GeoLynx Training

Twenty counties have now been trained to use GeoLynx for editing the SAM Address Points, submitting changes needed in the NYS Streets data, and downloading the updated data from the GeoLynx GIS Portal. GeoLynx training of additional counties is on hold while SAM Program Manager Cheryl Benjamin delivers the SAM Address Point data to the final handful of counties who have not yet received their data.


SAM Address Points and NYS Streets Edits

We have now passed the 1 year mark since we went live with GeoLynx WebDMS! Since March 2014, our data maintenance partners have made over 14,250 edits to the Address Points and entered over 1,600 Change Requests for Street and/or Address Point updates. In addition, the SAM Team has made over 154,000 edits to the NYS Streets and over 238,500 edits to the Address Points (many related to removing AP_Flags associated with new streets they added or errors they corrected in the NYS Streets).

Upcoming Changes to Data Distribution

In addition to the updated statewide NYS Streets file and the county cuts of the NYS Address Points that are posted nightly to our GeoLynx GIS Portal, county cuts of the NYS Streets file (in geodatabase and shapefile formats) are now available on the Portal. They are currently only updated Sunday evening due to the time the data packaging scripts take to run. Counties who are not yet GeoLynx users will have their existing FTP account holder assigned an account for the Portal so that they, too, have access to the most up-to-date data. New Portal account holders will receive GeoLynx GIS Portal training at one of several short webinars soon to be scheduled.

Coming Soon... Publically Accessible Parcel Data in GeoLynx

Since the last newsletter, the SAM Team has been testing incorporation of the GIS Program Office's publically accessible county parcel web service into GeoLynx. An Identify service limitation in our current version of GeoLynx is temporarily preventing us from adding the service at this time. We have a GeoLynx upgrade planned for early summer that should allow us to add the parcel service. In the meantime, check out the public web service! To date, parcel data for 12 counties has been made publically available. Information about the service can be found at Please note, this service is scale triggered to draw below 1:37,000. There is also a separate overview map service that identifies the 12 counties currently available in the parcel polygon service. Available data is limited to those counties that have given permission to the Statewide Parcel Program to make their parcel boundaries publically available. An updated service will be published periodically. For more information about how to include your county's parcel data in the web service, please contact Statewide Parcel Program Manager Robert Gehrer at 518-242-5047.

PSAP and Emergency Service Boundaries (ESB) Pilot Project

Our pilot project with Albany County to create emergency service boundaries in the draft NENA standard is nearly complete. We've had several interactive editing sessions with Albany County, both in person and via WebEx. Their project to update the CAD software has kicked off, and we are involved in order to facilitate the use of the existing SAM Address Points and NYS Streets data as well as ensure the ESB data is successfully incorporated into the final product. Counties that have already created their emergency service boundaries are invited to share them with us in order to be incorporated into a statewide layer. Look for our survey to the 911 community on the status of your ESB data in GIS format! Please tell us if you have ESB data that you can share, or if you will soon need it in order to upgrade your CAD software. Please contact Jason Baum at 518-242-5175 to share your boundaries or to learn more about the project.

NG9-1-1 NOW Coalition

In late February, the NG9-1-1 NOW Coalition ( was officially launched to "promote an accelerated implementation of NG911 throughout the nation." Coalition members NENA, NASNA, and iCERT have stated that their goal is "By the end of the year 2020, all 911 systems and centers in all 56 states and territories will have sufficiently funded, standards-based, end-to-end, IP-based 911 capabilities, and will have retired legacy 911 systems, without any degradation in service to the public." The line in the sand that has been drawn has big implications for GIS data preparedness. To meet this goal, every PSAP must minimally have PSAP Boundaries, Emergency Service Boundaries (law, fire EMS), and Road Centerline GIS data layers, with an Address Point layer strongly recommended. Every address in your ALI must be able to be mapped to an Address Point (or minimally to a Street Centerline), every MSAG range must be within Street Centerline range(s), and boundaries must not overlap or have gaps. GIS data cleanup is a lengthy process so don't delay! Contact the SAM Team for Address Point and Street Centerline data maintenance guidance and Jason Baum for ESB data guidance.

Update on the NENA NG9-1-1 GIS Data Model

In December 2014, the NG9-1-1 GIS Data Model was released for a NENA All Committee Review. Over 150 individual comments were submitted as well as 5 separate documents containing tracked changes and 200 more comments. Comment resolution progressed through 2015 but slowed in the fall with a co-chair's retirement. In February, Cheryl Benjamin volunteered to co-chair the group to help move the document forward. Comment resolution was completed at the end of April and responses to the Commenters are being prepared. Due to the amount of change in the document, NENA has indicated the document must go out for another All Committee Review and comment resolution. The goal is to have the document ready for Public Review this calendar year.

News from the National States Geographic Information Council (NSGIC)

News of the NG9-1-1 NOW Coalition broke during NSGIC's mid-year meeting. This was very timely as Cheryl Benjamin, in her capacity as NSGIC's official liaison to NENA, had previously arranged a meeting between NSGIC leadership and NENA leadership during the conference week to discuss mutual items of concern. An outcome of the meeting was NSGIC's endorsement of the NOW Coalition ( NSGIC's NG9-1-1 Committee is monitoring activity of the Coalition's five focus groups, providing GIS expertise as requested. In other NSGIC news, Cheryl Benjamin was appointed to the NSGIC Board of Directors in late March, filling the seat vacated by Bill Johnson, who recently retired as New York State's Geographic Information Officer. This opportunity allows New York State to stay in a GIS leadership role at the national level and keep on top of important national GIS issues, especially those related to the 9-1-1 community.
