This interesting article on the NYPD's use of data analytics came across my desk the other day. Here is the abstract:
The New York City Police Department’s Lower Manhattan Security Coordination Center integrates data from a variety of sources, including sensors (cameras, license plate readers, and environmental detectors) and records (arrests, complaints, summonses, 911 calls, etc.). Analyzing this data to inform decision making has required the development of several coordinated processes. These processes are leading to increased efficiency and effectiveness as well as improved situational awareness for senior leadership
This is what Big Data looks like in the real world.
