Using ArcGIS and VB.Net for E911 Addressing
Track: Emergency Medical Services/Fire
Authors: Victoria Smith

Prior to GIS being involved addressing was done using paper maps and depending on seasoned employees with historical knowledge. By creating custom tools and the 'Official Addressing Form Application' using VB.Net Putnam County is able to assign, change or add additional addresses quickly, and accurately. Benefits of the tools include: address verification letters and emails for other county offices being automatically generated, quality control, and spatial correlation between address points and other layers such as the emergency service zones. Error checking has eliminated common mistakes such as street name misspellings, inaccurate address house numbers, and using the wrong street etc. History can be tracked for addresses and parcels. The E911 staff uses photos, tax maps and aerials to aid them in assigning addresses. These items are encapsulated into a set of tools to make the process as straightforward and efficient as possible.
