The paper maps are gone. So are the Rolodexes, typed lists, CRT monitors and push-button phones. The workstations where many public safety call takers and dispatchers sit today are less cluttered, more capable and easier to use than their forerunners of 10 or 20 years ago. But, of course, there is still room for improvement, say emergency telecommunications professionals. And those systems at public safety answering points (PSAPs) will need to evolve even further when next-generation 911 (NG-911) technology becomes a reality.
