Tiverton. Year 2 of the project included field-verification in the municipalities of: South Kingstown, East Providence, North Providence (and Centerdale) Year 3 of the project included field-verification in the municipalities of: Newport, Middletown Year 4 of the project included field-verification in the municipalities of: Providence, West Warwick, Warwick Year 5 of the project included field-verification in the municipalities of: Cranston, Pawtucket, Narragansett, Woonsocket On a daily basis, verification data from the field was imported into the master data set, and checked by a GIS technician. As field-verification was completed in each municipality, an extensive set of automated and manual quality control audits were completed to verify attribute accuracy, to reconcile GIS data with telephone company MSAG and ALI data, as well as data from local officials, and to verify route connectivity. Geocoding was updated from the TIGER values to the actual address range of existing sites along each road segment, and audited to verify attribute accuracy. Assessment reports of site addressing, road geocoding, roads in the MSAG that were missing in the GIS, and roads in the GIS missing from the MSAG were provided by MicroDATA GIS for evaluation by each municipality. After a period of municipal review, any final changes or corrections provided by local officials were completed, and GIS roads data was published for use by RI-911.

25 2008 Data Development Completed: June 30, 2008 Roads and Sites field-verified by GPS in every city & town GIS road names synchronized with MSAG in every city & town ALI database records matched to GIS Sites in every city & town Roads and Sites certified by municipal review Call takers now have a complete, state-wide dataset

26 Pictometry Obtained Homeland Security Grant funding New state-wide, high-resolution, color aerial photography, was flown in the Spring of inch pixels Oblique images, as well as Orthogonal images we can see every structure, every street, every lake, every pond, the ocean, whatever exists on earth, at various angles, so we can actually measure, for example, how high a house might be, how far away the nearest hydrant is or, if there were a hostage situation, we can tell the local authorities where to put the command center.

27 2009 GIS Data Maintenance Status On-site contractor, A. K. Associates, using ArcGIS 9.3 and x9gis extension Updating GIS data with newly constructed Streets and Sites, built since the initial field verification Synchronizing GIS street names with MSAG changes Synchronizing GIS site addresses with ALI changes
