The problem is, these questions can be far from clear. Cell phones don\u2019t always convey an accurate location and street addresses don\u2019t always match the map.\r\n\r\n\u201cA fire department deputy chief told me they regularly get calls from fire crews they send into a neighborhood where all the streets at one intersection have the same name,\u201d said Peter Schoenfield, GIS analyst, Lake County, Illinois. \u201cThe dispatcher might say \u2018Turn left on Lake Shore Drive,\u2019 but they\u2019re all Lake Shore Drive.\u201d\r\n\r\nThat scenario is typical of how addresses can become barriers to accurate wayfinding. In the US, local authorities maintain addresses and update shared maps using a geographic information system (GIS). Data is then shared with 911 call centers, known as public-safety answering points (PSAPs).\r\n\r\nIn Illinois, officials are working to solve this problem by undertaking a statewide modernization effort, Next Generation 911 (NG911), led by the Illinois State Police. NG911 will connect all 911 call centers and use GIS to increase address accuracy which will improve response times across the state. NG911 has been promoted at the national level, but it\u2019s up to each state to tackle the move to internet-protocol hardware and associated enhancements.\r\n\r\n\u201cThe old systems are antiquated, particularly the call-handling equipment that telecommunicators use at each PSAP,\u201d said Cindy Barbera-Brelle, statewide-911 administrator at the Illinois State Police. \u201cWe\u2019re getting to the point where 911 Systems have to look for parts on eBay, because the equipment is that old.\u201d"},{"acf_fc_layout":"image","image":404472,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"Modernization will unlock entirely new capabilities to better communicate the nature and location of each call for help.\r\n\r\n\u201cYou can text and send pictures and videos to friends and family, but you can\u2019t to 911,\u201d Barbera-Brelle said. \u201cWe\u2019re really in a new environment where technology is advancing far more quickly than it ever has. Catching up to what consumers can do with their cell phones has been a driving force behind NG911.\u201d\r\n<h3><strong>Moving to Geospatial Routing in Illinois<\/strong><\/h3>\r\nModernization will also replace the standard Master Street Address Guide\u2014a tabular database with address ranges that ties a phone number to an address. When it was introduced decades ago, the guide was a great leap forward. It became so reliable that 911 telecommunicators could first ask landline callers, \u2018What is your emergency?\u2019 because the location was already known. Now that most phones are mobile, telecommunicators have had to go back to also asking, \u2018Where is your emergency?\u2019\r\n\r\nIllinois will answer that time-consuming and often confusing question by moving to geospatial routing and delivery of 911 calls. The new solution will automate turn-by-turn directions, using critical details in the GIS to improve location accuracy.\r\n\r\n\u201cNowadays, the vast majority of calls coming into 911 centers are from cell phones,\u201d Schoenfield said. \u201cWe\u2019ve been building our data sets to be able to pick up the X-Y coordinate of that cell phone, drop it on a map, and pick out who the closest responders are. With NG911, a call won\u2019t even get to the dispatch center until it\u2019s been touched in some way by a GIS.\u201d"},{"acf_fc_layout":"image","image":404422,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"Each PSAP uses GIS to record key layers of data that include boundaries of fire, EMS, and police response jurisdictions, street centerlines, and address points. GIS also records provisioning boundaries\u2014coverage exceptions that get worked out between neighboring responders. \u201cI\u2019ll cover this, even though we share it,\u201d Barbera-Brelle explained.\r\n\r\nIn addition, GIS includes many capabilities to accurately record and verify a location, represent it on a map, share address information, pinpoint a position, and direct responders to where they are needed. The use of GIS paves the way to include z-axis (vertical) support for call routing within buildings to specific floors or units.\r\n\r\nTo make the move to geospatial routing, boundaries and address data must be accurate and synchronized between PSAPs in order to assign the right responders and route them to the right location.\r\n\r\n\u201cFrom the beginning, I knew that GIS would be at the center of deploying the statewide NG911 System that I was tasked with,\u201d Barbera-Brelle said.\r\n<h3><strong>Helping Each Other Achieve a Rapid Response<\/strong><\/h3>\r\nThe legislation that put the Illinois State Police in charge of statewide NG911 includes all 911 Systems in 102 counties across the state. Chicago, which is going through its own modernization effort, will connect to the statewide network. Barbera-Brelle will need to engage with 911 Systems in every county and get their data to carry out the ambitious plan.\r\n\r\nBecause funds generated for PSAPs are tied to land line, wireless, and Voice over IP customers, fewer land lines has meant less funding to modernize in rural areas. However, grant programs were created \u00a0to provide for NG911 readiness.\r\n\r\nTo start, much of the investment went to modernizing call-handling and recording equipment to meet\u00a0<a href=\"https:\/\/www.nena.org\/\">National Emergency Number Association<\/a>\u00a0(NENA) standards to deploy an Emergency Services IP network (<a href=\"https:\/\/www.nena.org\/page\/i3_Stage3\">ESInet<\/a>)\u2014a network of networks to connect all PSAPs. Funds have also gone to licenses and training for <a href=\"https:\/\/www.arcgis.com\/index.html\">ArcGIS Online<\/a>, Esri\u2019s software-as-a-service GIS offering, and fresh aerial imagery to help counties update their maps.\r\n\r\n\u201cSome counties still have rural addresses that need to be updated, and I know that work is very labor-intensive,\u201d Barbera-Brelle said. \u201cSo, we offered grant funding for GIS projects as well.\"\r\n\r\nAn additional effort involves the use of <a href=\"https:\/\/www.esri.com\/en-us\/arcgis\/products\/arcgis-hub\/overview\">ArcGIS Hub<\/a> to enhance mutual aid and collaboration. The Illinois State Police NexGen911 Data Hub establishes workflows for data input that walk users through each step. It increases the visibility of progress across the state with a status map that shows data submitted and data quality. GIS data maintainers and administrators can access the hub to ask each other questions and share expertise.\r\n\r\n\u201cOnce everybody submits their data, they need to work with neighbors to make sure boundaries and jurisdictions are not overlapping or gapping,\u201d Barbera-Brelle said. \u201cGIS allows them to see where any issues are. Then they can work it out, so we have consistency.\u201d"},{"acf_fc_layout":"sidebar","layout":"standard","image_reference":null,"image_reference_figure":"","spotlight_image":null,"section_title":"","spotlight_name":"","position":"Center","content":"<h2><strong>Updating the NG911 Address Data Model<\/strong><\/h2>\r\nThe foundation for strong address data lies in a data model within a geodatabase, to standardize what is collected and how the information is stored.\r\n\r\n\u201cWhen we first saw the NG911 specs, we realized immediately that that was going to require massive changes to our road centerline data sets and the address point data sets,\u201d said Peter Schoenfield, GIS analyst, Lake County, Illinois. \u201cWe wanted an updated data model that we could put our data into, but nobody had one.\u201d\r\n\r\nThe team set out to create this foundation, with some alignment to the work of the National Emergency Number Association, a key player in the move to NG911.

Soon, they formed a NG911 advisory board, and its members have been instrumental in setting standards, workflows, and checking data quality.\r\n\r\n\u201cWe took the initiative because as a statewide organization, we figured this is the perfect glove to put our hand into,\u201d said Creighton who was president of ILGISA when the effort began. \u201cIt brought the community together. We started with an exploratory effort to understand GIS capacity across the state. We then created a schedule for the required datasets.\u201d\r\n\r\nIn the beginning, Creighton was the primary data reviewer. Now, the GIS Center at Western Illinois University has taken a larger role for data quality checks. University students participate in the work, drawing pay and gaining practical knowledge.\r\n\r\n\u201cWe get data of varying degrees of quality,\u201d said Chad Sperry, director, Western Illinois University (WIU) GIS Center. \u201cWe've got validation and QA\/QC procedures in place that make sure that this data is standardized, it's scrubbed, and it's clean before it's ultimately uploaded to the state hub and centralized and merged. This is a really important project. We've got double-checks, and we review the data in multiple ways to make sure that we're not missing anything.\u201d\r\n\r\nIn the past, the smaller communities or GIS managers didn\u2019t have time or a strong need to prioritize data quality. \u201cIt's kind of a wake-up call for the GIS community,\u201d Schoenfield said. \u201cThe importance of our data has been elevated.\u201d\r\n\r\nNow, the need for data accuracy is clear to everyone involved in the NG911 project.\r\n\r\n\u201cIt\u2019s rewarding to hear first responders screaming for this data,\u201d Sperry said. \u201cThey realize they\u2019re doing a disservice to their people if they don\u2019t have good maps.\u201d\r\n\r\nThe WIU GIS Center also works more directly with 16 counties in its region that are thankful for mapping and data assistance, because they have a history of not getting a lot of help.\r\n\r\n\u201cIf you search on the word <a href=\"https:\/\/en.wikipedia.org\/wiki\/Forgottonia\">Forgottonia<\/a>, it brings up the west central Illinois region,\u201d Sperry said. \u201cIt was coined in the late 1960s in response to the lack of transportation funding and money coming from the state and federal government. I grew up on a farm in this area, so that\u2019s where my desire to serve it comes in.

In Lake County, one of Illinois\u2019 more populous regions with 700,000 people in the northeast corner of the state, ongoing issues prompted a large re-addressing effort.\r\n\r\n\u201cBack in the \u201970s, the county took all unincorporated addresses and standardized them,\u201d Schoenfield said. \u201cA handful of subdivisions complained, and the county acquiesced and let them keep their old address numbers, while maintaining 5-digit addresses for county government use. A few years ago, we realized this 'dual-addressing' was a problem that needed to be fixed so we crafted a new address ordinance that allowed those non-standard addresses to remain if they were logically consistent\u2014even on one side, odd on the other, with addressing flowing from low to high. When this couldn\u2019t be maintained, new addresses or even street names were issued to correct the problem.\u201d\r\n\r\nThe move was essential to create the consistency a computer can understand and that logically flows along a street, but it was far from trivial.\r\n\r\n\u201cIt was a major chore,\u201d Schoenfield said. \u201cWe had to meet with each homeowner\u2019s association. We had to send letters out to all of the different stakeholders, not just fire and police, but sheriff, and all the different utility companies, the county clerk, the treasurer. We also had to talk with the data supplier of delivery services like FedEx and UPS to make sure they got our changes as fast as possible. Anybody that had a stake in the address, we had to notify that the address was changing.\u201d\r\n\r\nFor delivery, the post office is the top priority.\r\n\r\n\u201cYou have to get the post office the right address or it's not going anywhere,\u201d Schoenfield said. \u201cWe send over a list, and then check it every month to make sure they are recorded correctly, if we have any fixes, we wait another month and check it again. It's a very involved process and you really have to have the fortitude before you embark on something like this.\u201d\r\n\r\nFor first responders, changes in address flow cause problems that Schoenfield and his team hear about often.\r\n\r\n\u201cEach fire district we consulted with would tell us about streets that were messed up,\u201d Schoenfield said. \u201cAddresses might start with three-digits in a municipality, but then when you get halfway down the street they jump. Crews that don\u2019t know the area, turn around thinking they missed the address without realizing they have to go another mile before the address system changes again.\u201d\r\n\r\nWhen time is critical, even momentary confusion can have dire consequences.\r\n\r\n\u201cFirst responders will tell you that two minutes is the difference between life and death,\u201d Schoenfield said. \u201cThat\u2019s why we need to make these changes.
