Geographic Information Systems (GIS)

Geographic Information Systems (GIS)


While Geographic Information System (GIS) data has played a role in legacy 9-1-1 environments, GIS takes center stage in Next Gen 9-1-1, delivering enhanced functionality that dramatically reduces response times.

Even if your PSAP isn’t making the move to Next Gen 9-1-1 right away, having GIS data that is accurate, up-to-date and synchronized across the local, regional and state level is essential to improving legacy 9-1-1 system response times and optimizing PSAP operations. It’s also the critical first step in the adoption of Next Gen 9-1-1, so your data will be ready when you’re ready to make the system transition.

At West, call routing is second nature. We’re the only strategic partner with the solutions for and experience in both call routing and GIS to help you navigate this new and unfamiliar terrain. We have the historical understanding of how legacy systems have handled 9-1-1 calls, how best to manage call routing during the current “Now Gen 9-1-1™” transitional phase, and how to prepare for future technology developments. We have the tools you need to get from Legacy to Now Gen 9-1-1 to Next Gen 9-1-1, no matter where you are in the process.
