"The human eye is an incredibly powerful instrument, capable of discerning pattern and nuance with startling speed and efficiency. GIS capitalizes on this most powerful of the senses to provide police personnel with a visual gateway to the databases they collect in the course of their business. The ability of GIS to not only visualize, but to analyze immense datasets provides insights that would otherwise remain undetected."
-Tom Casady, Chief of Police, Lincoln Police Department (NE)
